Royal Yugoslav Navy
The Royal Navy (Serbo-Croatian Latin: Kraljevska mornarica; Serbo-Croatian Cyrillic: Краљевска морнарица; КМ), commonly known as the Royal Yugoslav Navy, was the naval warfare service branch of the Kingdom of Yugoslavia (originally called the Kingdom of Serbs, Croats and Slovenes). It was brought into existence in 1921, and initially consisted of a few former Austro-Hungarian Navy vessels surrendered at the conclusion of World War I and transferred to the new nation state under the terms of the Treaty of Saint-Germain-en-Laye.
