Stone Age: Isolated remains of Homo erectus in Hathnora in the Narmada Valley in Central India indicate that India might have been inhabited since at least the Middle Pleistocene era, somewhere between 200,000 to 500,000 years ago.Most traces of the out of Africa migration along the shores of the Indian Ocean seem to have been lost. Due to flooding in the post-Ice Age period, recent finds in Tamil Nadu ( 75,000 years ago, before and after the explosion of the Toba volcano) indicate the presence of the first anatomically modern humans in the area.

Bronze Age: The Bronze Age on the Indian subcontinent began around 3300 BCE with the beginning of the Indus Valley Civilization. It was centered on the Indus River and its tributaries which extended into the Ghaggar-Hakra River valley,the Ganges-Yamuna Doab,Gujarat,and northern Afghanistan. The civilization is primarily located in modern day India (Gujarat, Haryana, Punjab and Rajasthan provinces) and today’s Pakistan (Sindh, Punjab, and Balochistan provinces). Historically part of Ancient India, it is one of the world’s earliest urban civilizations along with Mesopotamia and Ancient Egypt. Inhabitants of the ancient Indus river valley, the Harappans, developed new techniques in metallurgy and produced copper, bronze, lead and tin.

Vedic period: The Vedic period is characterized by Indo-Aryan culture associated with the texts of Vedas, sacred to Hindus, which were orally composed in Vedic Sanskrit. The Vedas are some of the oldest extant texts, next to those of Egypt and Mesopotamia. The Vedic period lasted from about 1500 BCE to 500 BCE, laid the foundations of Hinduism and other cultural aspects of early Indian society. The Aryas established Vedic civilization all over North India, and increasingly so in the Gangetic Plain. This period succeeded the prehistoric Late Harappan during which immigrations of Indo-Aryan speaking tribes overlaid the existing civilizations of local people whom they called Dasyus.

MahaJanapadas: In the later Vedic Age, a number of small kingdoms or city states had covered the subcontinent, many mentioned during Vedic, early Buddhist and Jaina literature as far back as 1000 BCE. By 500 BCE, sixteen monarchies and ‘republics’ known as the Mahajanapadas — Kasi, Kosala, Anga, Magadha, Vajji (or Vriji), Malla, Chedi, Vatsa (or Vamsa), Kuru, Panchala, Machcha (or Matsya), Surasena, Assaka, Avanti, Gandhara, Kamboja — stretched across the Indo-Gangetic plains from modern-day Afghanistan to Bengal and Maharastra. This period was that of the second major urbanisation in India after the Indus Valley Civilization.

Persian and Greek Conquests: Much of the northwestern Indian Subcontinent (present day Eastern Afghanistan and Pakistan) came under the rule of the Persian Achaemenid Empire. 520 BCE during the reign of Darius the Great, and remained so for two centuries thereafter. In 326 BCE, Alexander the Great conquered Asia Minor and the Achaemenid Empire, reaching the north-west frontiers of the Indian subcontinent. There, he defeated King Puru in the Battle of the Hydaspes (near modern-day Jhelum, Pakistan) and conquered much of the Punjab. Alexander’s march East put him in confrontation with the Nanda Empire of Magadha and Gangaridai Empire of Bengal. His army, exhausted and frightened by the prospect of facing larger Indian armies at the Ganges River, mutinied at the Hyphasis (modern Beas) and refused to march further East. Alexander, after the meeting with his officer, Coenus, was convinced that it was better to return.

The Maurya Empire (322–185 B.C), ruled by the Mauryan dynasty, was geographically extensive, powerful, and a political military empire in ancient India. The great Maurya empire was established by Chandragupta Maurya and this empire was flourished by Ashoka the Great. At its greatest extent, the Empire stretched to the north along the natural boundaries of the Himalayas, and to the east stretching into what is now Assam. To the west, it reached beyond modern Pakistan, annexing Balochistan and much of what is now Afghanistan, including the modern Herat and Kandahar provinces. The Empire was expanded into India’s central and southern regions by the emperors Chandragupta and Bindusara, but it excluded a big portion of unexplored tribal and forested regions near Kalinga which was won by Ashoka the Great.

The middle period was a time of notable cultural development. The Satavahanas, also known as the Andhras, was a dynasty which ruled in Southern and Central India starting from around 230 BCE. Satakarni, the sixth ruler of the Satvahana dynasty, defeated the Sunga dynasty of North India. Gautamiputra Satakarni was another notable ruler of the dynasty. Kuninda Kingdom was a small Himalayan state that survived from around the 2nd century BCE to roughly the 3rd century CE. The Kushanas invaded north-western India about the middle of the 1st century CE, from Central Asia, and founded an empire that eventually stretched from Peshawar to the middle Ganges and, perhaps, as far as the Bay of Bengal. It also included ancient Bactria (in the north of modern Afghanistan) and southern Tajikistan. The Western Satraps (35-405 CE) were Saka rulers of the western and central part of India. They were the successors of the Indo-Scythians (see below) and contemporaneous with the Kushans who ruled the northern part of the Indian subcontinent, and the Satavahana (Andhra) who ruled in Central India.

The north-western hybrid cultures of the subcontinent included the Indo-Greeks, the Indo-Scythians, the Indo-Parthians, and the Indo-Sassinids. The first of these, the Indo-Greek Kingdom, founded when the Greco-Bactrian king Demetrius invaded the region in 180 BCE, extended over various parts of present-day Afghanistan and Pakistan. Lasting for almost two centuries, it was ruled by a succession of more than 30 Greek kings, who were often in conflict with each other. The Indo-Scythians was a branch of the Indo-European Sakas (Scythians), who migrated from southern Siberia first into Bactria, subsequently into Sogdiana, Kashmir, Arachosia, Gandhara and finally into India; their kingdom lasted from the middle of the 2nd century BCE to the 1st century BCE. Yet another kingdom, the Indo-Parthians (also known as Pahlavas) came to control most of present-day Afghanistan and northern Pakistan, after fighting many local rulers such as the Kushan ruler Kujula Kadphises, in the Gandhara region. The Sassanid empire of Persia, who were contemporaries of the Guptas, expanded into the region of present-day Pakistan, where the mingling of Indian and Persian cultures gave birth to the Indo-Sassanid culture.

The classical age in India began with the Guptas and the resurgence of the north during Harsha’s conquests around the 7th century, and ended with the fall of the Vijayanagar Empire in the South, due to pressure from the invaders to the north in the 13th century. This period produced some of India’s finest art, considered the epitome of classical development, and the development of the main spiritual and philosophical systems which continued to be in Hinduism, Buddhism and Jainism. King Harsha of Kannauj succeeded in reuniting northern India during his reign in the 7th century, after the collapse of the Gupta dynasty. His kingdom collapsed after his death.

After the Arab invasion of India’s ancient western neighbour Persia, expanding forces in that area were keen to invade India, which was the richest classical civilization, with a flourishing international trade and the only known diamond mines in the world. After resistance for a few centuries by various north Indian kingdoms, short lived Islamic empires (Sultanates) were established and spread across the northern subcontinent over a period of a few centuries. But, prior to Turkic invasions, Muslim trading communities had flourished throughout coastal South India, particularly in Kerala, where they arrived in small numbers, mainly from the Arabian peninsula, through trade links via the Indian Ocean. However, this had marked the introduction of an Abrahamic Middle Eastern religion in Southern India’s pre-existing dharmic Hindu culture, often in puritanical form. Later, the Bahmani Sultanate and Deccan Sultanates flourished in the south.

The post-Mughal era was dominated by the rise of the Maratha suzerianity as other small regional states (mostly post-Mughal tributary states) emerged, and also by the increasing activities of European powers. The Maratha Kingdom was founded and consolidated by Shivaji. By the 18th century, it had transformed itself into the Maratha Empire under the rule of the Peshwas. By 1760, the Empire had stretched across practically the entire subcontinent. This expansion was brought to an end by the defeat of the Marathas by an Afghan army led by Ahmad Shah Abdali at the Third Battle of Panipat (1761). The last Peshwa, Baji Rao II, was defeated by the British in the Third Anglo-Maratha War.

Vasco da Gama’s maritime success to discover for Europeans a new sea route to India in 1498 paved the way for direct Indo-European commerce.The Portuguese soon set up trading-posts in Goa, Daman, Diu and Bombay. The next to arrive were the Dutch, the British—who set up a trading-post in the west-coast port of Surat in 1619—and the French. The internal conflicts among Indian Kingdoms gave opportunities to the European traders to gradually establish political influence and appropriate lands. Although these continental European powers were to control various regions of southern and eastern India during the ensuing century, they would eventually lose all their territories in India to the British islanders, with the exception of the French outposts of Pondicherry and Chandernagore, the Dutch port of Travancore, and the Portuguese colonies of Goa, Daman, and Diu.

The first step toward Indian independence and western-style democracy was taken with the appointment of Indian councilors to advise the British viceroy,and with the establishment of provincial Councils with Indian members the councillors’ participation was subsequently widened in legislative councils.From 1920 leaders such as Mohandas Karamchand Gandhi began mass movements to campaign against the British Raj. Subash Chandara Bose was another freedom fighter who formed army forces against British rule. Bhagat Singh was also an Indian freedom fighter, considered to be one of the most influential revolutionaries of the Indian independence movement. He is often referred to as Shaheed Bhagat Singh (the word shaheed means “martyr”). Veerapandiya Kattabomman was also another freedom fighter who started his freedom movement against British rule by refusing to pay tax to British Government. Revolutionary activities against the British rule also took place throughout the Indian sub-continent, and these movements succeeded in bringing Independence to the Indian sub-continent in 1947. One year later, Gandhi was assassinated.

Along with the desire for independence, tensions between Hindus and Muslims had also been developing over the years. The Muslims had always been a minority, and the prospect of an exclusively Hindu government made them wary of independence; they were as inclined to mistrust Hindu rule as they were to resist the Raj. In 1915, Mohandas Karamchand Gandhi came onto the scene, calling for unity between the two groups in an astonishing display of leadership that would eventually lead the country to independence. The profound impact Gandhi had on India and his ability to gain independence through a totally non-violent mass movement made him one of the most remarkable leaders the world has ever known. He led by example, wearing homespun clothes to weaken the British textile industry and orchestrating a march to the sea, where demonstrators proceeded to make their own salt in protest against the British monopoly. Indians gave him the name Mahatma, or Great Soul, first suggested by the Bengali poet Rabindranath Tagore. The British promised that they would leave India by 1947.

British Indian territories gained independence in 1947, after being partitioned into the Union of India and Dominion of Pakistan. Following the division of pre-partition Punjab and Bengal provinces, rioting broke out between Sikhs, Hindus and Muslims in several parts of India, including Punjab, Bengal and Delhi, leaving some 500,000 dead. Also, this period saw one of the largest mass migrations ever recorded in modern history, with a total of 12 million Hindus, Sikhs and Muslims moving between the newly created nations of India and Pakistan.
