What Is a Siddur?

(order), reflecting the siddur's function: ordering and organizing the prayers for worship.

Historical Development

Temple Era

During the Temple period, worship centered on sacrifices rather than fixed texts. Prayers existed but weren't standardized.

Post-Temple Standardization

After the Temple's destruction (70 CE), the Men of the Great Assembly and later rabbis formulated standard prayers to replace sacrificial worship.

First Siddurim

The earliest written prayer books appeared in the 9th century. The Siddur of Rav Amram Gaon and the Siddur of Rav Saadia Gaon are landmark compilations.
