Chaldean Christians  /kælˈdiːən/ (ܟܠܕܝ̈ܐ) are ethnic Assyrian adherents of the Chaldean Catholic Church, most of whom entered communion with the Catholic Church from the Church of the East, which was already Catholic, but most wanted to stray away from the Catholic Church, causing the split in the 17th and 18th centuries. In addition to their homeland, migrant Chaldean Catholic communities are found in the United States, Sweden, Germany, France, Canada and Australia.
