Answer:
Bosnia
Serbia
Explanation:
Austria-Hungary was a powerful country that existed during the 19th century and until the beginning of the 20th century. It was located in Central Europe and the Balkan Peninsula, including the territories of modern day Austria, Hungary, Slovenia, Croatia, Bosnia and Herzegovina, northern Italy, southern Poland, western Ukraine, northern and western Romania, Czech Republic, Slovakia, and northern Serbia (Vojvodina). Multiple nations were not happy by the rule of Austria-Hungary, so they openly opposed it and were trying to get independence, with Bosnia and Serbia being some of those states. Bosnia and Serbia managed to gain independence only after the Austria-Hungary Empire fell apart, so both of them became part of the newly form Kingdom of SHS.
