Events

January 22 – Sultan Muhammad I (or Ibn al-Ahmar) suffers fatal injuries after falling from his horse near the city of Granada during a minor military expedition. He is succeeded by his son Muhammad II, who becomes ruler of the Emirate of Granada. Muhammad enters negotiations with King Alfonso X ("the Wise") to make peace with Castile, but he refuses to grant a truce to the Banu governors (arraeces) of Málaga and Guadix in Andalusia.^[1]
Autumn – Sultan Muhammad II of Granada sends an embassy to the court of Alfonso X in Seville, where it is received with honour. Alfonso agrees to Granada's demands, to end his support for the Banu Ashqilula, in exchange for the promise that Muhammad becomes Alfonso's vassal. Muhammad pays him 450,000 maravedis each year in tribute and grants the Banu rebels a truce for two years.^[2]
October 1 – Rudolf I is elected King of Germany over the rival candidate Ottokar II, king of Bohemia, ending the Great Interregnum. He is the first of many Habsburgs to hold the throne and is crowned in Aachen Cathedral, on October 24. Ottokar refuses to acknowledge Rudolf as the new ruler and is placed under the imperial ban, leading to the outbreak of war in 1276.^[3]
