 The Croatia–Montenegro maritime boundary is disputed in the Bay of Kotor, at the Prevlaka peninsula.The situation was exacerbated by the peninsula's occupation by the Yugoslav People's Army and later by the Serbian-Montenegrin army, which in turn was replaced by a United Nations observer mission that lasted until 2002.Croatia took over the area with an agreement that allowed Montenegrin presence in Croatian waters in the bay, and the dispute has become far less contentious since the independence of Montenegro in 2006.
