With the fall of Rome and the fragmentation of Europe into feudal kingdoms, each monarch controlled their own mint. The temptation to debase was structural: a king who recalled all the silver coins in circulation, melted them, and re-struck them with less silver per coin kept the difference as seigniorage. Across 500 years, nearly every European kingdom did this at least once. The most spectacular was Henry VIII's Great Debasement of 1544 to 1551, which cut the silver content of the English shilling from 92.5 percent to 25 percent in seven years.
