Although the 1913 Treaty of London outlined general territorial terms for Albania, precise borders remained unresolved amid the chaos of World War I, the Paris Peace Conference, and the League of Nations' formation.[citation needed] Marka Gjoni, a chieftain of the predominantly Roman Catholic Mirdita region and tribe in Northern Albania, believed that the new Albanian government was going to ban Catholicism.[7] The Yugoslav government argued that due to the existence of the Mirdita republic, the Albanian response was invalid and threw Albania's status of being a country into question, thus affecting its potential membership in the League.On 2 October 1921, the Assembly of the League of Nations voted unanimously to let the Great Powers settle the border conflict and recommended Albania to accept beforehand the ramifications of their decision.[7][10] Due to Britain's intervention and the possibilities of sanctions against their country, Yugoslavia ended support for Gjoni and withdrew its troops from all Albanian territories as stated in the 1913 Treaty of London, albeit under protest.[4] In the meantime, a new Delimitation Commission was formed which would finalize and confirm the official Albanian border, while the United Kingdom insisted on slight adaptations in the region of Debar, Prizren and Kastrati in the interest of Yugoslavia.
