Marc Antony was Caesar's most loyal supporter and close adviser. After
Caesar's assassination Marc Antony was forced to flee. He later fell into
a partner ship with Octavian (Caesar's heir). This was a good deal until
Marc fell in love with Cleopatra . The partner
ship ran out and Octavian declared war on Antony. Octavian won, though
it was close,and to make a long story short, Antony commited suicide, then
Cleopatra, and Octavian was named emperor.
This is a picture of Antony and Octavian on coins from the time of
their power.
