A squire was a young man training to become a knight in medieval Europe. Usually starting around age 14, a squire served an experienced knight, learning combat skills, horsemanship, and the code of chivalry. He took care of his knight's armor and weapons, helped him dress for battle, and accompanied him to tournaments and wars. Think of it as a rigorous apprenticeship: the squire practiced swordplay, learned to ride in heavy armor, and studied the responsibilities of knighthood. After years of faithful service and training, a squire who proved himself worthy would be knighted in a special ceremony, finally earning the title and status he'd worked toward.

The word also became a title in England for country gentlemen who owned land but weren't nobles. These squires were often the most important people in their villages, settling disputes and organizing local affairs.

In stories like The Adventures of Robin Hood or tales of King Arthur, squires appear as loyal companions to knights, sometimes young and eager, sometimes getting into amusing mishaps as they learn their duties. The relationship between knight and squire was built on trust and respect: the knight taught and protected his squire, while the squire served faithfully and learned everything he could about becoming a warrior and leader.
