A decree went out from Caesar Augustus to take a census of all the inhabited earth (Luke 2:1).
As the first Roman emperor, Caesar Augustus reigned from 27 BC to AD 14. He was a superb organizer, demonstrated (among other things) by the multiple censuses he took while in power. But while this particular census must have served a needed administrative function for him, it also served a more important purpose; through it, God providentially brought Joseph and Mary to Bethlehem during the time Jesus was to be born, fulfilling the prophecy of Micah 5:2.
