18th century most followers of the earlier patriarchate chose union with Rome and, with some others, now form the Chaldean Catholic Church. In India, all of the Saint Thomas Christians are still collectively called "Syrian Christians". The majority of the Saint Thomas Christians, who initially depended on the Church of the East, maintained union with Rome in spite of discomforts felt at Latinization by their Portuguese rulers and clergy, against which they protested. They now form the Syro-Malabar Catholic Church. A small group, which split from these in the early 19th century, united at the beginning of the 20th century, under the name of Chaldean Syrian Church, with the Assyrian Church of the East. Those who in 1653 broke with the Catholic Church as dominated by the Portuguese in India and soon chose union with the Syriac Orthodox Church later split into various groups. The first separation was that of the Malabar Independent Syrian Church in 1772. At the end of the 19th century and in the course of the 20th, a division arose among those who remained united with the Syriac Orthodox Church who insisted on full autocephaly and are now called the Malankara Orthodox Syrian Church and those, the Jacobite Syrian Christian Church, who remain faithful to the patriarch. A reunion movement led in 1930 to the establishment of full communion between some of the Malankara Syrian Orthodox and the Catholic Church. They now form the Syro-Malankara Catholic Church.
