Sancho I of Portugal
In 1189, King Sancho I of Portugal conquered Silves, one of the most prosperous cities in Al-Andalus, aligned at the time with the Almohad Caliphate. Portuguese control over Silves would be short, with the Almohads conquering the city again in 1191 in a massive counter-attack led by Abu Yusuf Yaqub al-Mansur the Almohad Caliph in person.
