The emperor of Rome when Jesus died was Tiberius. Tiberius was the second Roman emperor, ruling from 14 AD to 37 AD. According to historical records and the New Testament, Jesus was crucified during the reign of Tiberius, around 30-33 AD. Tiberius’s reign is noted for its relative stability, but he was also known for his reclusive and sometimes harsh rule. The crucifixion of Jesus is a significant event in Christian theology, marking the culmination of Jesus’s earthly ministry and the foundation of Christian belief in his resurrection.
