12CE

12 CE, written with CE standing for Common Era, is the 12th year of the Common Era. In the Julian calendar, it was a leap year, so February had 29 days. The year falls in the 1st century CE, a period traditionally associated with the early Roman Empire under Emperor Augustus and the consolidation of Roman rule across the Mediterranean.

The historical record for the specific events of 12 CE is limited; most information about this era comes from Roman inscriptions, genealogies, and later historians who place events in broader year ranges rather than single calendar years. Across other regions, contemporary sources are even sparser, and many regional histories from this period have relied on archaeological evidence to reconstruct daily life, governance, and trade patterns.

The year is not widely cited for a major standalone turning point in surviving sources, but it sits within the broader patterns of Roman expansion, imperial administration, and cultural exchange characteristic of the early first century. The use of CE notation reflects modern dating conventions; the year corresponds roughly to the late Augustus period of the Roman state.
