Alexander Jannaeus, second king of the Hasmonean dynasty (103–76 BCE), governed Judea through aggressive military campaigns and authoritarian rule, characterized by persistent conflict both internationally and within his kingdom. His territorial acquisitions, such as coastal cities and areas in Transjordan, were counterbalanced by internal discord, especially with the Pharisees, whom he oppressed for resisting his religious and political agenda.
Historical records, including Josephus’s Antiquities of the Jews, emphasize the turmoil of his reign, while contemporaries like William Fairweather observed his alignment with the Sadducees and the harsh quelling of uprisings. His reign remains a crucial, disputed period in Hasmonean history, influencing Judea’s divided political and religious environment.
