Wer heiratete Margarete von Navarra (Sizilien)?

Margarete von Navarra (italienisch: Margherita di Navarra; * 1128; † 31. Juli 1183 in Palermo) war als Gattin von Wilhelm I. von 1154–66 Königin von Sizilien sowie von 1166 bis 1171 anstelle ihres minderjährigen Sohns Wilhelm II. die Regentin Siziliens.

William I (1120 or 1121 – 7 May 1166), called the Bad or the Wicked (Sicilian: Gugghiermu lu Malu), was the second king of Sicily, ruling from his father's death in 1154 to his own in 1166. He was the fourth son of Roger II and Elvira of Castile.

William's title "the Bad" seems little merited and expresses the bias of the historian Hugo Falcandus and the baronial class against the king and the official class by whom he was guided.
