Maryannu is an ancient word for the caste of chariot-mounted hereditary warrior nobility which dominated many of the societies of the Middle East during the Bronze Age. The term is attested in the Amarna letters written by Haapi. Robert Drews writes that the name 'maryannu' although plural takes the singular 'marya', which in Sanskrit means young warrior, and attaches a Hurrian suffix.(Drews:p. 59) He suggests that at the beginning of the Late Bronze Age most would have spoken either Hurrian or Aryan but by the end of the 14th century most of the Levant maryannu had Semitic names.
