Himalayan TreksThe earliest known inhabitants of the region were tribals called Dasas. Later, Aryans came and they assimilated in the tribes. In the later centuries, the hill chieftains accepted suzerainty of the Mauryan empire, the Kaushans, the Guptas and Kanuaj rulers. During the Mughal period, the Rajas of the hill states made some mutually agreed arrangements which governed their relations. In the 19th century, Ranjit Singh annexed/subjugated many of the states. When the British came, they defeated Gorkhas and entered into treaties with someRajas and annexed the kingdoms of others. The situation more or less remained unchanged till 1947. After Independence, 30 princely states of the area were united and Himachal Pradesh was formed on 15th April, 1948. With the recognition of Punjab on 1st November, 1966, certain areas belonging to it were also included in Himachal Pradesh. On 25th January, 1971, Himachal Pradesh was made a full-fledged State. The State is bordered by Jammu & Kashmir on North, Punjab on West and South-West, Haryana on South, Uttar Pradesh on South-East and China on the East.
About 2 million years ago man lived in the foothills of Himachal Pradesh, viz in the Bangana valley of Kangra, Sirsa valley of Nalagarh and Markanda valley of Sirmour. The foothills of the state were inhabited by people from Indus valley civilization which flourished between 2250 and 1750 B.C. People of Indus valley civilization pushed the original inhabitants of Ganga plains who were known as Kolorian people towards north. They moved to the hills of Himachal Pradesh where they could live peacefully and preserve their way of life.
In the Vedas they have been referred to as Dasas, Dasyus and Nishadas while in later works they have been called Kinnars, Nagas and Yakshas. The Kols or Mundas are believed to be the original migrants to the hills of present day Himachal.
The second phase of migrants came in the form of Mongoloid people known as Bhotas and Kiratas. Later on came the third and most important wave of migrants in the form of the Aryans who left their Central Asian home. These laid the base of history and culture of Himachal Pradesh.
