Overview

AD 22 (22 CE) is the twenty‑second year of the first century of the Common Era. In the Roman system of the time it was identified as the Year of the Consulship of Agrippa and Galba; in later medieval chronology it came to be called 22 AD or 22 CE. The year is recorded in surviving sources only sporadically, and it sits within the broader era of the early Roman Empire under Emperor Tiberius.

Calendar and dating

According to retrospective reconstruction of the Julian calendar, AD 22 was a common year beginning on Thursday. The Julian calendar, instituted by Julius Caesar, had a regular cycle of a leap day every four years and remained in widespread use in Europe into the late medieval period. Romans typically named years by the two serving consuls rather than by numerical era; Year of the Consulship of Agrippa and Galba is an example of this practice.

Political context in Rome

In Rome the emperor Tiberius continued to exercise central authority while republican offices such as the consulship remained important ceremonial and administrative posts. The consular year name provided a convenient chronological label for official records and inscriptions. The personalities and careers of consuls mattered for Roman politics and senatorial prestige, even when ultimate power lay with the emperor.

Wider world

Beyond Rome, the first century was a time of active states and shifting power across Eurasia. In China, the Eastern Han dynasty governed large regions of East Asia, and various kingdoms and polities operated across South Asia, the Near East, and northern Africa. Records for any single year can be fragmentary, so historians often place events within broader multi‑year trends rather than attributing many precise incidents to AD 22 alone.

Sources and significance

Our knowledge of AD 22 derives from later historians, inscriptions, and chronological compilations that preserve names of magistrates and significant happenings. Ancient annalists and later chroniclers converted Roman consular dating into chronological tables; modern scholars use these sources plus astronomical and archaeological data to align calendars. For calendar details see the 1st century studies and treatments of the Julian calendar and weekday reconstructions.

Notable facts and distinctions

  • The year is conventionally labelled 22 AD (Anno Domini) in modern Western chronology.
  • Romans referred to years by consuls—here by Agrippa and Galba—rather than by a continuous era; this custom persisted for centuries.
  • Reconstruction of weekdays for ancient years relies on the mechanics of the Julian calendar and later scholarly correlation.

Because surviving accounts are limited, AD 22 is best understood as part of larger political and social developments of the early first century rather than as a year distinguished by widely reported singular events.
