Rashba
1235 CE–1310 CE · Rishonim · Barcelona
Rabbi Shlomo ben Avraham ibn Aderet (1235–1310), known by the acronym Rashba, was the foremost halachic authority of his generation — so revered that he was called 'El Rab d'España,' the Rabbi of Spain. Born in Barcelona, he studied under Nachmanides (the Ramban) and Rabbeinu Yonah Gerondi, and served as rabbi of the city's main synagogue for some fifty years, his court a court of appeal for the whole Jewish world.
His more than three thousand responsa — fielding questions from Spain, Portugal, France, Germany, Italy, and Asia Minor — are an unmatched window into medieval Jewish life and law, and his Talmudic novellae (Chiddushei HaRashba) together with his Torat HaBayit on the laws of kashrut and the home remain pillars of halachic study. Among his many students were the Ritva (Yom Tov of Seville) and Rabbeinu Bachya ben Asher.
The Rashba also stood at the center of his era's great struggles. In 1305 he and the Barcelona rabbinate proclaimed a ban forbidding the study of Greek philosophy and natural science before the age of thirty (medicine excepted) — a controversial measure against the rationalist excesses he saw spreading from Provence. He defended Judaism against the Dominican polemic of Raymond Martini and against Muslim critics, and opposed alike the rationalist philosophers and the messianic claims of figures such as Abraham Abulafia. He remained the defining voice of Spanish Jewry until his death in Barcelona in 1310.

Barcelona in this era
Barcelona in the Rishonic era was a bustling Mediterranean port city ruled first by Muslim emirs and then, from the eleventh century onward, by Christian counts of Catalonia whose authority grew as the Reconquista advanced southward. The Jewish community there flourished particularly from the twelfth century through the early fifteenth, enjoying relative security and prosperity under Christian rule—merchants and physicians rose to prominence, and the call (aljama) maintained its own courts and governance. The city became a notable center of philosophical and scientific learning, where rabbinic scholars engaged with Aristotelian thought transmitted through Arabic sources, debating questions of faith and reason with an intensity that marked the Spanish-Jewish intellectual ferment. The Call, Barcelona's Jewish quarter nestled near the cathedral, grew dense with synagogues, schools, and the homes of both wealthy traders and learned families; in this narrow warren of stone streets, Talmudic study flourished alongside medicine, astronomy, and mysticism. By the late fourteenth century, however, the community endured violent upheavals—anti-Jewish riots swept the city in 1391—though learning persisted even as pressure mounted, until the final Spanish expulsion of 1492 scattered its scholars across the Mediterranean and beyond.
