The Pre-Columbian Maya were organized into a series of independent kingdoms or polities rather than unified into a single state. The vast majority of studies of Maya states focus on the apogee of their development in the classic period, ca. 250-850 C.E. As a result, Maya states are defined according to the specific political structures that characterized classic period lowland Maya society. The Origins of Maya States is the first study in over 30 years to examine the origins and development of these states specifically during the preceding preclassic period, ca. 1000 B.C.E. to 250 C.E.
