The Balkan League (Serbia, Montenegro, Greece, and Bulgaria) first conquered Ottoman-held Macedonia and most of Thrace and then fell out over the division of the spoils. Tensions among the Balkan states over their rival aspirations to the provinces of Ottoman-occupied Roumelia, namely Eastern Roumelia, Thrace and Macedonia, subsided somewhat following intervention by the Great Powers in the mid-19th century, aimed at securing both fuller protection for the provinces' Christian majority and protection of the status quo. By 1867 Greece, Serbia and Montenegro have all secured their independence.
