### Bosnia, Dalmatia, Halics
Bosnia In the Middle Ages its territory was part of the Roman Dalmatian province. After the Slavs settled down there in the 6-7th centuries, the Bosnian state developed in the valley of the river Bosna (the name comes from here). During its history it was part of the Byzantine empire, Bulgaria, Croatia and Serbia. From the 12th century the Hungarian kings also hoped to extend their power to Bosnia - as its sign they used the title "King of Rama"-, but their power was only nominal, limited to the feudal vassalage of the Bosnian viceroy. The Bogumil heresy grew to huge dimensions in Bosnia. It interpreted the world as a constant fight between Good and Evil, and according to this doctrine, the material reality is the work of Evil. Enjoying the moral support of the Pope, the Hungarian kings made several unsuccessful attempts to demolish bogumilism. ZSA Dalmatia After the Slavs had settled down there in the 6-7th centuries, the Roman Dalmatian province, which formerly possessed a large territory, was pushed back to the eastern coast of the Adriatic Sea and its neighbouring islands. Its territory originally belonged to the Byzantine empire. After 1000 Croatia and Venice fought for its possession with altering success. After occupying Croatia, the Hungarian Kingdom also hoped to extend its power over its rich merchant cities, such as Zara, Trau, Spalato, Raguza, which led to war either with Venice, or with the Byzantine Empire. ZSA Halics An Eastern Slav principality along the upper reach of the San and Dnester rivers, which received its name from the city of Halics. Its territory fell under the rule of the Kievian Rus at the end of the 10th cenutry. It became independent in the middle of the 12th century, and in 1199 joined the neighbouring Volhinia (Lodomeria) under a common principality. During the 12-13th centuries the Árpád dynasty led several military campaigns against Halich. From the end of the 12th century they tried to take over the principality, but there was no permanent Hungarian rule. In 1240 the Tartars devastated that region and their princes became taxpayers of the Tartars. ZSA
