Final answer:
The leading factors that contributed to the disintegration of the Spanish Empire were colonial grievances, economic exploitation, and prolonged conflicts and internal fragility.
Step-by-step explanation:
- Colonial grievances: The disruption of Spanish sovereignty and the reinstatement of pre-Napoleonic policies sparked immediate reactions in the colonies, leading to a search for independence.
- Economic exploitation: Spanish colonizers aimed to establish economies that exported wealth to Spain, depleting local environments and resources. This led to violence against Indigenous peoples who resisted these economic conditions.
- Prolonged conflicts and internal fragility: Spain experienced civil wars, factional politics, and internal instabilities. Losses of territories and nationalist revolts also contributed to the disintegration of the empire.
