The Rise And Fall of The Great Powers

In the second half of the tenth century, Byzantium embarked on a series of spectacular conquests: first in the southeast against the Arabs, then in Bulgaria, and finally in the Georgian and Armenian lands. By the early eleventh century, the empire was the most powerful state in the Mediterranean. It was also expanding economically, demographically, and, in time, intellectually as well. Yet this imperial project came to a crashing collapse fifty years later, when political disunity, fiscal mismanagement, and defeat at the hands of the Seljuks in the east and the Normans in the west brought an end to Byzantine hegemony. By 1081, not only was its dominance of southern Italy, the Balkans, Caucasus, and northern Mesopotamia over but Byzantium's very existence was threatened.
