The expanding Ottoman Empire overpowered the Balkan Peninsula in the fourteenth and fifteenth centuries. At first, the feuding Albanian clans proved no match for the armies of the sultan (see Glossary). In the fifteenth century, however, Skanderbeg united the Albanian tribes in a defensive alliance that held up the Ottoman advance for more than two decades. His family's banner, bearing a black two-headed eagle on a red field, became the flag under which the Albanian national movement rallied centuries later.

Five centuries of Ottoman rule left the Albanian people fractured along religious, regional, and tribal lines. The first Albanians to convert to Islam were young boys forcibly conscripted into the sultan's military and administration. In the early seventeenth century, however, Albanians converted to Islam in great numbers. Within a century, the Albanian Islamic community was split between Sunni (see Glossary) Muslims and adherents to the Bektashi (see Glossary) sect. The Albanian people also became divided into two distinct tribal and dialectal groupings, the Gegs and Tosks. In the rugged northern mountains, Geg shepherds lived in a tribal society often completely independent of Ottoman rule. In the south, peasant Muslim and Orthodox Tosks worked the land for Muslim beys, provincial rulers who frequently revolted against the sultan's authority. In the nineteenth century, the Ottoman sultans tried in vain to shore up their collapsing empire by introducing a series of reforms aimed at reining in recalcitrant local officials and dousing the fires of nationalism among its myriad peoples. The power of nationalism, however, proved too strong to counteract.
