Ptolemaic dynasty
Ptolemy, was one of Alexander the Great's generals and deputies. He was appointed satrap of Egypt after Alexander's death in 323 BC. In 305 BC, he declared himself King Ptolemy I, later known as "Soter" (savior). The Egyptians soon accepted the Ptolemies as the successors to the pharaohs of independent Egypt. Unlike their previous rulers under the Achaemenid Empire, they usually lived in Egypt. Ptolemy's family ruled Egypt until the Roman conquest of 30 BC.
