Most ''pesantren'' (Islamic boarding schools) in Jakarta are affiliated with the traditionalist Nahdlatul Ulama, modernist organisations mostly catering to a socioeconomic class of educated urban elites and merchant traders. They give priority to education, social welfare programs and religious propagation. Many Islamic organisations have headquarters in Jakarta, including Nahdlatul Ulama, Indonesian Ulema Council, Muhammadiyah, and Jaringan Islam Liberal.
