Following partitions of Poland, the Habsburg Monarchy established its crown land of the Kingdom of Galicia and Lodomeria and then West Galicia which in 1803 was merged with Galicia and Lodomeria, which became in 1804 the crownland of the Austrian Empire. The Greek Catholic Church was established on 1807 with metropolitan see based in Lwow and its suffragan dioceses included Chelm and Przemyśl. Following the 1809 Treaty of Schönbrunn the Austrian Empire was forced to cede territory of former West Galicia to Duchy of Warsaw which in 1815 on decision of Congress of Vienna was ceded to the Russian Empire. The Chelm diocese which was located on the territory that for short period time was known as West Galicia ended up under the Russian jurisdiction.
