In 1915, during the First World War, Serbian Macedonia was invaded by Bulgaria, which captured Skopje on 22 October 1915 . Serbia, allied to the Triple Entente, was helped by France, Britain, Greece, and Italy, which formed the Macedonian Front. Following a great Allied offensive in 1918, the Armée française d’Orient reached Skopje 29 September and took the city by surprise. After the end of the World War, Macedonia became part of the new Kingdom of Serbs, Croats, and Slovenes, & later “”Kingdom of Yugoslavia”” in 1929.
