Cuneiform is considered the single most significant legacy of the ancient Sumerians of Mesopotamia. It was developed c. 3500-3000 BCE, is considered the first written language created, and was used for well over 1000 years. The oldest-dated cuneiform tablets mostly contain records of business transactions. However, over the centuries, cuneiform tables covered various different topics such as affairs of state, religion, magic, history, contracts, and were used for personal and professional communication (letters).
