Out of India Theory - Chronology

Chronology

Neolithic and Bronze Age Indian history is periodized into the Pre-Harappan (ca. 7000 to 3300 BC), Early Harappan (3300 to 2600), Mature Harappan (2600 to 1900) and Late Harappan (1900 to 1300 BC) periods.

The Indian Urheimat proposal put forward by Elst (1999), which he dubs the "emerging non-invasionist model," is as follows: During the 6th millennium BC, the Proto-Indo-Europeans were living in the Punjab region of Northern India. As the result of demographic expansion, they spread into Bactria as the Kambojas. The Paradas moved further and inhabited the Caspian coast and much of Central Asia while the Cinas moved northwards and inhabited the Tarim Basin in northwestern China, forming the Tocharians group of I-E speakers. These groups were Proto-Anatolian and inhabited that region by 2000 BC. These people took the oldest form of the Proto Indo-European (PIE) language with them and, while interacting with people of the Anatolian and Balkan region, transformed it into its own dialect. While inhabiting Central Asia they discovered the uses of the horse, which they later sent back to Urheimat. Later on during their history, they went on to take Western Europe and thus spread the Indo-European languages to that region. During the 4th millennium BC, civilization in India was evolving to become the urban Indus Valley Civilization. During this time, the PIE languages evolved to Proto-Indo-Iranian Some time during this period, the Indo-Iranians began to separate as the result of internal rivalry and conflict, with the Iranians expanding westwards towards Mesopotamia and Persia, these possibly were the Pahlavas. They also expanded into parts of Central Asia. By the end of this migration, India was left with the Proto-Indo-Aryans. At the end of the Mature Harappan period, the Sarasvati river began drying up and the remainder of Indo-Aryans split into separate categories. Some travelled westwards and established themselves as rulers of the Hurrian Mitanni kingdom by around 1500 BC (see Indo-Aryan superstrate in Mitanni). Others travelled eastwards and inhabited the Gangetic basin while others travelled southwards and interacted with the Dravidian people.
