Explanation:

The Colonisation Bill was passed in 1906. The Punjab Land Alienation Act, 1900 had already caused a feeling of discontent among the elite urban classes, and the Colonisation Bill provided for transfer of property of a person after his death to the government if he had no heirs. The Government could sell the property to any public or private developer.This was completely against the social conditions prevailing in the region and hence it was rejected by all the sides.
The agitation against these measures of the Government was led by Lala Lajpat Rai, he called for "extreme measures". The first of the protests was organised in the Chenab Colony, which was supposed to be the most affected by this bill. The first protest saw various organisations submitting memoranda to the government to redress their grievances, but the government failed to pay any heed to these documents. This agitation was followed by a protest at Lyallpur. 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 both Rai and Ajit Singh.
