Cultural, Demographic and Environmental Dynamics of the Copper and Early Bronze Age in Iberia (3300–1500 BC): Towards an Interregional Multiproxy Comparison at the Time of the 4.2 ky BP Event

Abstract

This paper presents the first comprehensive pan-Iberian overview of one of the major episodes of cultural change in later prehistoric Iberia, the Copper to Bronze Age transition (c. 2400–1900 BC), and assesses its relationship to the 4.2 ky BP climatic event. It synthesizes available cultural, demographic and palaeoenvironmental evidence by region between 3300 and 1500 BC. Important variation can be discerned through this comparison. The demographic signatures of some regions, such as the Meseta and the southwest, diminished in the Early Bronze Age, while other regions, such as the southeast, display clear growth in human activities; the Atlantic areas in northern Iberia barely experienced any changes. This paper opens the door to climatic fluctuations and inter-regional demic movements within the Peninsula as plausible contributing drivers of particular historical dynamics.
