What is "kejache"

The Kejache (sometimes spelt Kehache, Quejache, Kehach, Kejach or Cehache) were a Maya people in the southern Yucatán Peninsula at the time of Spanish contact in the 17th century. The Kejache territory was located in the Petén Basin in a region that takes in parts of both Guatemala and Mexico. Linguistic evidence indicates that the Kejache shared a common origin with the neighbouring Itzas to their southeast and the Kejache may have occupied the general region since the Classic period (c. AD 250–900). The Kejache were initially contacted by conquistador Hernán Cortés in 1525, they were later in prolonged contact with the Spanish as the latter opened a route southwards towards Lake Petén Itzá.
