Himachal Pradesh also known as "Snow-land" is a state of India located in Northern India. The history of the area that now constitutes Himachal Pradesh dates to the Indus valley civilisation that flourished between 2250 and 1750 BC.
During the Vedic period, several small republics known as Janapada existed which were later conquered by the Gupta Empire.After a brief period of supremacy by King Harshavardhana, the region was divided into several local powers headed by chieftains, including some Rajput principalities. These kingdoms enjoyed a large degree of independence and were invaded by Delhi Sultanate a number of times. Later, the British gradually emerged as the paramount power in the region.The states of Chamba, Mandi and Bilaspur made good progress in many fields during the British rule.During World War I, virtually all rulers of the hill states remained loyal and contributed to the British war effort, both in the form of men and materials. Among these were the states of Kangra, Jaswan, Datarpur, Guler, Rajgarh, Nurpur, Chamba, Suket, Mandi, and Bilaspur.Himachal became a part C state on 26 January 1950 with the implementation of the Constitution of India and the Lieutenant Governor was appointed.
