2.1.5 Magadha Empire

Amongst the sixteen Mahajanapadas, the kingdom of Magadha rose to prominence under a number of dynasties that peaked in power under the reign of Asoka Maurya, one of India's most legendary and famous emperors. The kingdom of Magadha had emerged as a major power following the subjugation of two neighbouring kingdoms, and possessed an unparalleled military.

Haryanka dynasty

According to tradition, the Haryanka dynasty founded the Magadha Empire in 684 BC, whose capital was Rajagriha, later Pataliputra, near the present day Patna. This dynasty was succeeded by the Shishunaga dynasty.

Shishunaga dynasty

This period saw the development of two of India's major religions. Gautama Buddha in the 6th or 5th century BC was the founder of Buddhism, which later spread to East Asia and South-East Asia, while Mahavira founded Jainism. This dynasty lasted till 424 BC, when it was overthrown by the Nanda dynasty.

Nanda dynasty

The Nanda dynasty was established by an illegitimate son of the king Mahanandin of the previous Shishunaga dynasty. Mahapadma Nanda died at the age of 88, ruling the bulk of this 100-year dynasty. The Nandas were followed by the Maurya dynasty. It is said that rumors of the huge size of the Nanda army was in part responsible for the retreat of Alexander from India.

Maurya dynasty

In 321 BC, exiled general Chandragupta Maurya, under direct patronage of the genius of Chanakya, founded the Maurya dynasty after overthrowing the reigning king Dhana Nanda to establish the Maurya Empire. During that time, most of the subcontinent was united under a single government for the first time. Capitalising on the destabilization of northern India by the Persian and Greek incursions, the Mauryan empire under Chandragupta would not only conquer most of the Indian subcontinent, but also push its boundaries into Persia and Central Asia, conquering the Gandhara region. Chandragupta Maurya was influenced by the jainacharya Bhadrabahu and he adopted Jainism.He is credited for the spread of Jainism in southern Indian region. Chandragupta was succeeded by his son Bindusara, who expanded the kingdom over most of present day India, barring Kalinga, and the extreme south and east, which may have held tributary status. Modern day India is an image of the Mauryana, that tied all the peoples and cultures of the erstwhile separate kingdoms under one banner, and predicted a common destiny for all Indians (then mainly Hindus and Buddhists). The tradition was continued later by the Mughals and the British, who formed similar empires.

Bindusara's kingdom was inherited by his son Ashoka The Great who initially sought to expand his kingdom. In the aftermath of the carnage caused in the invasion of Kalinga, he renounced bloodshed and pursued a policy of non-violence or ahimsa after converting to Buddhism. The Edicts of Ashoka are the oldest preserved historical documents of India, and from Ashoka's time, approximate dating of dynasties becomes possible. The Mauryan dynasty under Ashoka was responsible for the proliferation of Buddhist ideals across the whole of East Asia and South-East Asia, fundamentally altering the history and development of Asia as a whole. Ashoka the Great has been described as one of the greatest rulers the world has seen. Ashoka's grandson Samprati adopted Jainism.He was influenced by the teachings of a great jain acharya Arya Suhasti. Following the lines of Ashoka, Samprati spread Jainism in many parts of this world and Indian sub-continent.It is said that Samprati built 1,25,000 Jain Temples all over India, many of which are worshipped today as well.

Sunga dynasty

The Sunga dynasty was established in 185 BC, about fifty years after Ashoka's death, when the king Brihadratha, the last of the Mauryan rulers, was brutally murdered by the then commander-in-chief of the Mauryan armed forces, Pusyamitra Sunga, while he was taking the Guard of Honour of his forces. Pusyamitra Sunga then ascended the throne.

Kanva dynasty

The Kanva dynasty replaced the Sunga dynasty, and ruled in the eastern part of India from 71 BC to 26 BC. The last ruler of the Sunga dynasty was overthrown by Vasudeva of the Kanva dynasty in 75 BC. The Kanva ruler allowed the kings of the Sunga dynasty to continue to rule in obscurity in a corner of their former dominions. Magadha was ruled by four Kanva rulers. In 30 BC, the southern power swept away both the Kanvas and Sungas and the province of Eastern Malwa was absorbed within the dominions of the conqueror. Following the collapse of the Kanva dynasty, the Satavahana dynasty of the Andhra kindgom replaced the Magandhan kingdom as the most powerful Indian state.

2.1.4 Mahajanpadas

During the life time of Lord Gautam Buddha, sixteen great powers (Mahajanpadas/Mahajanapadas) existed in the 7th and early 6th centuries BC. Among the more important republics were the Sakyas of Kapilavastu and the Licchavis of Vaishali. Besides the republics, there were monarchical states, among which the important ones were Kaushambi (Vatsa), Magadha, Kosala and Avanti. These states were ruled by vigorous personalities who had embarked upon the policies of aggrandisement and absorption of neighbouring states. However, there were distinct signs of the republican states while those under the monarchs were expanding.


The political structure of the ancient Indo-Aryans appears to have started with semi-nomadic tribal units called "Jana". Early Vedic texts attest several Janas or tribes of the Aryans, living in semi-nomadic tribal state, fighting among themselves and with other Non-Aryan tribes for cows, sheep and green pastures. These early Vedic Janas later coalesced into Janapadas of the Epic Age.

The term "Janapada" literally means the foothold of a tribe. The fact that Janapada is derived from Jana points to an early stage of land-taking by the Jana tribe for a settled way of life. This process of first settlement on land had completed its final stage prior to the times of Buddha and Panini. The Pre-Buddhist North-west region of Indian sub-continent was divided into several Janapadas demarcated from each other by boundaries. In Panini, Janapada stands for country and Janapadin for its citizenry. These Janapadas were named after the tribes or the Janas who had settled in them. By circa 600 BCE, many of these Janapadas had further evolved into larger political entities by the process of land-grabbing which eventually led to the formation of kingdoms known in Buddhist traditions as the Mahajanapadas or the great nations (Sanskrit: Maha = great, Janapada = country).

The Buddhist and other texts only incidentally refer to sixteen great nations (Solasa Mahajanapadas) which were in existence before the time of Buddha. They do not give any connected history except in the case of Magadha. The Buddhist Anguttara Nikaya, at several places, gives a list of sixteen nations:

1. Kasi                                                                         9. Kuru

2. Kosala                                                                     10. Panchala

3. Anga                                                                       11. Machcha (or Matsya)

4. Magadha                                                                  12. Surasena

5. Vajji (or Vriji)                                                          13. Assaka

6. Malla                                                                        14. Avanti

7. Chedi                                                                       15. Gandhara

8. Vatsa (or Vamsa)                                                      16. Kamboja



The Jaina Bhagvati Sutra gives slightly different list of sixteen Mahajanapadas viz: Anga, Banga (Vanga), Magadha, Malaya, Malavaka, Accha, Vaccha, Kochcha (Kachcha?), Padha, Ladha (Lata), Bajji (Vajji), Moli (Malla), Kasi, Kosala, Avaha and Sambhuttara. Obviously, the author of Bhagvati has a focus on the countries of Madhydesa and of far east and south only. He omits the nations from Uttarapatha like the Kamboja and Gandhara. The more extended horizon of the Bhagvati and the omission of all countries from Uttarapatha clearly shows that the Bhagvati list is of later origin and therefore less reliable (Political History of Ancient India, 1996, p 86; History & Culture of Indian People, Age of Imperial Unity, p 15-16).

The main idea in the minds of those who drew up the Janapada lists was basically more tribal than geographical, since the lists include names of the people and not the countries. As the Buddhist and Jaina texts only casually refer to the Mahajanapadas with no details on history, the following few isolated facts, at best, are gleaned from them and other ancient texts about these ancient nations.

2.1.3 Vedic Period

The Aryans, or Vedic civilization were a new start in Indian culture and they adopted almost nothing of Harappan culture. They built no cities, no states, no granaries, and used no writing.

Instead they were a warlike people that organized themselves in individual tribal, kinship units, the jana. The jana was ruled over by a war-chief. These tribes spread quickly over northern India and the Deccan. In a process that we do not understand, the basic social unit of Aryan culture, the jana, slowly developed from an organization based on kinship to one based on geography.

The jana became a janapada, or nation and the jana-rajya , or tribal kingdom, became the jana-rajyapada, or national kingdom. So powerfully ingrained into Indian culture is the jana-pada, that Indians still define themselves mainly by their territorial origins. All the major territories of modern India, with their separate cultures and separate languages, can be dated back to the early jana-padas of Vedic India.

The earliest history of the Aryans in India is called the Rigvedic Period (1700-1000 BC) after the religious praise poems that are the oldest pieces of literature in India. In this early period, their population was restricted to the Punjab in the northern reaches of the Indus River and the Yamuna River near the Ganges.

They maintained the Aryan tribal structure, with a raja ruling over the tribal group in tandem with a council. Each jana seems to have had a chief priest; the religion was focused almost entirely on a series of sacrifices to the gods. The Rigvedic peoples originally had only two social classes: nobles and commoners. Eventually, they added a third: Dasas , or "darks." These were, we presume, the darker-skinned people they had conquered.

By the end of the Rigvedic period, social class had settled into four rigid castes: the chaturvarnas, or "four colors." At the top of the chaturvarnas were the priests, or Brahmans. Below the priests were the warriors or nobles (Kshatriya), the craftspeople and merchants (Vaishya), and the servants (Shudra), who made up the bulk of society. These economic classes were legitimated by an elaborate religious system and would be eventually subdivided into a huge number of economic sub-classes which we call "castes." Social class by the end of the Rigvedic period became completely inflexible; there was no such thing as social mobility.

In the early centuries of Later Vedic Period or Brahmanic Period (1000-500 BC), the Aryans migrated across the Doab, which is a large plain which separates the Yamuna River from the Ganges. It was a difficult project, for the Doab was thickly forested; the Aryans slowly burned and settled the Doab until they reached the Ganges.

While the Rig Veda represents the most primitive religion of the Aryans during the Rigvedic Period, the religion of the Later Vedic period is dominated by the Brahmanas, or priestly book, which was composed sometime between 1000 and 850 BC. Later Vedic society is dominated by the Brahmans and every aspect of Aryan life comes under the control of priestly rituals and spells. In history as the Indians understand it, the Later Vedic Period is the Epic Age; the great literary, heroic epics of Indian culture, the Mahabharata and the Ramayana, though they were composed between 500 and 200 BC, were probably originally formulated and told in the Later Vedic Period. Both of these epics deal with heroes from this period and demonstrate how Aryan cultural values, as we can understand them from the Rig Veda , are being transformed by mixing with Indus cultures.

2.1.2 Indus Valley Civilization

Archaeologists were always puzzled by Vedic texts (dated c.1500 - 900 BC) that talked about "nomadic invaders conquering mighty citadels under the banner of their God, Indra". However, no trace of the 'mighty citadels' had ever been found, nor of their mysterious inhabitants, the Dasas.

Then, in 1856, six miles from the river Ravi, in the foothills of the Himalayas, railway construction workers came upon a small crumbling hill of fire-baked bricks. These they quickly appropriated for the railway line's ballast. Along with the bricks, certain steatite (soapstone) seals were found. Archaeologists, notably Sir John Cunningham, quickly confirmed their antiquity.  Thus started a voyage of amazing discovery during which archaeologists unearthed the remains of an ancient civilization, which had its epicenter in the plains of the Indus.

Some 5000 years ago, a nomadic people made their way into northwest India from Sumeria (modern day Iran) by means of the Mula Pass across the Himalayas, near modern Karachi, and there found a fabulously rich land, fertilized by the great river systems of the Indus, Ravi, Beas, Chenab and Sutlej. This same area forms modern-day Punjab. Compared to the deserts of Iran, this was God's blessed land, with ample water, fodder and fuel supply. Clay for making bricks was plentiful in the riverbeds and so was wood to burn the bricks.

Over a period of a thousand years, these immigrants spread over an area of half a million square miles

The Indus Valley Civilization (c. 3300 - 1700 BCE, flourished 2600 - 1900 BCE) flourished in the Indus and Ghaggar-Hakra river valleys primarily in what is now Pakistan and western India, extending westward into Balochistan. The mature phase of this civilization is known as the Harappan Civilization, after the first of its cities to be excavated, Harappa. Excavation of Indus Valley Civilization sites has been ongoing since the 1920s.

The peaceful life of the Harappan people bred a sense of complacency. Hence, when the Aryan invaders poured in from the Northwest, they encountered little or no resistance. City after city fell, and the pathetic remains of the people were either assimilated into the conquerors' way of life, or fled further south. In fact, the fall of Mohenjo-daro, almost 3,500 years ago, typified this decay. 

In terms of achievements in town planning and civil administration, this was a great setback, as more than a thousand years were to pass before anything of this magnitude was accomplished in India again. 

The invaders were a nomadic people, unused to urban life. They revered all natural phenomena, ascribing divinity to animals, the wind, the trees, the sky and the water, among myriads of others. It was during this age that the Vedas began to be composed - this formed the basis of early Hinduism.

2.1.1 Prehistoric India

The Indian prehistoric era is one of the most fascinating and intriguing eras to read about. Though there is speculation about when it originated, historians quote the approximate period from 200000 B.C to about 3500 - 2500 B.C. It is estimated that the first humans to set their foot in the Indian sub continent between 200000 B.C and 40000 B.C. Pre historic India has been divided into four major eras.

• Stone Age
• Paleolithic Era
• Mesolithic Era 
• Neolithic Era.

The Bronze Age is also mentioned here though it comes after these four eras. Further information about Indian prehistory is given below.

Stone Age

The Stone Age was the era when early man used stones for functional and useful purposes. The Stone Age is further classified into three categories which are the Paleolithic Age, Mesolithic Age and Neolithic Age. These divisions have been made on the basis of the kind of stone tools that were used during these times.
Paleolithic Age

The Paleolithic Age lasted till about 8000 B.C. In this age, man was essentially a food gatherer. He learnt to make weapons out of stones and also mastered the skill of hunting animals. The crude weapons were slowly carved properly and were made sharp and pointed. These special weapons were made by shredding the sides of a stone with a heavier stone. Man also learnt how to create fire and make use of it.
Mesolithic Age

The Mesolithic Age lasted from 8000 B.C - 4000 B.C. In this age the size of the groups grew to form small communities. The number of mouths to feed increased and needed constant nurturing for continuation. The tools improved and became more refined and sharp. There was a drastic change in the food and clothing of man. The tools were modified and now the sharp stones were attached to strong tree branches using ropes and vines. These new weapons or hand axes could be flung on animals from a safe distance. Apart from this, farming techniques were developed and man began to grow crops. Man also learnt to draw and paint and the evidence is found in the form of cave paintings found in India.
Neolithic Age

The Neolithic Age lasted from 4000 B.C - 2500 B.C and is known as the last stage of the Stone Age era. The main features of this age were the finely flaked weapons and small tools made of stone that were used for day to day work. This age also saw domestication of cows, horses and other poultry and farm animals. Their products were used for dairy and meat items. The wheel, which was a very important invention, was created during this age. Shortly after this age around 1800 B.C, tools were made of copper and bronze and were used for many practical purposes.
Bronze Age

The Bronze Age is the era when metals were used and improvised for making tools and other weapons. This age came immediately after the Neolithic Age and aided in the development of the metallurgy industry. It came into being in 3500 B.C in the Middle East. The Bronze Age in India is roughly estimated to have begun around 3300 B.C. It almost coincided with the beginning of the Indus Valley Civilization. People living in Indus Valley produced bronze, copper and tin thus developing new techniques of metallurgy.

2.1 Ancient Era

The Indus Valley Civilization existed in between 3000-1500 BC while the earlier Kot Diji cultures, of the pre-Indus period, existed in the period of approximately 3300-2800 BC. Harappa and the city of Mohenjo-Daro were the greatest achievements of the Indus valley civilization. These cities are well known for their impressive, organized and regular layout.

Then came Aryans who composed these evocative hymns to nature and celebrated life exuberantly referred to themselves as Aryas usually anglicised as Aryan meaning 'noble'. The 6th Century B.C. was the period of Magadh Kingdom. Chandragupta Maurya ousted the oppressive ruler of Magadh to find his own dynasty that existed from 322 - 298 B.C.

The most famous Maurya King Ashoka the Great ruled from 273 - 232 B.C over a large kingdom stretching from Kashmir and Peshawar in the North and Northwest to Mysore in the South and Orissa in the East. He after witnessing the carnage at the battle field of Kalinga (269 B.C.) in Orissa, dedicated himself to Dharmma ( righteousness ).

In the subsequent centuries, after the Ashoka empire disintegrated, India suffered a series of invasions, and often fell under the spell of foreign rulers - Indo Bactrians, the Sakas and others. After the next 400 years of instability the Guptas established their kingdom.

Kalidas, the famous Sanskrit poet and dramatist, author of Abhijnana Shankuntalam, Kumarsambhavam and Meghadutam is believed to have adorned the Gupta court. Also the great mathematicians like Aryabhatta and astronomers like Varahmihir lived during this period. The dazzling wall paintings of the Ajanta caves too are traced back to this era.

Cholas, Pandayas and Pallavas ruled over the southern part of India during the medieval period of India's history. Cholas ruled the territory of Deccan (today the districts of Thanjavur and Tiruchirapally) while the Pandyas reined around present day Tirunelvelli and Madurai.

Pallavas of Kanchi rose to prominence in the 4th Century A.D. and ruled unchallenged for about four hundred years. The Nayanar and Alvar saint poets belong to this period. The gemlike shore temples at Mahabalipuram date to this period. The Cholas overthrew the Pallavas were in the 9th Century and regained political primacy in south India. The 15th Century saw the decline of the Pandyas.

2.Indian History

India is a country with a rich history and culture. Home to the Indus Valley civilization and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history. Four major world religions, Hinduism, Buddhism, Jainism and Sikhism originated here, while Zoroastrianism, Judaism, Islam and Christianity arrived in the first millennium AD and mingled into the region's diverse culture. India became a modern nation-state in 1947 after a struggle for independence that was marked by widespread nonviolent resistance. The history of India can be divided into four major segments,

1. Ancient era
2. Medieval era
3. Modern era
4. Post-independence era

The hallmark of Indian history dates back to the stone age with paintings at the Rock Shelters of Bhimbetka in Madhya Pradesh. These paintings symbolise the earliest known traces of human life in India. The first known permanent settlements appeared over 9,000 years ago and gradually developed into the Indus Valley Civilization, dating back to 3300 BCE in western India. It was followed by the Vedic Civilization, which laid the foundations of Hinduism and other cultural aspects of early Indian society. From around 550 BCE, many independent kingdoms and republics known as the Mahajanapadas were established across the country.

The empire built by the Maurya dynasty under Emperor Ashoka united most of South Asia in the third century BCE. From 180 BCE, a series of invasions from Central Asia followed, including those led by the Indo-Greeks, Indo-Scythians, Indo-Parthians and Kushans in the north-western Indian subcontinent. From the third century CE, the Gupta dynasty oversaw the period referred to as "The Golden Age" of Indian history. Among the notable South Indian empires were the Chalukyas, Rashtrakutas, Hoysalas, Pallavas, Pandyas, and Cholas. Science, engineering, art, literature, astronomy, and philosophy flourished under the patronage of these kings. Paintings at the Ajanta Caves in Aurangabad, Maharashtra were made in the 6th century.

Following invasions from Central Asia between the tenth and twelfth centuries, much of north India came under the rule of the Delhi Sultanate, and later the Mughal dynasty. Mughal emperors gradually expanded their kingdoms to cover large parts of the subcontinent. Nevertheless, several indigenous kingdoms, such as the Vijayanagara Empire, flourished, especially in the south. In the seventeenth and eighteenth century, the Mughal supremacy declined and the Maratha Empire became the dominant power. From the sixteenth century, several European countries, including Portugal, Netherlands, France, and the United Kingdom, started arriving as traders and later took advantage of the fractious nature of relations between the kingdoms to establish colonies in the country.

During the first half of the twentieth century, a nationwide struggle for independence was launched by the Indian National Congress and other political organizations. Led by Mahatma Gandhi, and displaying commitment to ahimsa, or non-violence, millions of protesters engaged in mass campaigns of civil disobedience. Finally, on 15 August 1947, India gained independence from British rule, but was partitioned, in accordance to wishes of the Muslim League, along the lines of religion to create the Islamic nation-state of Pakistan. Three years later, on 26 January 1950, India became a republic and a new constitution came into effect.

The history of India is a mingle between the East and the West. India has always been an invader's paradise, while at the same time its natural isolation and magnetic religions allowed it to adapt to and absorb many of the peoples who penetrated its mountain passes. No matter how many Persians, Greeks, Chinese nomads, Arabs, Portuguese, Britishers and other raiders had their way into this great country, many of them merged into the society giving rise to a country full of diversity in terms of culture, religion, language and architecture.

1.Overview of India

Indian history and culture is full of richness and affluence, which undoubtedly has had a significant impact on the evolution of the current society. 
Home to the Indus Valley civilization and a region of historic trade routes and vast empires, the Indian history is identified with its commercial and cultural wealth over the past thousands of years. 

Four major world religions, Hinduism, Buddhism, Jainism and Sikhism originated here, while Zoroastrianism, Judaism, Islam and Christianity arrived in the first millennium AD and mingled into the region's diverse culture. 

India became a modern nation-state in 1947 after a struggle for independence that was marked by widespread nonviolent resistance. The history of India can be divided into four major segments, the ancient era, the medieval era, the modern era and the post-independence era. 

The hallmark of Indian history dates back to the stone age with paintings at the Rock Shelters of Bhimbetka in Madhya Pradesh. These paintings symbolize the earliest known traces of human life in India.

A number of invasions from Central Asia between the tenth and twelfth centuries is an important landmark in history of India, as much of north India came under the rule of the Delhi Sultanate, and later the Mughal dynasty. Mughal emperors gradually expanded their kingdoms to cover large parts of the subcontinent. Nevertheless, several indigenous kingdoms, such as the Vijayanagara Empire, flourished, especially in the south. In the seventeenth and eighteenth century, the Mughal supremacy declined and the Maratha Empire became the dominant power.

The first half of the twentieth century is an important period in the history of India, as a nationwide struggle for independence was launched by the Indian National Congress and other political organizations. Led by Mahatma Gandhi, and displaying commitment to ahimsa, or non-violence, millions of protesters engaged in mass campaigns of civil disobedience. Finally, on 15 August 1947, India gained independence from British rule, but was partitioned, in accordance with the wishes of the Muslim League, along the lines of religion to create the Islamic nation-state of Pakistan. Three years later, on 26 January 1950, India became a republic and a new constitution came into effect. Unfortunately, Indian history since independence has been marked by poverty, corruption, and intermittent periods of chaos. 

The history of India is a mingle between the East and the West. India has always been an invader's paradise, while at the same time its natural isolation and magnetic religions allowed it to adapt to and absorb many of the peoples who penetrated its mountain passes. No matter how many Persians, Greeks, Chinese nomads, Arabs, Portuguese, Britishers and other raiders had their way into this great country, many of them merged into the society giving rise to a country full of diversity in terms of culture, religion, language and architecture.

India, officially the Republic of India, is a country in South Asia. It is the 
seventh-largest country by area, the second-most populous country with 
over 1.2 billion people, and the most populous democracy in the world. 
Bounded by the Indian Ocean on the south, the Arabian Sea on the south
-west, and the Bay of Bengal on the south-east. 

It shares land borders with Pakistan to the west; China, Nepal, and Bhutan 
to the north-east; and Burmaand Bangladesh to the east. In the Indian Ocean,
India is in the vicinity of SriLanka and the Maldives; in addition, India's Andaman
and Nicobar Islands share a maritime border with Thailand and Indonesia.
