Someone who was born in 100 and died in 44 lived i which historical period

Hi there, I think you are talking about Julius Caesar, Julius Caesar was a good man, he was a Roman statesman, general, and notable. Unfortunately, Julius Caesar was assassinated by Roman senators, Gaius Cassius Longinus and Marcus Junius Brutus stabbed Julius Caesar, along with a few other people. The death of Julius Caesar was tragic.

They lived in the period before christ was born, (Christianity) so they died before Jesus's time.
