Later, Abu Yusuf lands at Alcázar Seguir on January 19. This ending the first Marinid invasion in Al-Andalus (modern Spain). June – King Rudolf I declares war on his rival Ottokar II. After 6 months of campaigning, Ottokar surrenders all his lands (including Austria and Styria) except Bohemia and Moravia. Rudolf makes Vienna his capital, marking the beginning of the Habsburg Dynasty, which will last until 1918. England Spring – King Edward I (Longshanks) orders the people of Bayonne in Gascony (as part of the only English possessions in France) to provide Castile with warships "to resist the Saracens by sea", but he excuses himself from personal participation against the Marinid invasion in Spain because of his wars in Wales and his plan to lead a Crusade to the Holy Land.
