The ancient kingdom credited with developing the first known writing system is Sumer, located in present-day Southern Iraq. The Sumerians created cuneiform writing around 3200 BCE, using wedge-shaped marks on clay tablets. This innovative system facilitated record-keeping, communication, and the transmission of knowledge, playing a critical role in the administration of city-states. Sumerian ingenuity in writing paved the way for the preservation of history, literature, and legal codes. Following Sumer, other civilizations adopted and adapted written forms, highlighting the importance of writing in human development and cultural expression.
