Jamayat-E-Islami (also rendered as Jamiat-e-Islami and Jamiati Islami; Persian: جمعیت اسلامی افغانستان‎‎; "Islamic Society"), sometimes shortened to Jamiat, is a Muslim political party in Afghanistan. The majority of the party, the oldest Muslim political party in Afghanistan, are ethnic Tajiks of northern and western Afghanistan. It has a communitarian ideology based on Islamic law but is also considered moderately progressive. During the Soviet war in Afghanistan and the following civil war in Afghanistan, Jamiat-e Islami was one of the most powerful of the mujahideen groups. Former President of Afghanistan Burhanuddin Rabbani led the party from 1968 to 2011.
