Sahagún, on the pilgrim road across the Tierra de Campos, is the richest abbey of León, Cluniac since the 1080s and the burial church of Alfonso VI.
Its abbot is lord of the town that grew at its gates. About 1080 Alfonso VI gave the settlers, many of them Frankish merchants and craftsmen, a fuero with exemptions and guarantees while confirming the monastery's lordship. When a later abbot doctored the text (dating it 1085) and tightened the abbey's monopolies, such as the rule that all must bake bread in the monastery's ovens, the burgesses rose in revolt during the civil wars of Urraca and Alfonso the Battler.
Alfonso VII confirmed a revised fuero in the middle of the twelfth century. The town sits close to the Castile-León border, which was fought over in 1196-1197.
