Carlos III of Navarre — "el Noble" — came to the throne in 1387 following years of civil conflict between his father Carlos II and the French crown. The half-grueso belongs to the early years of his reign, when the Navarrese monetary system was being stabilized after decades of debasement under Carlos II, whose chronic underfunding of the coinage had badly eroded public trust in the currency.
Navarre's mint at Pamplona operated under close royal supervision during this period, partly because Carlos II had repeatedly pledged mint revenues as collateral to foreign creditors.
