The 0s began on January 1, AD 1 and ended on December 31, AD 9, covering the first nine years of the Common Era. It is one of two "0-to-9" decade-like timespans that contain nine years, along with the 0s BC.
Literary works from the 0s include works from the ancient Roman poet Ovid; the Ars Amatoria, an instructional elegy series in three books, Metamorphoses, a poem which chronicles the history of the world from its creation to the deification of Julius Caesar within a loose mythico-historical framework, and Ibis, a curse poem written during his years in exile across the Black Sea for an offense against Augustus. Nicolaus of Damascus wrote the 15-volume History of the World.
Estimates for the world population by AD 1 range from 150 to 300 million. A census was concluded in China in AD 2: final numbers showed a population of nearly 60 million (59,594,978 people in slightly more than 12 million households). The census is one of the most accurate surveys in Chinese history. Dionysius Exiguus assigned Jesus's birth date in AD 1, in his anno Domini era according to at least one scholar. However, most scholars think Dionysius placed the birth of Jesus in the previous year, 1 BC. Furthermore, most modern scholars do not consider Dionysius' calculations authoritative, placing the event several years earlier (see Chronology of Jesus).

Gaius Caesar meets with Phraates V, the king of Parthia, on the Euphrates. Rather than invade the Parthians, Gaius Caesar concludes peace with them; Parthia recognizes Roman claims to Armenia.[8]
Juba IIofMauretania joins Gaius Caesar in Armenia as a military advisor. It is during this period that he meets Glaphyra, a Cappadocian princess and the former wife of Alexandros of Judea, a brother of Herod Archelaus, ethnarch of Judea, and becomes enamoured with her.[9]
Wang Mang begins a program of personal aggrandizement, restoring marquess titles to past imperial princes and introducing a pension system for retired officials. Restrictions are placed on the Emperor's mother, Consort Wei and members of the Wei Clan.[8]
The first census is concluded in China after having begun the year before: final numbers show a population of nearly 60 million (59,594,978 people in slightly more than 12 million households). The census is one of the most accurate surveys in Chinese history.[8]
Wang Mang foils a plot by his son, Wang Yu, his brother-in-law, Lu Kuan, and the Wei clan to oust him from the regent's position. Wang Yu and Lu Kuan are killed in the purge that follows.[11]
Emperor Augustus summons Tiberius to Rome, and names him his heir and future emperor. At the same time, Agrippa Postumus, the last son of Marcus Vipsanius Agrippa, is also adopted and named as Augustus' heir.
A pact of non-aggression and friendship is signed between the Roman Empire, represented by Tiberius, and the German tribe the Cherusci, represented by their King Segimer. Arminius and Flavus, sons of Segimer, are brought into the Roman army as leaders of the auxiliary troops.
Due to a catastrophic fire in Rome, the barracks system - the vigiles, initially manned only by freedmen - is created by the PrincepsAugustus to allow quicker response to outbreaks of fire in the city.[13]
Due to a food shortage in Rome, Augustus doubles the grain rations distributed to the people, sends away his slave retinue, and places the senate in recess indefinitely.[14]
The PrincepsAugustus sets up a treasury, the aerarium militare (170 million sestertii), with the specific purpose of paying bonuses to retiring legion veterans. This is financed by a 5% tax on inheritances, a system said to have been suggested in Julius Caesar's memoirs.[15]
Quirinius conducts a census in Judea (according to Josephus), which results in a revolt in the province, led by Judas of Galilee, and supported by the Pharisee Zadok. The revolt is repressed, and the rebels are crucified, but it results in the birth of the Zealot movement, the members of which regard the God of Judaism as their only master.
Candidates for government office must take civil-service examinations.
The imperial Liu clan suspects the intentions of Wang Mang and foment agrarian rebellions during the course of Ruzi Ying's reign. The first of these is led by Liu Chong, Marquess of Ang-Zong (a/k/a Marquis of An-chung), with a small force starting in May or June.[25]
Publius Quinctilius Varus is appointed governor of Germania, charged with organizing Germania between the Rhine and Elbe rivers. He carries out a census, devises tributes and recruits soldiers, all of which creates dissension among the Germanic tribes.
Zhai Yi, Governor of the Commandery of Dong (modern Puyang, Henan) declares Liu Zin, Marquess of Yang Xiang (modern Tai'an, Shandong), emperor. This proves to be the largest of the rebellions against Emperor Ruzi of Han.
Wang Mang puts down the rebellion during the winter. Zhai is captured and executed while Liu Xin escapes.
Wang Mang crushes a rebellion by Chai I, and on the winter solstice (which has been dated January 10 of the following year) officially assumes the title emperor, establishing the short-lived Xin dynasty.[25]
After completing Metamorphoses, Ovid begins the Fasti (Festivals), 6 books that detail the first 6 months of the year and provide valuable insights into the Roman calendar.
Empress Wang is given the title of Duchess Dowager of Ding'an, while Ruzi Ying, the former Emperor of Han, becomes the Duke of Ding'an. Ruzi Ying is placed under house arrest.
The Bellum Batonianum (Great Illyrian Revolt) in Dalmatia is suppressed.
First record of the subdivision of the province of Illyricum into lower (Pannonia) and upper (Dalmatia) regions.
In order to increase the number of marriages, and ultimately the population, the Lex Papia Poppaea is adopted in Italy. This law prohibits celibacy and childless relationships.
Roman finances become strained following the Danubian insurrection and the Battle of the Teutoburg Forest, resulting in the levying of two new taxes: five percent on inheritances, and one percent on sales.
By AD 1, the Roman Empire had been expanding its territories and exerting influence throughout Europe, including regions bordering the Rhine River. The Romans sought to consolidate their control over Germanic territories east of the Rhine and integrate them into the empire. Between 2 BC and AD 4, Vinicius commanded five legions in Germany, successfully leading them in the "vast war" against Germanic tribes. He was awarded the ornamenta triumphalia upon his return to Rome. In AD 4, Tiberius took command and waged campaigns in northern Germany, conquering several tribes and establishing alliances. The Cherusci tribe, including the influential Arminius, became friends with Rome. Tiberius built a winter base on the Lippe to monitor the Cherusci. By AD 6, most German tribes were pacified, and Rome planned an attack on the Marcomanni but made peace instead. Varus replaced Tiberius and imposed civic changes, but Arminius incited a revolt. In AD 9, Varus fell into an ambush by Arminius, suffering a devastating defeat as Roman forces were surrounded and overwhelmed. Varus took his own life, while a few survivors managed to return to Roman quarters.
