Europe

• May 20 – Diet of Pentecost: Emperor Frederick I (Barbarossa) organises a conference in Mainz. During the diet Frederick negotiates with Henry the Lion about an anti-French alliance with England.
• June 15 – Battle of Fimreite: King Sverre of Norway defeats and kills his rival, Magnus V (Erlingsson) near Fimreite. Sverre takes the throne and becomes sole ruler of Norway (until 1202).
• June – July – Almohad forces reconquer the Alentejo (except for Évora), and besiege Lisbon on land and blockade the port with their navy. A Portuguese soldier manages to swim to the largest ship of the fleet and to sink it. This ship was so tall, it would have allowed the Muslims to easily reach the walls of the city. The next day, the Almohads have to retreat, taking with them a number of civilian captives.
• Siege of Santarém: Almohad forces under Caliph Abu Yaqub Yusuf march towards Badajoz and besiege Santarém, which is defended by King Afonso I (the Conqueror). Upon hearing of Abu Yusuf's attack, Ferdinand II of León marches his army to Santarém to support his father-in-law, Afonso. Abu Yusuf, in an attempt to break the siege, is wounded by a crossbow bolt and dies on July 29.

• May – Berber forces under Ali Banu Ghaniya seize by surprise the Almohad cities of Algiers, Béjaïa and Constantine. While he is away from his base in Mallorca, one of his brothers, Muhammad, takes control of the island and calls in the Almohads, who intend to capture Mallorca for themselves. Banu Ghaniya arrives just in time, to defeat the Almohads and recaptures the island.
• August 10 – Abu Yusuf Yaqub al-Mansur is proclaimed the new caliph of the Almohad Caliphate, after his father Abu Yaqub Yusuf is killed in Portugal.
