Yosef Karo רבי יוסף קארו

Author of the Shulchan Aruch — expelled from Spain as a child of four, he wandered through Portugal and Turkey and settled in Tzfat, where he headed its great beit din. No reception edge is drawn to him, and that absence is the point: his Beit Yosef openly reconstitutes the chain from BOOKS — deciding law by the majority of "the three pillars of hora'ah," Rif, Rambam, and Rosh. Here the map's gap honestly shows transmission becoming textual after expulsion and print.

ClaimEvidenceConfidenceSources
In the Beit Yosef's introduction he states his method: "since the three pillars of hora'ah upon whose rulings the house of Israel leans are the Rif, the Rambam, and the Rosh — I resolved that where two of them agree, the law follows them." Reception here is from texts, by design.
Deliberate no-edge decision: his childhood teachers (his father R' Ephraim, R' Yaakov Beirav later as colleague/ordainer in the renewed-semicha episode) are either unattested as formative or not teacher→student reception; the self-declared textual method is the honest picture.
rabbinic tradition ★★★★★
The Shulchan Aruch (published 1565), distilling the Beit Yosef into bare rulings on the Tur's structure, became — once joined by the Rema's glosses — the universal code of Jewish law. rabbinic ★★★★★
Tradition reports a maggid — a personified voice of the Mishnah — that visited him for decades, recorded in the diary published as Maggid Mesharim.
The diary's authenticity as Karo's is accepted by most scholars; the maggid itself is a claim of experience, graded as tradition.
tradition ★★☆☆☆
In the 1538 Tzfat attempt to renew classical semicha, Yaakov Berab ordained Yosef Karo. The revival rested on the Rambam's ruling that the sages of Eretz Yisrael could reinstitute ordination by consensus — a ruling the Rambam himself closed with "and the matter requires resolution" — and was contested by the Ralbach of Jerusalem. Karo used the ordination once, ordaining Moshe Alshich; the renewed line faded within a few generations.
semicha_from here is a revival edge (semicha: revival), not a claim of unbroken chain — the whole episode was a deliberate restart from the Rambam's consensus mechanism.
tradition external ★★★★☆
Yosef Karo was born in 1488, probably in Toledo, to the talmudist Ephraim Karo; after the Iberian expulsions his family settled in the Ottoman Empire, and after his father's death he was raised by his uncle Yitzchak Karo.
His birth in Toledo is probable rather than certain; Portugal has also been proposed.
external reconstruction ★★★★☆
Karo married at least three times. Three sons survived him: Shlomo, Yehudah, and a third son possibly named Yitzchak; two other sons and a daughter died while he was living in the Ottoman Empire.
The personal names of his wives are not supplied; they are identified through their fathers.
external ★★★★☆
Karo headed a large yeshiva in Safed; one traveler reported approximately two hundred students attending his lectures, and Karo received legal questions from communities throughout the Diaspora.
The student count comes from a traveler's report and is not independently verifiable.
external ★★★★☆
He began writing Beit Yosef in 1522 and completed it in Safed in 1542. He also wrote Shulchan Arukh, first printed in Venice in 1564–1565, and Kesef Mishneh, printed in 1574–1575.
These dates concern composition and first publication, not later editions.
external ★★★★★
Karo died in Safed on 13 Nisan 5335 at approximately age eighty- seven and was buried in Safed's old Jewish cemetery, where a grave identified as his remains visible.
The burial tradition is longstanding, but the remains have not been subjected to archaeological authentication.
