Treaty of Sahagún (1158)
The Treaty of Sahagún ended a state of war between the Castile and León, establishing pacem et ueram amiciciam (peace and true friendship) between their respective monarchs, Sancho III and Ferdinand II, who called themselves boni fratres et boni amici (good brothers and good friends). It was signed at the monastery of Sahagún on 23 May 1158.[1]
On the death of
The Treaty of Sahagún put an end to the quarrel. It stipulated that Sancho should return the seized lands to his brother, but also that they should be held in fidelitate (in fealty) from Ferdinand by three counts: Ponce Giraldo de Cabrera, Osorio Martínez, and Ponce de Minerva. If either party ignored his treaty obligations the lands reverted to the other after a year, save those bestowed on Osorio, who secured hereditary rights. The other counts could only be succeeded, in the event of death, by their sons or by certain other noblemen stipulated by the treaty.[4]
Sancho and Ferdinand also agreed to aid one another militarily against any enemy save their uncle,
Sancho III died on 31 August and Ferdinand promptly made a claim on Castile and occupied some territories, while the Castilian aristocracy descended into a civil war for control of Sancho's heir, Alfonso VIII.[5]
