On March 17, 1991, the all-Russian referendum on the introduction of the post of President of Russia was held. More than 70% of citizens voted for the introduction of the post of President, elected by direct vote. On 12 June 1991, Boris Yeltsin won 57% of the popular vote in the presidential election. Yeltsin's inauguration took place on 10 July, with the subsequent events of the next half a year making him a head of an independent post-Soviet state, that was renamed to ""Russian Federation"" on 25 December.
