In 1352 a detachment of Ottoman Turks sailed through Hellespont, now the Dardanelles – the strait separating Europe from Asia, and took Tsimpe, a small Byzantine fort. That is considered to have marked the beginning of the fresh offensive of Asiatic Islamism against the Christian civilization of Europe. The first two assaults at the beginning of the 8th century and at the turn of the 13th century were beaten off by the Christian political powers of the East – Bulgaria, Byzantium and Russia. The third storm, however, led to centuries long confrontation causing, at different times, utmost bracing of all European energies directed at checking the Muslim invasion. It was eventually stopped and fought back for ever no nearer than Vienna. This happened in 1683 and was drowned in seas of European blood. Bulgaria and all the other medieval Christian states in the Balkans were ruined in the twists of this dramatic clash between the European and the Asian civilizations during the l4th-l5th centuries.
