Since the 1540s, the Crown had debased (devalued) the coinage, by reducing its silver and gold content, in order to make more money to fight wars against France. This resulted in inflation, as the value of the currency fell.
In spite of Elizabeth's careful management of Crown finances, there was limited reform. Parliamentary grants were raised locally, with many landowners acting as Lord Lieutenants and Justices of the Peace, pocketing some of the proceeds before the rest was sent to the Crown. This meant that ordinary people faced a heavier financial burden while the wealthy benefitted.
