Alexander the great conquered the Persian Empire and ruled it. When he died, he left no clear heir and his generals divided it amongst themselves, turning these provinces into kingdoms of their own (we today call them the Hellenistic Kingdoms).
One of these Macedonian generals was Ptolemy who was Alexander's governor of Egypt, who eventually declared himself King of Egypt and also took on the traditional Egyptian title of Pharaoh. The generals set about fighting amongst themselves to define their territories.
Some lasted, including Ptolemy in Egypt and Seleucid in Syria who established ruling dynasties. They were all progressively incorporated into the Roman Empire as it expanded to the east. The last of Ptolemy's dynasty was Cleopatra; after her demise Egypt became a province ruled by a Roman governor.
