The relationship between Judaism and politics is a historically complex subject, and has evolved over time concurrently with both changes within Jewish society and religious practice, and changes in the general society of places where Jewish people live. In particular, Jewish political thought can be split into four major eras: biblical (prior to Roman rule), rabbinic (from roughly the 100 BCE to 600 CE), medieval (from roughly 600 CE to 1800 CE), and modern (18th century to the present day).
