Foundation of First Bulgarian Nation
In 680 the Turkic semi-nomadic Bulgar tribes under the leadership of Asparukh moved south across the Danube and settled in the area between the lower Danube and the Balkan, establishing their capital at Pliska. A peace treaty with Byzantium in 681 marked the beginning of the First Bulgarian Empire.
The Golden Century
The empire reached its zenith under Ivan Asen II (1218–1241), when commerce and culture flourished. The strong economic and religious influence of Tarnovo made it a "Third Rome", unlike the already declining Constantinople.
Ottoman Empire
Tarnovo was captured by the Ottomans after a three-month siege in 1393. After the Battle of Nicopolis in 1396 brought about the fall of the Vidin Tsardom, the Ottomans conquered all Bulgarian lands south of the Danube. The nobility was eliminated and the peasantry was enserfed to Ottoman masters, with much of the educated clergy fleeing to other countries
