A knight was a highly skilled and noble soldier in medieval Europe who served a lord or king. They were often mounted warriors who wore armor and fought on horseback. Knights were trained from a young age in the art of combat and chivalry, and were expected to uphold a code of honor and loyalty. They played a crucial role in battles and warfare, as well as in tournaments and jousting competitions. Knights were respected members of society and were often rewarded with land, titles, and other privileges for their service.
