The schism of 1552 was an important event in the history of the Church of the East. It divided the church into two factions, of which one entered into communion with Rome becoming part of the Catholic Church at this time and the other remained independent until the 19th century. Although the Eliya line, which emerged as a result of this schism, did eventually enter into communion with Rome, various Eastern Protestant sects with their origins in the Church of the East emerged as a result of this schism. The Shimon line whose entry into full communion with Rome caused this schism became independent again by the 17th century. The circumstances of the 1552 schism were controversial at the time and have been disputed ever since.
