Solution:Kol Revolt was led by Budhu Bhagat in Chhota Nagpur region in 1831-32.The uprising was a reaction to the appointment of a Political Agent to the Government in South Bihar, and ceded districts nearby around 1819. This resulted in many people moving into these areas which were the lands of numerous Adivasi tribes.
Until the British arrived, these tribes had no rulers and their lands were divided according to families that were bound by "parhas" or conferences. With the application of new land laws, the Kols were exploited by outsiders moving into the area and taking up agriculture and commercial activities that were alien to tribal culture.
Also, many of the lands of the locals were taken away as securities for un-returned loans. Another irritation was the taxation on the movement of products, such as salt that were formerly freely moved. Corrupt official practices and lawlessness followed.
