Bibas was born in Gibraltar to Sephardi Jews who were descendants of Jews expelled from Spain and had settled in North Africa. One of his maternal ancestors was Chaim ibn Attar. His father came from a line of Rabbis in Tétouan that emigrated to Gibraltar in 1859 after a pogrom against the Jews that followed the invasion of the city by Spain. Bibas studied as a child in Gibraltar and after the death of his father he moved to Livorno to live with his grandfather. Livorno had a very prestigious and educated Jewish community. Bibas received in Livorno most of his Jewish and secular education, including his title as a physician. He then returned to Gibraltar where he established himself as the Rosh yeshiva. His Yeshiva was attended by students from England, Italy and North Africa. In 1810 he came to London, where he met with the famous Jewish activist and philanthropist Sir Moses Montefiore. Rabbi Yehuda Bibas was fluent in English, Italian, Spanish and Hebrew, and he was a rabbi and a physician. In 1831, Bibas was appointed as the Chief Rabbi of Corfu.
By the years 1839-1840, Bibas undertook a journey in Europe. While visiting many Jewish communities, he called upon the Jews to make Aliyah to Palestine and settle there. He was one of the first Rabbis to do so. In the same year, he met with Judah Alkalai, who became his student. Bibas's plan was to encourage Jews from all over the world to come to Palestine, conquer the land from the Ottomans, and create a Jewish society there. During some of his visits to London, he cooperated with Moses Montefiore on many subjects.
Aliyah and death
By 1852, one year after his wife died, Bibas made Aliyah to Palestine, and was welcomed by his students in Jaffa. Later he went to Hebron where he built his extensive library. He died two months after his arrival to Palestine and was buried in the Old Jewish Cemetery in Hebron.
