Why did Napoleon was justified in fighting for independence from Spain?

Napoleon was justified in fighting for independence from Spain primarily due to the widespread desire for liberation from oppressive colonial rule and the promotion of national sovereignty. His military campaigns aimed to spread revolutionary ideals of freedom and equality, challenging the autocratic governance of the Spanish monarchy. Additionally, the political instability in Spain, exacerbated by the Peninsular War, created an opportunity for Napoleon to assert control and support the emergence of a more progressive regime aligned with his vision for Europe.
