One of the most significant consequences of Ottoman rule of Albania was the conversion to Islam of over two-thirds of the population. As the political and economic basis of the Ottoman Empire was not nationality but religion, this conversion created a new group of Muslim Albanian bureaucrats, who not only ruled Albanian provinces for the sultans but also served in important posts as _pashas_ (governors) in many parts of the empire. A number of them became _viziers_ (prime ministers), and one, Mehmet Ali Pasha, at the beginning of the nineteenth century founded an Egyptian dynasty that lasted until the 1950s. Some of the Albanian beys and pashas, especially in the lowlands, became almost independent rulers of their principalities. One of these, Ali Pasha Tepelena, known in history as the Lion of Yannina, whose principality at the beginning of the nineteenth century consisted of the whole area from the Gulf of Arta to Montenegro. By 1803 he had assumed absolute power and negotiated directly with Napoleon and the rulers of Great Britain and Russia. The sultan, however, becoming alarmed at the damage Ali Pasha was doing to the unity of the empire, sent his armies to surround him in Yannina, where he was captured and decapitated in 1822. Under the Turks, Albania remained in complete stagnation and, when the Turks were expelled from the Balkans in 1912, they left it in about the same condition as they had found it. The Albanian highlanders, especially in the north, were never fully subjected, and their tribal organizations were left intact. Turkish suzerainty affected them only to the extent that it isolated them from the world. Thus, they preserved their medieval laws, traditions, and customs. As a result, Western civilization and development did not begin to penetrate Albania in any meaningful way until it became independent in 1912. NATIONAL AWAKENING AND INDEPENDENCE The Albanian national awakening made rapid strides after the Treaty of San Stefano in 1877, imposed on Turkey by the Russians, gave the Balkan Slavic nations large parts of Albania. The Western powers, refusing to accept Russia's diktat on Turkey, met in Berlin the following year to consider revision of the Treaty of San Stefano. Albanian leaders in the meantime convened at Prizren and founded the League for the Defense of the Rights of the Albanian Nation. Although the league was unable to bring sufficient pressure on the Congress of Berlin to save Albania from serious dismemberment, it set in motion a political movement that had tremendous influence on Albanian nationalist activity for decades to come.
