In archaeology, the Iron Age is the prehistoric period in any area during which cutting tools and weapons were mainly made of iron or steel. The adoption of this material coincided with other changes in society, including differing agricultural practices, religious beliefs and artistic styles.

The Iron Age is the last principal period in the three-age system for classifying prehistoric societies, preceded by the Bronze Age and the Stone Age. Its dates and context vary depending on the geographical region. The Iron Age in each area ends with the beginning of the historical period, i.e. the local production of ample written sources. Thus, for instance, the British Iron Age ends with the Roman Conquest.

The term "Iron Age" was originally derived from the "Ages of Man", i.e. the ages of human existence on the Earth according to Classical mythology. While the earlier ages in this scheme are entirely mythical ("The Golden Age" and the "Silver Age"), the later Bronze Age and Iron Age of classical mythology preserve the memory of actual periods when the metals mentioned dominated human life.[citation needed]

Classically, the Iron Age is taken to begin in the 12th century BC in the ancient Near East, ancient India (with the post-Rigvedic Vedic civilization), ancient Iran, and ancient Greece (with the Greek Dark Ages). In other regions of Europe, it started much later. The Iron Age began in the 8th century BC in Central Europe and the 6th century BC in Northern Europe. Iron use, in smelting and forging for tools, appears in West Africa by 1200 BC, making it one of the first places for the birth of the Iron Age.[1][2][3] (It is believed that meteoric iron, or iron-nickel alloy, was used by various ancient peoples thousands of years before the Iron Age.[4][5] This iron, being in its native metallic state, required no smelting of ores.)

The Iron Age is divided into two subsections, Iron I and Iron II. Iron I (1200–1000 BC) illustrates both continuity and discontinuity with the previous Late Bronze Age. There is no definitive cultural break between the thirteenth and twelfth century throughout the entire region, although certain new features in the hill country, Transjordan and coastal region may suggest the appearance of the Aramaean and Sea People groups. There is evidence, however, that shows strong continuity with Bronze Age culture, although as one moves later into Iron I the culture begins to diverge more significantly from that of the late second millennium.

The Iron Age is usually said to end in the Mediterranean with the onset of historical tradition during Hellenism and the Roman Empire, in India with the onset of Buddhism and Jainism, in China with the onset of Confucianism, and in Northern Europe with the early Middle Ages.

The arrival of iron use in various areas is discussed in more detail below, broadly in chronological order.

Iron use in the Bronze Age

By the Middle Bronze Age, increasing numbers of smelted iron objects (distinguishable from meteoric iron by the lack of nickel in the product) appeared throughout Anatolia, Mesopotamia, the Indian subcontinent, the Levant, the Mediterranean, and Egypt. Some sources suggest[who?] that iron was being created in some places then as a byproduct of copper refining, as sponge iron, and was not reproducible by the metallurgy of the time.[citation needed]

The earliest systematic production and use of iron implements originates in Anatolia. African production of iron has been suggested to have begun at around the same time, and possibly even before Anatolia, but recent discoveries suggest that iron working appeared in Anatolia since 2000 BC[6]. Recent archaeological research at Ganges Valley, India showed early iron working by 1800 BC.[7] By 1200 BC, iron was widely used in the Middle East but did not supplant the dominant use of bronze for some time.

Transition from bronze to iron

Bronze was previously used to make tools because its melting point is lower than that of iron. The Iron Age began with the development of higher temperature smelting techniques. During the Iron Age, the best tools and weapons were made from steel, an alloy consisting of iron with a carbon content between 0.02% and 1.7% by weight. Steel weapons and tools were nearly the same weight as those of bronze, but stronger. However, steel was difficult to produce with the methods available. Therefore, many Iron Age tools were fashioned of wrought iron.[8] Wrought iron is weaker than bronze, but because it was less expensive, and more easily sharpened, people used it anyway. Iron is by itself an adequately strong metal without additional alloys (although it could be further strengthened by case-hardening or forge welding small amounts of steel to areas subject to wear such as edges). Bronze, on the other hand, requires copper and tin, which are less common than iron. Additionally, iron can be sharpened by grinding whereas bronze must be reforged.[citation needed]

Around 1800 BC, for reasons yet unknown to archaeologists, tin became scarce in the Levant, causing a decline in bronze production. Copper, also, came to be in short supply. As a result, pirate groups around the Mediterranean, from around 1800–1700 BC onward, began to attack fortified cities in search of bronze, to remelt into weaponry.

Bronze was much more abundant in the period before the 12th to 10th century, and Snodgrass[9][10] suggests that a shortage of tin, as a result of the trade disruptions in the Mediterranean at this time, forced peoples to seek an alternative to bronze. That many bronze items were recycled and made from implements into weapons during this time, is evidence of this.

Ancient Near East

Transition

The Iron Age in the Ancient Near East is believed to have begun with the discovery of iron smelting and smithing techniques in Anatolia or the Caucasus and Balkans in the late 2nd millennium BC (circa 1300 BC).[11]

The use of iron weapons instead of bronze weapons spread rapidly throughout the Near East or the southwest Asia by the beginning of the 1st millennium BC. Anatolians had begun forging weapons out of iron, which was a superior metal to bronze, by 1500 BC at the latest.

The use of iron weapons by the Hittites was believed to have been a major factor in the rapid rise of the Hittite Empire.[citation needed] Because the area in which iron technology first developed was near the Aegean, the technology expanded into both Asia and Europe simultaneously,[12][13] aided by Hittite expansion. The Sea Peoples and the related Philistines are often associated with the introduction of iron technology into Asia, as are the Dorians with respect to Greece.[14]
