Dalhousie’s chief aim was the consolidation of British rule in India. So he adopted the principle of centralization.  

• For the newly acquired territories he devised the ‘Non-Regulation System” under which commissioners were appointed to deal with the administrative problems.  

• They were made responsible to the Governor-General in the Council. He handed over all other powers relating to justice, police, and land revenue to the District Magistrates.
