Twelver Shiits

The Twelvers are by far the largest group of Shiite Muslims, because the Iranians are Twelvers. Perhaps eighty percent of the Shiis are Twelvers. Twelvers constitute ninety percent of the modern population of Iran and fifty-five to sixty percent of the population of Iraq. Twelver Shiites are the majority in Iran, Iraq, Azerbaijan and also have substantial populations in Turkey, Pakistan, Lebanon, Syria, India, Afghanistan and Bahrain.
