How Many Countries Did Spain Conquer?

Spain didn't "conquer countries" in the modern sense but built a global empire (15th–20th centuries) across:

• Americas: Most of South/Central America, Mexico, Caribbean, SW USA (Viceroyalties of New Spain, Peru, New Granada, Río de la Plata)
• Asia-Pacific: Philippines, Guam, Mariana Islands, Caroline Islands, briefly Taiwan, parts of Indonesia
• Africa: Ceuta, Melilla, Canary Islands, Western Sahara, Equatorial Guinea, Morocco (protectorate)
• Europe: Netherlands, Belgium, parts of Italy, Portugal (1580–1640)

At its peak (1580s), the Spanish Empire spanned ~13 million km². Decolonization completed 1975 (Western Sahara). Today, Spain retains Ceuta, Melilla, Canaries.
