The Ptolemaic dynasty (sometimes also known as the Lagids, from the name of Ptolemy I's father, Lagus) was a HellenisticMacedonian royal family which ruled the Ptolemaic Empire in Egypt for nearly 300 years, from 305 BC to 30 BC.
Ptolemy, a somatophylax, one of the seven bodyguards who served as Alexander the Great's generals and deputies, 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" (saviour). The Egyptians soon accepted the Ptolemies as the successors to the pharaohs of independent Egypt. Ptolemy's family ruled Egypt until the Roman conquest of 30 BC.
All the male rulers of the dynasty took the name Ptolemy. Ptolemaic queens, some of whom were the sisters of their husbands, were usually called Cleopatra, Arsinoe or Berenice. The most famous member of the line was the last queen, Cleopatra VII, known for her role in the Roman political battles between Julius Caesar and Pompey, and later between Octavian and Mark Antony. Her suicide at the conquest by Rome marked the end of Ptolemaic rule in Egypt.
The dates in brackets are regnal dates for the kings. They frequently ruled jointly with their wives, who were often also their sisters. Several queens exercised regal authority, but the most famous and successful was Cleopatra VII (51 BC-30 BC), with her two brothers and her son as successive nominal co-rulers. Several systems exist for numbering the later rulers; the one used here is the one most widely used by modern scholars. Dates are years of reign.
