Modern Turkmenistan was radically transformed by the invasion of the Russian Empire, which conquered the region in the late 19th century. Later, the Russian Revolution of 1917 would ultimately transform Turkmenistan from an Islamic tribal society to a totalitarian Leninist one during the Soviet era. Independence came in 1991, as Saparmurat Niyazov, a former local communist party boss, declared himself absolute ruler for life as Turkmenbashi or "Leader of the Turkmen" and transitioned the newly independent Turkmenistan into an authoritarian state under his absolute control and has thus far resisted the democratization that has influenced many of the other former Soviet Republics. Niyazov ruled until his death on December 21, 2006.
