The issue of nationality, following independence, politicized the ethnic Chinese and led to the formation of Baperki in 1954, as the first and largest Chinese Indonesian mass organization. Baperki and its majority "peranakan" membership led the opposition against a draft law that would have restricted the number of ethnic Chinese who could gain Indonesian citizenship. This movement was met by the Islamic Masyumi Party in 1956 when it called for the implementation of affirmative action for indigenous businesses. During the 1955 legislative election, Baperki received 178,887 votes and gained a seat on the People's Representative Council (DPR). Later that year, two Baperki candidates were also elected to the Constitutional Assembly.
