Ayatollah Khomeini died in 1989 just months after firing his heir apparent, leaving no designated replacement. With the help of Rafsanjani, Khamenei emerged as the default choice to become the new supreme leader.
Khomeini was a marja (source of emulation, also known as a Grand Ayatollah) in Twelver Shi'a Islam, but is most famous for his political role. In his writings and preachings he expanded the Shi'a Usuli theory of velayat-e faqih, the guardianship of the jurisconsult (clerical authority) to include theocratic political rule by the Islamic jurists.
