The 1st century was that century that lasted from 1 to 100 according the Gregorian calendar. It is considered part of the Classical era, epoch, or historical period
During this period Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian Dynasty, which had been foundered by Augustus came to an end with the death of Nero in 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, 9th Roman emperor, and founder of the Flavian Dynasty.
