Important leaders of this movement include Ajit Singh, Het Thakkar, among others.
The Punjab Land Alienation Act, 1900 had already caused discontent among the elite urban classes, and the Colonisation Bill provided for the transfer of property of a person after he died the government if he had no heirs.
The first of the protests was organised in the Chenab Colony, which was supposed to be the most affected by this bill.
These agitations led to the formation of secret societies like Anjuman-i- Muhibhan-i- Watan, the founder of which was Ajit Singh, a Jat Sikh who was believed to have the backing of Lajpat Rai.
This period saw mass agitations which finally ended in the deportation of Ajit Singh.
