Jamaat-e-Islami is an Islamist movement founded in 1941 in British India by the Islamist author and theorist Syed Abul Ala Maududi, who was inspired by the Muslim Brotherhood. It is considered one of the most influential Islamist organisations, and was the first to develop an ideology based on the modern revolutionary conception of Islam. Its founding branch in Pakistan is the nation's largest fundamentalist party.
Jamaat-e-Islami was founded to spread Islamic values across the Indian subcontinent and advocate for an Islamic political system. It was formed on 26 August 1941 in Lahore under the leadership of Maududi, who believed that contemporary political ideologies resulted from Western imperialism, and that it was necessary to implement Sharia law to preserve Muslim culture. Maududi believed politics was "an integral, inseparable part of the Islamic faith," and that Islamic ideology and non-Islamic ideologies (such as capitalism and socialism, liberalism or secularism) were mutually exclusive. He saw the creation of an Islamic state as both act of piety, and a cure for social and economic problems faced by Muslims, which he attributed to Western influence.
