 Although later with the 1919 Venizelos–Tittoni agreement, Italy promised to cede them to Greece, Carlo Sforza in 1920 renounced the accord.In 1913, after the end of the First Balkan War, lands of Northern Epirus were ceded to Greece, but Italy challenged the decision and in the Treaty of London the region was given to the newly created Albania.The local Greek population was enraged and created the Autonomous Republic of Northern Epirus, before it was reluctantly ceded to Albania, with peace assured by Italian peacekeeping force until 1919.
