When did Albania declare independence?

Albania declared its independence from the Ottoman Empire on November 28, 1912.123

The declaration was issued during a congress held in Vlorë by 83 delegates led by Ismail Qemal. This action, known as the Vlorë proclamation, was taken as neighboring Balkan states invaded Albanian territories during the First Balkan War.123

While the proclamation established the intent for sovereignty, the major European powers formally recognized Albania as an independent principality on July 29, 1913, following the Treaty of London.1
