Juan de Serras was a prominent Jamaican Maroon leader in the seventeenth century, known for his unwavering resistance against British colonization. His community, primarily based around Los Vermajales in Jamaica, was referred to as the Karmahaly or Varmahaly Maroons by the English. De Serras emerged as a key figure in the aftermath of the English conquest of Jamaica by the Spanish.
Unlike some other Maroon leaders, such as Juan de Bolas (also known as Juan Lubolo) who eventually allied with the English, de Serras remained steadfastly loyal to the Spanish cause. He led his followers in establishing palenques, or stockaded mountain farms, in the western end of Cockpit Country. From these strategic locations, de Serras and his Maroon warriors conducted numerous raids on English settlements, burning plantations and houses, killing English soldiers and settlers, and even attacking the capital, Spanish Town.
De Serras’s community served as a refuge for slaves escaping from English owners, which bolstered their numbers and strengthened their resistance. His unwillingness to compromise with the British colonial authorities was evident when he rejected peace overtures, unlike Juan de Bolas who had switched allegiance to the English. This steadfast opposition led to increased tension with the British, culminating in Governor Thomas Modyford declaring war on the Karmahaly Maroons.

Despite attempts at negotiation, including a brief lull in fighting when de Serras sent one of his warriors, Domingo, to discuss peace, the Maroon leader used this opportunity to relocate his people to a more secure environment, possibly in the Blue Mountains. From this new base, de Serras and his followers resumed their attacks on English colonial authorities.
The last recorded campaign against de Serras was led by Henry Morgan, the former buccaneer and lieutenant-governor of Jamaica. Although Morgan was unable to defeat de Serras and his Maroons, reports about them ceased after this encounter. It is theorized that de Serras and his followers may have retreated further into the Blue Mountains, becoming less accessible to the English colonial authorities and possibly merging with other Maroon groups. Juan de Serras’s legacy as a Maroon leader is marked by his unyielding resistance to British colonization and his role in establishing and maintaining independent Maroon communities in Jamaica. His actions contributed significantly to the long-standing tradition of Maroon resistance on the island, which would continue well into the subsequent century.
