The Portuguese were motivated to explore and conquer Brazil primarily due to the region's vast natural resources, particularly sugarcane, which was highly sought after in Europe. The lucrative sugar trade spurred the establishment of large plantations, leading to a thriving export economy centered on sugar products. This agricultural focus necessitated a cheap and abundant labor force, prompting the Portuguese to engage in the Transatlantic Slave Trade to import enslaved Africans, who were forced to work in the harsh conditions of plantations and mines.
The initial indigenous population suffered greatly due to enslavement, diseases brought by Europeans, and the violent upheaval of their societies. The Portuguese sought to ensure a steady labor supply, which led to the systematic importation of African slaves. This contributed significantly to the economic growth of Brazil during the colonial period.
By the early 19th century, Brazil sought independence from Portuguese rule, officially declaring independence in 1822. Although the slave trade officially ended in 1850, the institution of slavery persisted until 1888, when Brazil became the last country in the Americas to abolish it. Overall, economic motivations such as resource exploitation, agricultural expansion, and the demand for labor played central roles in the Portuguese exploration and subsequent colonization of Brazil.
