Flavius Claudius Julianus, also known as Julian the Apostate, was a Roman emperor who reigned from 361 to 363. He was known for his attempts to revive traditional Roman religious practices and his opposition to Christianity. Julian was a philosopher and writer, and he sought to restore the pagan faith and culture that had been suppressed during the reign of his predecessors. He also implemented various reforms during his short reign. Julian's reign came to an end when he died in battle against the Sassanid Empire. His efforts to revive paganism and his complex relationship with Christianity have made him a figure of interest in historical and religious studies.
