The History of India begins with the Indus Valley Civilization, which spread through in the north-western part of the Indian subcontinent, from 3300 BC to 1300 BC. This Bronze Age civilization collapsed at the beginning of the second millennium BC and was followed by the Iron Age Vedic period, which extended over much of the Indo-Gangetic plains and which witnessed the rise of kingdoms known as the Mahajanapadas.
In the fifth century, large parts of India were united under Ashoka. He also converted to Buddhism, and it is in his reign that Buddhism spread to other parts of the Asia. In the reign of Mauryas, Hinduism took shape fundamentally.
In the eight century Islam came to India and by the 11th century it firmly established itself in India. The North Indian dynasties of the Lodhis, Tughlaqs, and numerous others, whose remains are visible in Delhi and scattered elsewhere around North India, were finally succeeded by the Mughal empire, under which India once again achieved a large measure of political unity.
The European presence in India date to the seventeenth century, and it is in the latter part of this century that the Mughal empire began to disintegrate, paving the way for regional states.
During the first half of the 20th century, a natiowide struggle for independence was launched by the Indian National Congress, and later joined by the Muslim League. The subcontinent gained independence from Great Britain in 1947, after being partitioned into the dominions of India and Pakistan.
The History of India can be broadly divided into following three categories.
Starting from Harappa Civilization in 3000 BC till Chola Dynasty in 985 AD.
Starting from Ghazni sacks Somnath Temple in 1026 AD till Siraj-ud-daulah captures Calcutta (Now Kolkatta) in 1756 AD.
Starting from Battle of Plassy in 1757 Till Partition of India and Independence on 15 August 1947.
