Brazil
The majority of Brazilians are of mixed European, Indigenous, and African ancestry. The Portuguese were the first Europeans to arrive in Brazil in 1500, and they brought enslaved Africans to work on sugar plantations. However, the majority of African slaves were brought to Brazil in the 18th and 19th centuries. Today, Brazil has the largest population of people of African descent outside of Africa.
Mexico
The majority of Mexicans are of mixed European and Indigenous ancestry. The Spanish arrived in Mexico in the 1500s, and they brought enslaved Africans to work in the mines and on plantations. However, the majority of African slaves were brought to Mexico in the 17th and 18th centuries. Today, Mexico has a significant population of people of African descent, but they make up a smaller percentage of the population than in Brazil.
Yucatán
The Yucatán is a region of Mexico that is home to a large population of Maya people. The Maya are an indigenous people who have lived in the Yucatán for centuries. The Spanish arrived in the Yucatán in the 1500s, and they brought enslaved Africans to work on haciendas (large plantations). However, the majority of African slaves were brought to the Yucatán in the 17th and 18th centuries. Today, the Yucatán has a significant population of people of African descent, but they make up a smaller percentage of the population than in Brazil or Mexico.
In summary, while there is a significant African diaspora in Brazil, Mexico, and the Yucatán, the majority of Hispanics and Latinos in these regions are descended from European settlers and indigenous peoples.
