After success in war makes Caesar a rising star, escalating tension between Rome's two most powerful men creates an opportunity for advancement.

Caesar's wealth grows as one-third of the triumvirate, but his brutal tactics make enemies -- forcing him to remake his image as a military conqueror.

Caesar's hard-won victory over Gaul endears him to the Roman people but leads to a military showdown with the Senate and his former ally, Pompey.

After chasing Pompey to Alexandria, Caesar is victorious in the war, then swiftly makes a powerful new ally and lover in Egypt's ruler, Cleopatra.

His reforms win public adoration, but Caesar's imperial ambitions antagonize the Senate and ill health undermines his authority, sparking a conspiracy.

After the mysterious death of his popular father, young Caligula grows up in the uncertain shadow of his tyrannical emperor and uncle, Tiberius.

The death of Tiberius vaults Caligula to power as Rome's new emperor, a role at which he initially excels -- until an illness unhinges his mind.

Vulnerable without an heir, Caligula decides to secure the throne with a child of royal blood by embroiling himself in affairs with his three sisters.

Caligula's increasing paranoia and debauchery lead to ruinous bloodshed and spending as Rome, the Senate and even former allies turn against him.
