In many districts the conversion has been nominal only, and zealous Christians have continued to conduct their worship in secret. Many Mohammedans of this class returned to the faith of their fathers as soon as the tolerance of Government permitted them to do so. As to the warlike mountain clans, the Mirdits, Suliotes, and Acroceraunians, they had no need to bend to the will of the Turks, and remained Greek or Roman Christians. The boundary between Gheges and Tosks coincides approximately with the boundary between these two denominations, the Roman Catholics living to the north of the Shkumbi, the orthodox Greeks to the south of the river. The Hellenes and Zinzares in Southern Albania are orthodox Greeks. The hatred between these two denominations of Christians is intense, and this is the principal reason why the Albanians have not succeeded in regaining their independence, as have the Servians. Southern Albania and Epirus had feudal institutions up to the close of last century. The chiefs of the clans and the semi-independent Turkish pashas lived in strong castles perched upon the rocks, from which they descended from time to time, followed by bands of servitors. War existed in permanence, and property changed hands continuously, according to the fortunes of the sword. Ali the Terrible, of Yanina, put a stop to this state of affairs. He reduced high and low to the same level of servitude, and the central Government now wields the power formerly exercised by lords and heads of families. {123} If we would become acquainted with a social condition recalling the Middle Ages, we must go amongst the independent tribes of Northern Albania. On crossing the Matis we at once perceive a change. Every one goes armed; shepherds and labourers carry a carbine on the shoulder; and even women and children place a pistol in their belts. Families, clans, and tribes have a military organization, and at a moment’s notice are ready to take the field. A sheep missing in a flock, an insult offered in the heat of passion, may lead to war. Not long since the Montenegrin was the most frequent disturber of the peace, for, shut up in his sterile mountains, he was often obliged to turn brigand in order to sustain life, and laid under contribution the fields of his neighbours. The Turks have at all times nourished this hatred between Albanians and Montenegrins. They recompense the warlike services of the tribes of the border clans by exempting them from taxation, and allowing them to govern themselves according to their own laws. Let these immunities be touched, and they will make common cause with their hereditary foes of the Black Mountains.
