Egyptian law did not allow their queen to rule without a king from the Ptolemy family, so Cleopatra married another brother, this one named Ptolemy XIV, though she was in love with Caesar.
Caesar and Cleopatra spent the next several months sailing along the Nile, where Caesar observed how the Egyptian people worshipped Cleopatra as a pharaoh. Caesar was a very powerful general who conquered many lands, but he knew that becoming a god was something he could never achieve.
Soon after Caesar returned to Rome in 46BCE, Cleopatra and their newborn son, Caesarion, came to live in Rome. Caesar was so popular with the Roman people they named him dictator. A dictator is a ruler with complete power. Cleopatra, however, was less popular with the Romans, having enraged them by calling herself the “new Isis.”
Caesar was murdered in 44BCE, so Cleopatra left Rome and returned to Egypt. Shortly after, Ptolemy XIV was mysteriously poisoned.
