Emperor Nero was born on 15 December 37 in Antium, near Rome. He was the only son of Gnaeus Domitius Ahenobarbus and Agrippina the Younger, sister of Emperor Caligula. Caligula was murdered on 24 January 41, and Claudius, Caligula's uncle, became emperor. Claudius died in 54 and Nero was established as Emperor. Over the course of his reign, Nero often made rulings that pleased the lower class. In 64, Rome burned. Nero enacted a public relief effort as well as significant reconstruction. A number of other major construction projects occurred in Nero's late reign. The cost to rebuild Rome was immense, leaving the provinces ruined. In March 68 the governors of Gallia Lugdunensis and Hispania Tarraconensis rebelled. When support for the rebellion grew, Nero fled Rome.
