Who took over the weak Greek city-states?

Answer 1

Greece was an independent city-state for several ages, until its eventual military decline and defeat led to Roman control in 168 B.C. A while after came the time of Christ, and due to the preachings of Paul the Apostle around 60 A.D., much of the eastern Roman Empire became deeply influenced by Christianity from there on out. Soon after this religious paradigm shift, the Byzantine era began, and for a long period of time Greece was prosperous, and even after centuries of continued attacks from raiders and attempted conquest by neighboring empires, Greece was relatively stable, until the Fourth Crusade and the fall of Constantinople. In the 15th century, most of Greece fell to the rule of the Ottoman Empire, who introduced Islam to the region. However, the Eastern Orthodox faith held strong, and as new ideals spread by the French Revolution took hold, Greece took its stand and declared its own independence as a State in 1821. It is at this point the age of Modern Greece begins, and after continued struggle to maintain and empower their beloved homeland, the Greeks restored much of their native populace and by 1947, its boundaries grew into what they are today. As of now, Greece still remains an independent nation, and it was one of the founding members of the United Nations.
