Horse
Horse meat forms a significant part of the culinary traditions of many countries, particularly in Eurasia. The eight countries that consume the most horse meat consume about 4.3 million horses a year. For the majority of humanity's early existence, wild horses were hunted as a source of protein. During the Paleolithic, wild horses formed an important source of food for humans. In many parts of Europe, the consumption of horse meat continued throughout the Middle Ages until modern times, despite a ban on horse meat by Pope Gregory III in 732. Horse meat was also eaten as part of Germanic pagan religious ceremonies in Northern Europe.
