How did events in europe lead to revolution in the spanish colonies?

The Spanish colonies wanted to be independent for quite some time, and they just waited for suitable moment when the Spanish army would not be at its best, sot hat they can rebel and gain independence. The situation in Europe was going in the advantage of the Spanish colonies, as Spain was distracted by war, with Napoleon conquering pretty much everything on the continent. As most of the Spanish army was deployed to defend the homeland, the troops in the colonies were significantly weakened. The people in the colonies were monitoring the situation carefully, and when they saw that the Spanish army is weak enough, they attacked, managed to push them away, and gained independence one by one.

the correct answer is history and tradition.

china unilaterally claims the entire south china sea as sovereign territory, then builds artificial islands to bolster its claim. it suddenly activates an air defense identification zone over the east china sea, and threatens to down any aircraft that does not report its position. it builds roads into indian territory, then redraws the maps to show that it is actually chinese territory. the people's republic under president xi jinping is quickly becoming the bully of asia.
