The first major and most violent persecution in Islamic Spain was the 1066 Granada massacre, which occurred on 30 December, when a Muslim mob stormed the royal palace in Granada, crucified Jewish vizier Joseph ibn Naghrela and massacred most of the Jewish population of the city after rumors spread that the powerful vizier was plotting to kill the weak-minded and drunk King Badis ibn Habus. According to the 1906 Jewish Encyclopedia, "More than 1,500 Jewish families, numbering 4,000 persons, fell in one day, a number contested by some historians who deem it to be an example of "the usual hyperbole in numerical estimates, with which history abounds." The decline of the Golden Age began before the completion of the Christian "Reconquista", with the penetration and influence of the Almoravides, and then the Almohads, from North Africa. These more intolerant sects abhorred the liberality of the Islamic culture of "al-Andalus", including the position of authority some "dhimmis" held over Muslims. When the Almohads gave the Jews a choice of either death or conversion to Islam, many Jews emigrated. Some, such as the family of Maimonides, fled south and east to the more tolerant Muslim lands, while others went northward to settle in the growing Christian kingdoms.
