The main cause of the **Mexican War of Independence** was the growing discontent among **Mexican** citizens against **Spanish colonial rule**. Economic inequalities, social injustices, and a desire for political autonomy spurred revolutionary ideas. Influenced by Enlightenment principles and the successes of other independence movements, figures like **Miguel Hidalgo** ignited the quest for self-governance starting in 1810. The conflict was also fueled by social stratification, with Creoles seeking equal rights with **Peninsulares**. Over the ensuing years, this struggle culminated in a prolonged war, resulting in Mexico gaining independence from Spain in **1821**.
