The country that is located in the Adriatic Sea, on its mountainous range, has many islands that are major tourist sites, and that suffered a civil war during the period of 1991 to 1995, is Croatia.
Explanation:
Croatia is a country located in the Balkan Peninsula, on the coast of the Adriatic Sea, across from Italy, and it is surrounded by Slovenia and Hungary to the north, Serbia to the east, Montenegro and Bosnia-Herzegovina to the south and southeast and the Adriatic Sea to the west. Although in the past a reknown country for its powerful naval forces, Croatia later on suffered as it passed from the hands of one powerful nation to another, until it gained its recognition as an independent nation after the breakup of Yugoslavia, in 1992. Sharing a lot of common factors with its neighbors, especially Serbia, and Bosnia-Herzegovina, in 1991, and until 1995, this country went through a very serious anti-Serbian movement that caused a civil war that prevented most of the tourism that had been common to its well known islands and touristic sites.
