The offensive of the Central powers was stopped by Italy at the Battle of Monte Grappa in November 1917 and the Battle of the Piave River in May 1918. Italy took part in the Second Battle of the Marne and the subsequent Hundred Days Offensive in the Western Front. On 24 October 1918 the Italians, despite being outnumbered, breached the Austrian line in Vittorio Veneto and caused the collapse of the centuries-old Habsburg Empire. Italy recovered the territory lost after the fighting at Caporetto in November the previous year and moved into Trento and South Tyrol. Fighting ended on 4 November 1918. Italian armed forces were also involved in the African theatre, the Balkan theatre, the Middle Eastern theatre and then took part in the Occupation of Constantinople. At the end of World War I, Italy was recognized with a permanent seat in the League of Nations' executive council along with Britain, France and Japan.
