The Peoples Party – known as the Peoples Revolutionary Party between 1924 and 2010 – formed the government from 1921 to 1996 (in a One-party state until 1990) and from 2000 to 2004. From 2004 to 2006, it was part of a coalition with the Democrats and two other parties, and after 2006 it was the dominant party in two other coalitions. The party initiated two changes of government from 2004 prior to losing power in the 2012 election. The Democrats were the dominant force in a ruling coalition between 1996 and 2000, and an almost-equal partner with the Peoples Revolutionary Party in a coalition between 2004 and 2006. An election of deputies to the national assembly on 28 June 2012 resulted in no party having an overall majority; however, as the Democratic Party won the largest number of seats, its leader, Norovyn Altankhuyag, was appointed Prime Minister of Mongolia on August 10, 2012. In 2014, he was replaced by Chimediin Saikhanbileg. The Mongolian Peoples Party won a landslide victory in the Mongolian legislative election, 2016 and the current Prime Minister of Mongolia is Mongolian Peoples Partys Jargaltulgyn Erdenebat.
