After discovering the value of the plant, from 1833 the wealthier Hispanic Yucatecos had started plantations to cultivate it on a large scale.
Not long after the henequen boom, a boom in sugar production led to more wealth for the upper class.
They had expanded their sugar and henequen plantations by encroaching on Maya communal land, and typically abused their Maya workers by treating them poorly and underpaying them.
Rebel Maya leaders in their correspondence with British Honduras (Belize) will most often cite oppressive taxation as the immediate cause of the war.
