After the 18th century partitions of Poland (Polish–Lithuanian Commonwealth), the territory was split between the Habsburg Monarchy and the Russian Empire. The modern south-western part of Western Ukraine became the Kingdom of Galicia and Lodomeria, after 1804 crownland of the Austrian Empire. Its northern flank with the cities of Lutsk and Rivne was acquired in 1795 by Imperial Russia following the third and final partition of Poland. Throughout its existence Russian Poland was marred with violence and intimidation, beginning with the 1794 massacres, imperial land-theft and the deportations of the November and January Uprisings. By contrast, the Austrian Partition with its Sejm of the Land in the cities of Lviv and Stanyslaviv (Ivano-Frankivsk) was freer politically perhaps because it had a lot less to offer economically. Imperial Austria did not persecute Ukrainian organizations. In later years, Austria-Hungary de facto encouraged the existence of Ukrainian political organizations in order to counterbalance the influence of Polish culture in Galicia. The southern half of West Ukraine remained under Austrian administration until the collapse of the House of Habsburg at the end of World War One in 1918.
