The government ministries founded by Alexander I beginning in 1802 constituted one of the tsar’s most liberal reforms, and the new system of political decision-making closely resembled a constitutional monarchy. There were eight ministries, which replaced the outdated colleges established by Peter I, the "Great" (r. 1682–1725). Each minister reported to Alexander, who made all the final decisions, and with whom they often met to discuss public policy. When Alexander became involved in the conflict with Napoleon, the Committee of Ministers was allowed to make decisions on many domestic issues by majority vote.
