Prehistoric humans invented the knife, while the modern personal eating fork was probably created in the Byzantine Empire. Many previous cultures had used forks to cook and serve food, but the Byzantines used them to eat food as early as the 4th century A.D.
In the Middle Ages, the primary eating utensil in Europe was the knife. People brought their own personal knives to the table, using the tool to cut food, spear it and bring it to their mouths. However, beginning in the 15th century, the Italians began to adopt the fork, and its use spread to Spain. Catherine de Medici, an Italian noblewoman who became queen of France, brought the utensil to her new country in the 1530s. By the 18th century, its use was common throughout Europe.Learn More
