Archbishops of Riga
The archbishops of Riga were also the secular rulers of Riga until 1561 when during the reformation the territory converted from Catholicism to Lutheranism and all church territories were secularized. The see was restored as a diocese of the Catholic Church in 1918 and raised into an archdiocese in 1923.
