Map of Asia Minor (89 BC)

Year 89 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Strabo and Cato (or, less frequently, year 665 Ab urbe condita) and the Fourth Year of Zhenghe. The denomination 89 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
