​Dates in Ancient History

In ancient history, years are written with abbreviations.

A year followed by B.C. refers to the number of years before the birth of Christ.

A year preceded by A.D. refers to the number of years after the birth of Christ.

Historians also use B.C.E. (Before Common Era) and C.E. (Common Era) for these periods.

PSA: the year AD 1 happened immediately after 1 BC. There is no year 0!

Bias and Reliability

All sources have bias. It is the historian's job to identify bias and see past it to the "truth."

All sources must be tested for reliability. Can your information be trusted? Should it be taken with a "grain of salt" or ignored completely?

Bias: preference for one side/view point over another

Reliability: trustworthy, accurate
