7 the Roman Empire
Eli J. S. Weaverdyck 7 The Roman Empire I Introduction The Roman Empire was one of the largest and longest lasting of all the empires in the ancient world.1 At its height, it controlled the entire coast of the Mediterranean and vast continental hinterlands, including most of western Europe and Great Brit- ain, the Balkans, all of Asia Minor, the Near East as far as the Euphrates (and be- yond, briefly), and northern Africa as far south as the Sahara. The Mediterranean, known to the Romans as mare nostrum(‘our sea’), formed the core. The Mediterranean basin is characterized by extreme variability across both space and time. Geologically, the area is a large subduction zone between the African and European tectonic plates. This not only produces volcanic and seismic activity, it also means that the most commonly encountered bedrock is uplifted limestone, which is easily eroded by water. Much of the coastline is mountainous with deep river valleys. This rugged topography means that even broadly similar climatic conditions can pro- duce drastically dissimilar microclimates within very short distances. In addition, strong interannual variability in precipitation means that local food shortages were an endemic feature of Mediterranean agriculture. In combination, this temporal and spatial variability meant that risk-buffering mechanisms including diversification, storage, and distribution of goods played an important role in ancient Mediterranean survival strategies. Connectivity has always characterized the Mediterranean.2 While geography encouraged mobility, the empire accelerated that tendency, inducing the transfer of people, goods, and ideas on a scale never seen before.3 This mobility, combined with increased demand and the efforts of the imperial govern- ment to mobilize specific products, led to the rise of broad regional specializations, particularly in staple foods and precious metals.4 The results of this increased con- It has also been the subject of more scholarship than any other empire treated in this volume.
