With the decline of Wari and Tiwanaku, political power and cultural initiatives shift from the highlands to the coastal desert. The north coast of Peru, which has abundant water supply for irrigation, is the center of development and sees the rise of the powerful Chimú state. Small and mid-sized kingdoms control the valleys of the central and southern coasts. In the highlands, many groups, large and small, do not attain the same political complexity. No territorial expansion occurs, nor is monumental architecture built. Despite political fragmentation, many groups have similar societal goals and approaches to art. There is increased emphasis on secularism and accumulation of wealth. In the arts, a trend toward standardization and repetitiveness dominates; subject matter is limited. Coastal peoples focus on sea-related motifs, geometric designs, and a stylized frontal human figure.
