The modern history of Russia began with the Russian Republic of the Soviet Union gaining more political and economical autonomy amidst the imminent dissolution of the USSR during 1988–1991, proclaiming its sovereignty inside the Union in June 1990, and electing its first President Boris Yeltsin a year later. The Russian SFSR was the largest republic of the Soviet Union, but it had no significant independence before, being the only Soviet republic to not have its own branch of the Communist Party. The RSFSR was the largest of the fifteen republics that made up the USSR, accounting for over 60% of its GDP and over 50% of its population. Russians also dominated the Soviet military and the Communist Party. As such, the Russian Federation was widely accepted as the USSR's successor state in diplomatic affairs and it assumed the USSR's permanent membership and veto in the UN Security Council (see Russia and the United Nations). Prior to the dissolution of the USSR, Yeltsin had been elected President of the RSFSR in June 1991 in the first direct presidential election in Russian history. This ensured that he would be the political leader of the Russian successor state following dissolution. This situation resulted in political turmoil as the Soviet and Russian leadership wrestled for control, which culminated in the 1991 August coup, where the Soviet military attempted to overthrow Mikhail Gorbachev. Although the coup was ultimately averted, this situation contributed to rising instability in the Soviet Union. As the USSR was on the verge of collapse by October 1991, Yeltsin announced that Russia would proceed with radical reforms, including shock therapy policies to introduce capitalism. This caused a sustained economic recession, and GDP per capita levels eventually returned to their 1991 levels by the mid-2000s. Following Yeltsin's resignation in 1999, Russia's politics have since been dominated by Vladimir Putin, serving as either President or Prime Minister. Although the Russian economy has improved significantly under Putin's leadership following relative economic chaos under Yeltsin, Putin has also been widely accused of corruption, authoritarian leadership, and widespread human rights abuses. For the most part, the Russian armed forces were in near complete disarray by 1992, one year after dissolution. This degraded military effectiveness would become all too clear during the 1994 Chechen War, and in the interim posed significant practical challenges for global security and arms control. Under Russian leadership, the Lisbon Protocol ensured that former Soviet republics would disarm themselves of nuclear weapons. This affected Kazakhstan in particular, as it hosted a significant share of the world's nuclear weapons immediately following the dissolution of the Soviet Union. However, the former Soviet republics were able to maintain transnational cooperation in other military areas, like establishing shared responsibility for the rocket and space infrastructure such as the Baikonur Cosmodrome.
