The Iron Age is a significant period in human history characterized by the widespread use of iron for tools and weapons. It followed the Bronze Age and marked a major technological advancement that allowed societies to develop more complex structures and engage in warfare more effectively. This era saw the rise of various civilizations, including the Celtic tribes in Europe and the Hittites in Anatolia. During the Iron Age, societies became more organized, leading to the establishment of trade networks and urban centers. The use of iron not only improved agricultural practices but also facilitated the growth of empires, such as the Roman Empire, which would later dominate much of Europe and the Mediterranean region.
