The Early Bronze Age, spanning approximately 3300 to 2100 BCE, marks a significant period in human history characterized by the emergence of metallurgy, particularly the use of bronze. This era saw the rise of complex societies and trade networks, leading to advancements in agriculture, architecture, and art. During this time, notable civilizations such as the Sumerians in Mesopotamia and the Indus Valley Civilization flourished. The development of writing systems, like cuneiform, and the construction of monumental structures reflect the increasing sophistication of these societies, laying the groundwork for future cultural and technological advancements.
