Answer
Godoy's downfall was triggered by the Tumult of Aranjuez, a popular uprising that took place in March 1808 in Aranjuez, Spain. The revolt was fueled by public discontent with the unpopular Godoy, who was widely perceived as corrupt and incompetent. The uprising forced King Charles IV to abdicate in favor of his son, Ferdinand VII, and led to Godoy's arrest and imprisonment.
