final technological and cultural stage in the Stone–Bronze–Iron-Age sequence. The date of the full Iron Age, in which this metal for the most part replaced bronze in implements and weapons (weapon), varied geographically, beginning in the Middle East and southeastern Europe about 1200 BCE but in China not until about 600 BCE. Although in the Middle East iron had limited use as a scarce and precious metal as early as 3000 BCE, there is no indication that people at that time recognized its superior qualities over those of bronze. Between 1200 and 1000, however, the export of knowledge of iron metallurgy and of iron objects was rapid and widespread. With the large-scale production of iron implements came new patterns of more permanent settlement. On the other hand, utilization of iron for weapons put arms in the hands of the masses for the first time and set off a series of large-scale movements of peoples that did not end for 2,000 years and that changed the face of Europe and Asia.
