Indonesia is constitutionally a secular state (but the government officially recognizes only six formal religions), with Islam being the dominant religion in the country. Indonesia also has a larger Muslim population than any other country in the world, with approximately 202.9 million identifying themselves as Muslim (87.2% of Indonesia's total population in 2011).[1]

The vast majority adheres to Sunni Islam mainly of the Shafi'i school of jurisprudence (99%).[2][3] There are around one million Shias (0.5%), who are concentrated around Jakarta,[4] and about 400,000 Ahmadi Muslims (0.2%).[5] The remaining 0.3% are adherents of other branches including Wahhabism/Salafism etc. In general, Muslims in Indonesia can be categorized in terms of two orientations: "modernists" who closely adhere to orthodox theology while embracing modern learning, "traditionalists," who tend to follow the interpretations of local religious leaders and religious teachers at Islamic boarding schools (pesantren).
