The ancient civilization known for its system of writing called cuneiform is Mesopotamia, specifically the Sumerians. Cuneiform, one of the earliest known forms of writing, emerged around 3200 BCE in what is now southern Iraq. It was primarily inscribed on clay tablets using a stylus, allowing civilizations to keep records, document transactions, and preserve literature. This writing system was fundamental in the development of language, administration, and culture in Mesopotamia. Cuneiform records have provided invaluable insight into ancient Sumerian life, law, and religion, influencing subsequent writing systems and cultures throughout history.
