Explain why the ancient civilizations of Mesopotamia invented cuneiform writing on clay tablets?

Administrative needs related to economic management

The ancient Mesopotamians invented cuneiform writing primarily because they needed to keep track of their accounts. Their society was becoming complex: trade, taxes, agriculture, livestock... There was a lot to memorize and manage orally, so a precise note-taking system was very useful. Writing allowed them to clearly record herds, grain stocks, commercial exchanges, and tax revenues. The earliest texts found were often simple lists or inventories, commercial receipts, or tax records. It was primarily this practical and administrative necessity that drove the creation of the very first writing system.

Ease and availability of clay as a writing medium

Clay was an ideal material: abundant near the rivers of the Tigris and Euphrates, free, and easy to use without complicated tools. It was enough to shape the tablet with a little water, then to inscribe the signs with a pointed reed called a calamus. Once dried in the sun or sometimes fired in a kiln, the tablet became extremely durable and could last for centuries (even millennia for some). There was no need to import complicated or expensive materials like Egyptian papyrus: clay was already there, everywhere, ready to use. This practicality allowed Mesopotamian scribes to write tons of administrative, economic, religious, and even literary texts, greatly facilitating its widespread use.

Importance of writing for cultural and social development

Thanks to cuneiform writing, the ancient Mesopotamians were able to preserve and transmit their knowledge, mythological tales, and history. Without writing, it would have been impossible to have a reliable collective memory: stories and rules often changed when passed orally from one generation to another. With the emergence of writings engraved on clay, literary works like the Epic of Gilgamesh could be preserved over several centuries. Laws (Code of Hammurabi, for example) could also be established, allowing societies to organize themselves more effectively and sustainably. These tablets also served to educate new generations, thus contributing to the formation of a strong and common cultural identity, essential for the civilization to thrive.

Role of cuneiform writing in the expansion of trade and agriculture

The Mesopotamians quickly realized that clearly recording their transactions greatly simplified life. Thanks to cuneiform writing, they kept accurate records of trade exchanges: this avoided disputes and misunderstandings when bartering goods. Whether it was to exchange grains, livestock, or handcrafted products, writing provided solid evidence of agreements made. The same was true for agriculture: scribes precisely recorded the volume of harvests, the organization of grain reserves, and the management of cultivated lands. As a result, agriculture and commerce thrived because they were better organized, with fewer errors and losses. Cuneiform writing served as a kind of external memory for the entire economy!

Comparison with other contemporary writing systems

At the time when the Sumerians invented cuneiform, the Egyptians were developing hieroglyphs, a system that combined images and symbols to represent sounds and objects. Unlike cuneiform, which was quickly engraved in wet clay, hieroglyphs were often inscribed on papyrus or stone surfaces, requiring more time and precision. Meanwhile, in the Indus Valley, there was a different script, still undeciphered today, composed of short and simple symbols, somewhat like stylized pictograms. The Mesopotamians mainly used their writing for record-keeping and organizing trade, while the Egyptians used it more to celebrate royal exploits, myths, and sacred rituals. It is these differences in usage and available materials that produced writing styles that are both varied and interesting.
