Julius Caesar (100 BC – 44 BC) was a Roman military and political leader, one of the most influential men in world history, and dictator for life of Rome. He played a critical role in the transformation of the Roman Republic into the Roman Empire. His conquest of Gaul extended the Roman world all the way to the Atlantic Ocean, and he was also responsible for the first Roman invasion of Britannia in 55 BC. Caesar was widely considered to be one of the foremost military geniuses of his time, as well as a brilliant politician and one of the ancient world's strongest leaders. In 42 BC, two years after his assassination, the Roman Senate officially sanctified him as one of the Roman deities.
Caesar also conducted a love affair and political alliance with Cleopatra, which has been the fodder for many plays and films. Caesar himself became the title figure of William Shakespeare's play Julius Caesar.
