After the peace of Tuy, Afonso Henriques temporarily turned his attention to the Muslim threat in the south. In 1139 he struck deep into the heart of Al Andalus and defeated a Muslim army at Ourique, a place in the Alentejo. After this battle, Afonso Henriques began to be referred to in documents as king. In 1140 he renewed his claim on southern Galicia, which he invaded. This again sparked a reaction by Alfonso VII who, in return, marched on Portugal. The two armies met at Arcos de Valdevez and engaged in a joust won by the Portuguese knights. Afonso Henriques's self-proclamation as king was finally recognized in 1143 at the Conference of Samora when Alfonso VII recognized him as such, although, because he was an emperor, Alfonso VII still considered Afonso Henriques his vassal.
