The Spanish colonization of the Philippines had three main aims: spreading Catholicism, acquiring wealth through gold and trade, and increasing Spain's glory by building its empire. To govern its colonies, Spain established the Laws of the Indies, which imposed taxes on indigenous peoples and established systems of forced labor. The Spanish built churches, established religious orders, and introduced education to convert Filipinos to Christianity. They developed a political system headed by a Governor-General and including local governors. Overall, the Spanish colonial system aimed to assert control over the Philippines through religious, economic and political domination of indigenous peoples.
