Sarekat Islam, formerly Islamists Trade Union (Indonesian: Sarekat Dagang Islam), was a cooperative of Javanese batik traders in the Dutch East Indies and a predecessor of independent Indonesia. The group was founded by Haji Samanhudi, a dealer of batik, in 1905 in Surakarta or 1912. Sarekat Dagang Islam, or Union of Islamic Traders, had as its goal the empowerment of local merchants, especially in the batik industry. The establishment of the organization was inspired by the Jamiat Kheir organization.
As Sarekat Dagang Islam grew, it was reorganized under the name Sarekat Islam. Sarekat Islam's general office was in Surabaya. Early prominent figures of Sarekat Islam included H.O.S. Cokroaminoto and Haji Agus Salim. H.O.S. Cokroaminoto had three famous students, who went on to play a dominant role in Indonesian politics: Soekarno the nationalist, Semaun the socialist and Islamist Kartosuwirjo. Haji Agus Salim joined Sarekat Islam in 1915 and promoted Islamic modernism. Some of Salim's students such as Kasman Singodimedjo, Mohammad Roem and Mohammad Natsir later became prominent Islamic and Nationalist leaders.
