João Baptista da Silva Lagos
The Man Who Brought Cacao to Africa
Men and Women of Cacao · History of Cacao
On November 30, 1821, João Baptista da Silva Lagos wrote to the king of Portugal about a shipment with a future still attached to its roots. He had brought boxes of small cacao trees from Bahia, Brazil, to the islands of São Tomé and Príncipe. He had ordered them planted for distribution to farmers. He had inspected the ground himself. [1]
The document captures a turning point in unusually practical terms: a governor, young trees, selected land, and a plan to earn money from future harvests. The man associated with this transfer helped open a major chapter in African cacao cultivation. The surviving letter also moves the story earlier than the familiar date of 1822. [1]
An Atlantic economy looking for another crop
The islands already had a long agricultural history under Portuguese rule. Sugar plantations had flourished there in the sixteenth century, built on enslaved labor. Their fortunes declined as Brazilian sugar expanded. Over time, the island economy turned toward subsistence farming and supplying ships engaged in the slave trade. Coffee, then cacao from Brazil, helped revive plantation agriculture in the nineteenth century. [3]
Silva Lagos belonged to that imperial world. He had previously served as captain-major and governor of the archipelago, and historian Gerhard Seibert associates him with an earlier introduction of coffee from Brazil in 1787. Cacao entered a project of agricultural development shaped by colonial authority and commercial ambition. [2]
The decision inside the letter
Writing to King João VI, Silva Lagos referred to royal instructions dated October 30, 1819. His report described taking the cacao trees from Bahia, arranging their planting, and choosing ground for cacao and expanded coffee cultivation. He also named José Manuel Ferreira, an officer with agricultural experience, whom he instructed to visit the plantings once or twice each month. [1]
That detail brings the project into focus. Transporting seedlings was one step. Keeping a new crop under supervision, encouraging its cultivation, and persuading people to wait for a harvest were part of the undertaking. In his own account, Silva Lagos was organizing an agricultural enterprise.
His letter explained the attraction plainly: these crops could generate profits for inhabitants and revenue for the Crown. He also acknowledged the delay before trees bore fruit. The commercial decision therefore involved patience as well as transport—a commitment to something that would take years to produce its return. [1]
Why the date changed
For generations, histories commonly repeated 1822 as the year cacao arrived on Príncipe. The introduction was often credited to José Ferreira Gomes, a Brazil-born shipowner and official, with a story that the tree was initially grown as an ornamental plant. [2]
Seibert revisited that tradition using the governor’s letter, held in Lisbon’s Arquivo Histórico Ultramarino. A report written in November 1821 and describing trees already brought and planted cannot support 1822 as the beginning of that particular transfer. Seibert concludes that the introduction occurred earlier, possibly in 1820, and that its purpose was commercial from the outset. [2]
The letter gives Silva Lagos a firm place in the record. It does not establish a first landing day, identify every person involved, or prove that no earlier experiment occurred anywhere on the African continent. The subtitle of this profile follows his role in a documented transfer that helped establish cacao on the Gulf of Guinea islands.
What grew after the seedlings
The consequences unfolded over decades. By the end of the nineteenth century cacao had overtaken coffee as the archipelago’s principal export crop. In the early twentieth century, São Tomé and Príncipe briefly became the world’s largest cacao producer. The shipment Silva Lagos reported belonged to the beginning of a transformation he could not have watched in full. [3]
That expansion also carried a grave human cost. The later plantation economy depended on coercive labor arrangements, including forced recruitment and restrictions on workers’ freedom. Research into the twentieth-century plantations records people fleeing abuse and struggling to secure their return home. Commercial success and the experiences of those who worked the land must be read together. [4]
Beyond the islands
Cacao spread through other African settings and through the decisions of African growers. In the Gold Coast, now Ghana, Tetteh Quarshie’s return from Fernando Po with cacao pods in 1879 became an important step in the expansion of cultivation. Farmers obtained planting material from his Mampong farm and established their own trees. That story belongs to another profile in this series. [5]
Silva Lagos’s letter preserves an earlier link in the chain: American trees deliberately moved into an African colonial economy. His report ends our search for a vague founding legend with something tangible to examine. There were boxes of living trees, people assigned to tend them, and land set aside for a crop whose future was still underground.
