Los Millares participated in the continental trends of Megalithism and the Beaker culture. Analysis of occupation material and grave goods from the Los Millares cemetery of 70 "tholos" tombs with port-hole slabs has led archaeologists to suggest that the people who lived at Los Millares were part of a stratified, unequal society which was often at war with its neighbours. The Los Millares civilisation was replaced circa 1800 BC, with the arrival of Bronze by the El Argar civilisation, whose successor culture is embodied in the contemporary culture of Vila Nova de São Pedro in nearby Portugal.
