Why is it said that after Alexander’s death Greece disintegrated?



                     Alexander failed to name an heir and upon his death the great empire which he built was divided up among his generals, called the Diadochi. They engaged in a series of conflicts known as the Wars of the Diadochi. 



                        In forty odd years of fighting, it was settled that there would be no reconstitution of Alexander’s empire. And there emerged a group of big states, each of them a monarchy. They were founded by successful soldiers. They were; Ptolemy, ancestor of Queen Cleopatra, ruled Egypt; Seleucus, founder of the Seleucid dynasty of Persian kings, who controlled the area from Turkey to the Indus. Antigonous took over Greece and much of Turkey. He was the first of the Diadochi who openly declared himself a king. His ambition was to defeat all the other Diadochi rulers.

                    The only city named Alexandria remained to remind people of the great general from Macedonia.
