Local Conflict...

The borders of Barbados are fixed and as such the colony went through no changes in size. However, the island was not immune to the growing pains that plagued other British colonies of the time. The introduction of sugar technology early on in its settlement created the climate needed for extreme social and economic upheaval.

Before Jamaica had its leap forward in the industry, Barbados was the most lucrative of the British colonies in terms of sugar production. This new found affluence led to a major shift in numbers and types of workers. Specifically, the Irish indentured servants that had come to the island early and in large numbers began to be replaced by cheap slave labor from Africa. This had the effect of diminishing the white population while increasing the black population on Barbados. This shift also brought the fear of slave revolts.

Armed Rebellion?

Though the black population was increasing and there had been "agitation" among slaves against their masters arriving along with Methodist proselytizers, there are no reports of any major slave revolt taking place between 1702 and 1815. The paranoia of a successful revolt led to the creation of large and powerful militia forces tasked with preserving the sovereignty of the wealthy planters on Barbados. This militia, coupled with a decline in importation of slaves and the rise of an indigenous creole culture on the island assured that the planters on Barbados remained relatively safe from harm.
