    Summary

    Kasman Singodimedjo (25 February 1904 – 25 October 1982) was an Indonesian lawyer and politician from Purworejo, Central Java. He chaired the Central Indonesian National Committee in the first months of independence, served as the republic's second attorney general, and became one of the most persistent parliamentary advocates of an Islamic basis for the Indonesian state. 1 2 3

    Formation and activism

    He was born near Purworejo to a Muslim family; his father was a local Islamic functionary. The English article notes that many official records give 1908 as his birth year because, on his parents' account, he entered school late and misstated his age to qualify, while the articles and Wikidata follow 1904. Before independence he was active in Muhammadiyah circles and in the politics of organised Islam, including the founding of the Indonesian Islamic Party in 1938, and he later served as the first rector of the Islamic University of Indonesia. 1 2

    Independence and office

    When independence was proclaimed in August 1945, Kasman became the first chairman of the Central Indonesian National Committee (KNIP), the body that stood at the origin of Indonesia's later parliament. He then served as attorney general from 1945 to 1946 and as a junior minister of justice in 1947–1948. The offices matter here as public biography, not as evidence of a personal school of Islam: the record therefore leaves organisational and portfolio successions in prose. 1 2

    The constitutional argument and later years

    In the Constitutional Assembly of the 1950s he argued that the state should be founded on Islam because most Indonesians were Muslims. That argument is recorded as his political position; no source in hand names a school of Islam for him. The English article records imprisonment under both Sukarno and Suharto, and in 2018 the Indonesian state named him a National Hero. He died in Jakarta on 25 October 1982 and was buried in the Tanah Kusir cemetery there. 1 2 3
