The Treaty of Badajoz was signed in Badajoz on 16 February 1267 between King Alfonso X of Castile and King Afonso III of Portugal. Both signatories agreed to establish lines of mutual assistance and friendship. Based on the terms of the accord, Alfonso X surrendered all rights to the Kingdom of the Algarve, [1] which included the service of fifty knights. Moreover, he commanded his lieutenants to surrender the castles they controlled in Algarve to the Kingdom of Portugal. Despite all this, Alfonso X still continued to use the title king of the Algarve even though it was probably used in reference to the territory of Niebla. Both signatories agreed to use the Guadiana River from Elvas and Badajoz to Ayamonte on the Atlantic Ocean as the boundary line separating Castile and Portugal. This, in turn, forced Portugal to surrender Aracena, Moura, Serpa, and Aroche located east of the boundary line. North of the boundary line, Portugal was able to maintain Arronches, Alegrete, and Elvas, but was forced to capitulate Valencia de Alcántara and Marvão. [2]
The Treaty of Badajoz was succeeded by several other treaties as rivalry between Portugal and Castile persisted. Some of these treaties included those signed by Denis I and King Ferdinand of Castile in 1297 as well as the treaty signed in 1339. [3] Later, in 1801, Spain waged war against Portugal and invaded Badajoz. This event was concluded by a peace agreement, which was also called Treaty of Badajoz. This required Portugal to relinquish a number of territories, including the town of Olivença while the Guadiana River once again delineated the border between the two countries. [4]
Afonso III, or Affonso, Alfonso or Alphonso (Portuguese-Galician) or Alphonsus (Latin), the Boulonnais, King of Portugal was the first to use the title King of Portugal and the Algarve, from 1249. He was the second son of King Afonso II of Portugal and his wife, Urraca of Castile; he succeeded his brother, King Sancho II of Portugal, who died on 4 January 1248.
Ferdinand II was King of León and Galicia from 1157 to his death.
Alfonso X was the king of Castile, León and Galicia from 30 May 1252 until his death in 1284. During the election of 1257, a dissident faction chose him to be king of Germany on 1 April. He renounced his claim to Germany in 1275, and in creating an alliance with the Kingdom of England in 1254, his claim on the Duchy of Gascony as well.
The Guadiana River, or Odiana, is an international river defining a long stretch of the Portugal-Spain border, separating Extremadura and Andalucia (Spain) from Alentejo and Algarve (Portugal). The river's basin extends from the eastern portion of Extremadura to the southern provinces of the Algarve; the river and its tributaries flow from east to west, then south through Portugal to the border towns of Vila Real de Santo António (Portugal) and Ayamonte (Spain), where it flows into the Gulf of Cádiz. With a course that covers a distance of 829 kilometres (515 mi), it is the fourth-longest in the Iberian peninsula, and its hydrological basin extends over an area of approximately 68,000 square kilometres (26,000 sq mi).

The Mudéjar revolt of 1264–1266 was a rebellion by the Muslim populations (Mudéjares) in the Lower Andalusia and Murcia regions of the Crown of Castile. The rebellion was in response to Castile's policy of relocating Muslim populations from these regions and was partially instigated by Muhammad I of Granada. The rebels were aided by the independent Emirate of Granada, while the Castilians were allied with Aragon. Early in the uprising, the rebels managed to capture Murcia and Jerez, as well as several smaller towns, but were eventually defeated by the royal forces. Subsequently, Castile expelled the Muslim populations of the reconquered territories and encouraged Christians from elsewhere to settle their lands. Granada became a vassal of Castile and paid an annual tribute.
