The ancestors of the Ghazis were tribal nomads who fled from Genghis Khan's Mongols and settled in Anatolia in the 12th century. The word "Ottoman" comes from the name "Osman." After Osman I united the Ghazis, they attacked the Byzantines but bypassed the capital, Constantinople. After the death of Osman I, the Ottomans expanded into the Balkans and Eastern Europe. They captured Thessaloniki from the Venetians in 1387 and Kosovo from the Serbs in 1389. The European crusades of the Middle Ages failed to vanquish them. Finally, in 1453, the Ottomans overcame the heavily fortified city of Constantinople. In the 15th and 16th centuries, further conquests expanded the territory of the Ottoman Empire into Syria, Egypt, Somalia, Mesopotamia, Greece and parts of Hungary.
