21. Amazonas
Capital: Manaus
Nestled in the northern expanse of Brazil, Amazonas shares its borders with Peru, Colombia, and Venezuela. As the largest state in Brazil and the third-largest in the Americas, it is a land dominated by the majestic Amazon Plain. Rising above this lush terrain is Pico da Neblina, Brazil’s highest peak at 2,994 meters.

The climate here is quintessentially tropical rainforest—hot, humid, and drenched in rain throughout the year. Historically, Amazonas began as a Portuguese colony before becoming an official state of the Brazilian Empire. Today, Portuguese remains the primary language, enriched over time with words borrowed from indigenous tongues.
