Brenner Pass
At the end of World War I in 1918, the control of the Brenner Pass became shared between Italy and Austria under the Treaty of Saint-Germain-en-Laye (1919). The Treaty of London (1915) secretly awarded Italy the territories south of the Brenner Pass for supporting the Entente Powers. Welschtirol/Trentino, along with the southern part of County of Tyrol (now South Tyrol), was transferred to Italy, and Italian troops occupied Tyrol and arrived at the Brenner Pass in 1919 to 20.
