Beginning in the Middle Ages, a squire was the shield- or armour-bearer of a knight. At times, squires acted as a knight’s errand runner or servant. Use of the term evolved over time. Initially, squires were a knight’s trainees/apprentices. Later, a village leader or a lord of the manor might be called a squire, and still later, the term applied to key public figures, such as justices of the peace or members of parliament. In contemporary American usage, squire is the title given to justices of the peace or similar local dignitaries.
