JUI is a Deobandi organization, part of the Deobandi movement. The JUI formed when members broke from the Jamiat Ulema-e-Hind in 1945 after that organization backed the Indian National Congress against the Muslim League's lobby for a separate Pakistan. The first president of the JUI was Allamah Shabbir Ahmad Usmani. The JUI remained a predominantly religious organization with limited political activity until it was revived by Maulana Mufti Mahmood as a vehicle to oppose the modernization policies of then President of Pakistan, General Ayub Khan. Following the collapse of the Khan regime in the late 1960s, the JUI participated in Pakistan's first general elections in 1970.
JUI is working continuously to convert the law of the country according to its concept of Islam. Ideologically, JUI is described as uncompromisingly rigid, insisting on strict enforcement of traditional Islamic law.
JUI helped establish thousands of madrasahs in Pakistan, more than any other religious movement. Currently in Pakistan, it has three groups: that of Maulana Fazal-ur-Rehman (JUI-F), that of Maulana Sami-ul Haq (JUI-S) and that of Maulana Asmatullah (JUI-N). Maulana Fazal-ur-Rehman and Maulana Asmatullah Both are members of the National Assembly of Pakistan .
