This spur, worn over a riding boot, was made in Mexico in the mid-1800s. Rubbed against the animal's side, spurs are one of the instruments that riders use to direct horses. The spikes on this spur are set on a small wheel called a rowel, making this a rowel spur. Horses and good riding equipment, such as spurs, saddles, stirrups, and leather coverings, played a fundamental role in the European conquest, exploration, and settlement of wide areas of North America.
