The introduction of iron after 1000 BC brought new tools and weapons to Europe. Smelting technology and higher furnace temperatures were likely the key to iron production, which is generally thought to have originated in Anatolia around 1400 BC among the Hittites, but there are a few earlier examples of iron artifacts as old as 2300 BC in Turkey. Iron produced sharper, more readily available implements and was in great demand. In contrast to copper and tin, whose sources were limited, iron was found in a variety of forms in many places across the continent. Veins of iron ore were exploited in Iberia, Britain, the Alps, the Carpathian Mountains, and elsewhere. Bog iron was exploited in northern Europe. Carbonate sources of iron in other areas enabled local groups to obtain the raw materials necessary for producing this important material. At the same time, the collapse of the dominant Bronze Age civilizations of the Aegean changed the flow of raw materials and finished products across Europe. Greece fell into a Dark Age following the demise of the Mycenaean city-states. The Etruscans were on the rise in Italy. Rome was a small town at the border of the Etruscan region. Soon, however, new centers of power in classic Greece and Rome emerged, bringing writing and, with it, history to Europe. Again, we can observe important and dramatic differences between the “classic” areas of the Mediterranean and the northern parts of “barbarian” Europe. The chronology for the Iron Age in much of Europe is portrayed in Figure 6.2. The Iron Age begins earlier in the Mediterranean area, ca. 900 BC, where the Classical civilizations of Greece, the Etruscans, and eventually Rome emerge in the first millennium BC. Rome and its empire expanded rapidly, conquering much of western Europe in a few decades before the beginning of the Common Era and Britain around ad 43, effectively ending the prehistoric Iron Age in these parts of the continent. The Iron Age begins somewhat later in Scandinavia, around 500 BC.
