 On June 8, 1518, Juan de Grijalva landed in the province of Potonchán and met Tabscoob to whom, it is said, Grijalva gave his green velvet doublet.Between Potonchán and the island of Tris was a Nahuatl town called Xicalango, which was a major port on the Gulf of Mexico, but being different from the Maya race, had constant friction with Potonchán since the Xicalangos frequently crossed territory within the province of Tabasco.This led to a war in the year 1513 in which Tabscoob led an army of 20,000 men and defeated the Xicalangos.
