Bakır devri, or the Copper Age, is a prehistoric period characterized by the use of copper tools and weapons. This era followed the Neolithic period and marked significant advancements in metallurgy. People began to extract copper from ores, leading to the creation of more durable and effective tools compared to those made of stone. During the Bakır devri, societies became more complex, with the development of trade networks and the establishment of permanent settlements. This period also saw the rise of early forms of social organization and the beginnings of urbanization, laying the groundwork for future civilizations.
