The Orthodox Church in the territory of Latvia from XVIII to XX cnt.

From the 18th century with the annexation of Latvia to the Russian Empire, the official Orthodox Church spread throughout the Latvian lands. In 1838 the Vicariate of Riga in the Diocese of Pskov was established. In 1847 the Orthodox School of Theology was established in Riga, and in 1851 the Ecclesiastical Seminary started its work.

In 1850 the Vicariate of Riga was reformed into a separate Diocese of Riga. To start with the diocese included the provinces of Livonia and Courland. In 1865 its jurisdiction was extended to the province of Estonia.

By 1914 there were 267 churches within the Diocese of Riga, 71 houses of worship, 273,023 parishioners, and 457 Orthodox schools with 18,227 students.
