Роман Мстиславич
A significant feature in political life of Halychian Principality was the decisive role of nobles and citizens. Halicyans used the principle of ″freedom in princes″ and themselves invited and expelled princes, also correcting their activities. Contrary to the will of Yaroslav Osmomysl who left the throne to his younger son Oleg, the Halychians invited his brother Vladimir II Yaroslavich, and later, after conflict with him, Roman the Great, prince of Volodymyr. But almost immediately Roman was replaced by Andrew - the son of Hungarian King Bela III. The reason for this choice was a complete freedom of government that was guaranteed by Béla and Andrew to Halychians. This period can be considered as the first experience of self-rule government by noblemen and citizens. However, the vulgar behavior of the Hungarian garrison and their attempts to install Roman Catholic rites led to another change in mood and to the throne again was returned Vladimir II, who ruled in Halych next decade up to year 1199.
