Frederick the Simple, born on December fourth, thirteen forty-two in Catania, was a significant figure in Sicilian history, reigning as King of Sicily from thirteen fifty-five until his death in thirteen seventy-seven. He was the second son of Peter II of Sicily and Elisabeth of Carinthia, and he ascended to the throne following the death of his elder brother, Louis. His reign began under the regency of his sister, Euphemia of Sicily, during a tumultuous period marked by the influence of powerful Sicilian barons, particularly Artale I Alagona.
The early years of Frederick's rule were overshadowed by the devastating effects of the Black Death, which had claimed the life of his predecessor. Despite these challenges, Frederick managed to navigate the complexities of his reign, including a notable decree on December twenty-fifth, thirteen sixty-nine, which mandated that all Jews wear a badge to signify their heritage. This badge was to be made of red material, prominently displayed, reflecting the social tensions of the time.
In thirteen seventy-two, Frederick achieved a diplomatic milestone by reaching peace terms with Naples and Pope Gregory XI, earning the title of tributary King of 'Trinacria.' His lineage also held significance; after the death of his mother's cousin, Margaret of Tyrol, Frederick became the last descendant of the House of Gorizia-Tyrol, a dynasty that once ruled over a vast territory in the Eastern Alps. However, due to the political strife within his own realm, he did not pursue claims to these territories, which ultimately fell to the Habsburgs.
