Sephardic Jews, also known as Sephardi Jews or Sephardim, and rarely as Iberian Peninsular Jews, are a Jewish diaspora population associated with the historic Jewish communities of the Iberian Peninsula (Spain and Portugal) and their descendants. The term "Sephardic" comes from Sepharad, the Hebrew word for Iberia. These communities flourished for centuries in Iberia until they were expelled in the late 15th century. Over time, "Sephardic" has also come to refer more broadly to Jews, particularly in the Middle East and North Africa, who adopted Sephardic religious customs and legal traditions, often due to the influence of exiles. In some cases, Ashkenazi Jews who settled in Sephardic communities and adopted their liturgy are also included under this term. Today, Sephardic Jews form a major component of the global Jewish population, with the largest population living in Israel.
The earliest documented Jewish presence in the Iberian Peninsula dates to the Roman period, beginning in the first centuries CE. After facing persecution under the Pagan and later Christian Visigothic Kingdom, Jewish communities flourished for centuries under Muslim rule in Al-Andalus following the Umayyad conquest (711–720s), a period often seen as a golden age. Their status declined under the radical Almoravid and Almohad dynasties and during the Christian Reconquista. In 1391, anti-Jewish riots in Castile and Aragon led to massacres and mass forced conversions. In 1492, the Alhambra Decree by the Catholic Monarchs expelled Jews from Spain, and in 1496, King Manuel I of Portugal issued a similar edict. These events led to migrations, forced conversions, and executions. Sephardic Jews dispersed widely: many found refuge in the Ottoman Empire, settling in cities such as Istanbul, Salonica, and İzmir; others relocated to North African centers like Fez, Algiers, and Tunis; Italian ports including Venice and Livorno; and parts of the Balkans, the Levant (notably Safed), and the Netherlands (notably Amsterdam). Smaller communities also emerged in France, England, and the Americas, where Sephardim often played key roles in commerce and diplomacy.
