The Syriac Catholic Church, also known as Syriac Catholic Patriarchate of Antioch, is an Eastern Catholic Christian originating in the Levant that uses the West Syriac Rite liturgy and has many practices and rites in common with the Syriac Orthodox Church. Being one of the twenty-three Eastern Catholic Churches, the Syriac Catholic Church is a self-governed sui iuris particular church church while it is in full communion with the Holy See and entirety of the Catholic Church.
The Syriac Catholic Church, established in the second half of the 17th century as an Eastern Catholic offshoot of the Syriac Orthodox Church, had around a dozen dioceses in the eastern provinces of the Ottoman Empire in the 18th and 19th centuries. Three of these dioceses were ruined during the First World War in the Assyrian and Armenian massacres, and the 20th century also saw the growth of an important Syriac Catholic diaspora in America, Europe and Australasia. As of 2012 the Syriac Catholic Church has fifteen dioceses, mostly in the Middle East, and four patriarchal vicariates for the diaspora communities.
