Finland has, for most of its independence, had a semi-presidential system in which the president had much authority and power over both foreign and domestic policy, but in the late 20th and early 21st centuries, the powers of the president have been subject to decrease. In constitutional amendments, which came into effect in 1991, 2000, and 2012, the president's powers have been reduced. The president still leads the nation's foreign politics in conjunction with the Government, and is the commander-in-chief of the Finnish Defence Forces.
