  Twelver Shīʿīsm or Ithnāʿashariyyah is the largest branch of Shia Islam, and the terms Shia Muslim and Shia often refer to the Twelvers by default. The designation Twelver is derived from the doctrine of believing in twelve divinely ordained leaders, known as " the Twelve Imams ". Twelver Shia are otherwise known as Imami or Jaʿfari; the latter term derives from Jaʿfar al-Ṣādiq, the 6th Shīʿīte Imam, who elaborated the Twelver jurisprudence. Twelver Shia constitute the majority of the population in Iran (90%), Azerbaijan (85%), Bahrain (70%), Iraq (65%), and Lebanon (65% of Muslims).
