Dinero - Sancho V crude bust

Sancho V — known as Sancho Ramírez — became king of Pamplona in 1063 and inherited Aragon in 1076 following the murder of his cousin Sancho IV of Peñafiel. His reign was defined by relentless Reconquista campaigning and a decisive pivot toward Rome, making Navarre-Aragon the first Iberian kingdom to formally adopt the Roman rite in place of the Mozarabic liturgy in 1071. The billon coinage of this period reflects the monetary realities of a frontier war economy — debased, practically struck, and circulated hard.

He died in 1094 during the siege of Huesca, killed by an arrow.
