Established in 1912 by Kyai Haji Ahmad Dahlan, Muhammadiyah is Indonesia's oldest Islamic organization and promotes a modern Islam free of superstition and syncretism. Muhammadiyah and its affiliated women's organization, Aisyiyah, have an estimated 29 million members. Muhammadiyah and Aisyiyah (M/A), though technically autonomous, work closely together on social programs throughout Indonesia. The two organizations have collaborated to build schools and universities, as well as hospitals and clinics. M/A have also been instrumental in Indonesia's successful family planning program. USAID supported the family planning efforts of M/A for 35 years, and in 2006 the organizations took full responsibility for these programs. Dr. Din Syamsuddin served as Muhammadiyah general chairman from 2010 to 2015 and in 2011 led Muhammadiyah's condemnation of the Ahmadiyya, an Islamic reform movement whose teachings Muhammadiyah considers unorthodox and heretical. Although M/A are peaceful organizations, they have done little to address religious violence.
