Jamaat-e-Islami (Urdu: جماعتِ اسلامی) is an Islamic political organisation and social conservative movement founded in 1941 in British India by the Islamist theologian and socio-political philosopher, Abul Ala Maududi.
Along with the Muslim Brotherhood, founded in 1928, Jamaat-e-Islami was one of the original and most influential Islamist organisations, and the first of its kind to develop "an ideology based on the modern revolutionary conception of Islam".
The group split into separate independent organisations in India and Pakistan -- Jamaat-e-Islami Pakistan and Jamaat-e-Islami Hind—following the Partition of India in 1947. Other groups related to or inspired by Jamaat-e-Islami developed in Bangladesh, Kashmir, Britain, and Afghanistan (see below). The Jamaat-e-Islami parties maintain ties internationally with other Muslim groups.
Maududi was the creator and leader of the militant Jamaat-e-Islami, which became the spearhead of the movement to transform Pakistan from a Muslim homeland into an Islamic state. Though he opposed the creation of Paksitan fearing the liberalism of its founders and the British-trained administrators, he later accepted it as a graudual step to the Islamization of its laws and constitution even though he had earlier condemned the Muslim League for the same approach. Madudi like the traditionalist ulama regarded the six canonical hadiths and the Quran, and also accepted much of the dogma of the four schools of fiqh. His efforts focused on transforming to a "theo-democracy" based on the Sharia which would enforce things like abolition of interest-bearing banks, sexual separation, veiling of women, hadd penalties for theft, adultery, and other crimes. The promotion of Islamic state by Maududi and Jamaat-e Islami had broad popular support.
