Who was the Roman Emperor when Christ was born?
Jesus Christ lived His entire human life under the Roman empire, the first half under Caesar Augustus (Luke 2:1), who reigned when He was born in Bethlehem, the second half under Tiberius (Luke 3:1), when He still lived at Nazareth in Galilee, before moving to Capernaum on the shore of the Sea of Galilee, until His Crucifixion at Calvary in Jerusalem.
