The All-Albanian Congress (Albanian: Kongresi Gjithë Shqipëtar) was held in Vlorë (then Ottoman Empire, today Republic of Albania) on November 28, 1912. The Congress's participants constituted the Assembly of Vlorë which established Albanian Provisional Government and elected Ismail Kemal as its president.
The Albanian Vilayet (Ottoman Turkish: ÙÙۧÙŰȘ ۧ۱ÙۧÙŰŻ, VilĂąyet-i Arnavid) was a projected vilayet of the Ottoman Empire in the western Balkan Peninsula, which was to include the four Ottoman vilayets with substantial ethnic Albanian populations: Kosovo Vilayet, Scutari Vilayet, Manastir Vilayet, and Janina Vilayet. In some proposals, it included the Salonica Vilayet as well. The creation of the Vilayet was confirmed in September 1912, but negotiations were interrupted a month later in October by the beginning of the First Balkan War. Plans for an Albanian Vilayet were lost with the Partition of Albania.
A separate Albanian vilayet was a part of the agenda of many Albanian organizations and societies since 1877, during the period known as the Albanian National Awakening. Establishment of such a vilayet was agreed between the Albanian rebels and the authorized representatives of the Ottoman government on 4 September 1912, following the Albanian Revolt of 1912. Soon after that agreement however, the First Balkan War broke out and most of the remaining European territory of the Ottoman Empire was occupied by the Balkan League member states. After the army of the Kingdom of Serbia captured Skopje, Ismail Qemali invited a group of Albanians from all four Ottoman vilayets that were agreed to be united into the Albanian Vilayet, to attend an All-Albanian Congress in Valona. There they declared independence on 28 November 1912, and set up the Provisional Government of Albania.
The Albanian Declaration of Independence (Albanian: Deklarata e Pavarësisë) was the declaration of independence of Albania from the Ottoman Empire. Independent Albania was proclaimed in Vlorë on 28 November 1912. Six days later the Assembly of Vlorë formed the first Government of Albania which was led by Ismail Qemali and the Council of Elders (Pleqnia).
The success of the Albanian Revolt of 1912 sent a strong signal to the neighboring countries that the Ottoman Empire was weak. The Kingdom of Serbia opposed the plan for an Albanian Vilayet, preferring a partition of the European territory of the Ottoman Empire among the four Balkan allies. Balkan allies planned the partition of the European territory of the Ottoman Empire among them and in the meantime the territory conquered during First Balkan War was agreed to have status of the Condominium. That was the reason for Qemali to organize an All-Albanian Congress in Vlorë.
The Assembly of Vlorë (Albanian: Kuvendi i Vlorës) was an Albanian assembly constituted during the All-Albanian Congress in Vlorë, on November 28, 1912.
