When Father Miguel Hidalgo y Costilla rang his church bell in Dolores on September 16, 1810, issuing the Grito de Dolores, he ignited a revolution rooted in decades of structural injustice. His motivations — and those of the movement he sparked — were layered:
Spain's mercantilist policies choked New Spain's economy: trade restricted to Spanish ships, heavy taxes (alcabala, tribute), monopolies on mercury (essential for silver mining) and tobacco. Peasants and Indigenous communities bore the brunt.
Power rested with peninsulares (Spanish-born officials). Creoles (American-born Spaniards) — including educated elites like Hidalgo — were barred from top posts despite wealth and talent. This bred deep resentment.
The casta system legally ranked people by ancestry: peninsulares > creoles > mestizos > Indigenous > Africans. Creoles wanted equality with peninsulares; lower castes wanted liberation from all of them.
Hidalgo and fellow priests envisioned a sovereign Mexican nation — not just autonomy within empire, but full independence with just laws and equitable society.
Hidalgo read Rousseau, Voltaire, Montesquieu. Ideas of popular sovereignty, natural rights, and social contract circulated in Creole circles, legitimizing rebellion against tyranny.
Some intellectuals reclaiming pre-Hispanic identity (Aztec, Maya heritage) framed independence as restoration of a stolen civilization — a powerful symbolic narrative.
When Napoleon deposed Ferdinand VII, the Spanish monarchy collapsed. Colonies questioned: Who do we owe allegiance to now? This power vacuum turned simmering discontent into open revolt.
Hidalgo's call united these grievances into a mass movement — Indigenous, mestizo, and Creole — that, though he was captured and executed in 1811, ultimately birthed independent Mexico in 1821.
