Royal hunting, also royal art of hunting, was a hunting practice of the aristocracy throughout the known world in the Middle Ages, from Europe to Far East. While humans hunted wild animals since time immemorial, and all classes engaged in hunting as an important source of food and at times the principal source of nutrition, the necessity of hunting was transformed into a stylized pastime of the aristocracy. More than a pastime,l interaction, essential training for war, and a privilege and measurement of nobility. In Europe in the High Middle Ages the practice was widespread.

A limer, or lymer, was a kind of dog, a scenthound, used on a leash in medieval times to find large game before it was hunted down by the pack. It was sometimes known as a lyam hound/dog or lime-hound, from the Middle English word lyam, meaning 'leash'. The French cognate limier has sometimes been used for the dogs in English as well. The type is not to be confused with the bandog, which was also a dog controlled by a leash, typically a chain, but was a watchdog or guard dog.
