The Cairo Geniza is a collection of Jewish manuscript fragments discovered in the late 19th century in a storeroom of the Ben Ezra Synagogue in Cairo, Egypt. This collection dates from the 9th to the 19th centuries and includes religious texts, legal documents, and personal letters, reflecting the daily life and culture of the Jewish community in the medieval Islamic world. The Geniza provides valuable insights into the history of Jewish life, trade, and scholarship in the Middle East. Scholars have studied these documents to understand the social, economic, and religious practices of the time, making the Cairo Geniza a crucial resource for historians and researchers.
