It is estimated that a few tens of thousands of Bunjevci were Magyarized in the 19th and early 20th century. Croat national identity was adopted by some Bunjevci in the late 19th and early 20th century, especially by the majority of the Bunjevac clergy, notably one of the titular bishops of Kalocsa, Ivan Antunović (1815–1888), supported the notion of calling Bunjevci and Šokci with the name Croats. Antunović, with journalist and ethnographer Ambrozije Šarčević (1820–1899), led Bunjevci national movement in the 19th century, and in 1880 was founded the "Bunjevačka stranka" ("the Bunjevac party"), an indigenous political party, mostly concentrated on language rights, preservation, and ethnographic work. When their 1905 request for having police patrol and church services in the Croatian language was denied by Hungarian language policy, one group of 1,200 people converted to Orthodoxy.
