And it came to pass in those days, that there went out a decree from Caesar Augustus, that all the world should be taxed.
Note 1 at Lu 2:1: Caesar was a title used for Roman emperors much as we use the title President today. This Caesar was called Augustus, but his actual name was Gaius Octavius. He succeeded Julius Caesar in 27 B.C. and reigned until A.D. 14. His successor was Tiberius Caesar (Lu 3:1), his stepson (see notes 1-2 at Lu 3:1).
