Reply To: Tefilin On Chol hamoed In Eretz Yisroel

I am very aware of history as well as Sefardi minhagim. However while it is true to say that the Rosh “influenced” Sefardi minhagim as you write, R’ Yitzchak Karo writes that “all of Spain follows the Rosh for all dinim and all Issur v’Heter”. This statement is strange. Sefardi minhag follows the Rif, Rambam, Ramban and Rashba much more closely then the Rosh. The Beis Yosef in his introduction famously writes that he generally follows the majority of the 3 pillars of halacha: the Rif, Rambam and Rosh. Since the Rambam writes in his hakdama to Mishna Torah that he argues on the Rif in less then 8 places, the Rosh is usually outnumbered.
