In the 1930s when the importance of the horse began to decline, it was thought that "First Monday" would vanish. There appeared about a ten-year void in Texas between the horse-raising era and the tractor era, and out of state horse traders began to bring in horses to supply this void. Horse buyers from all over the state began to attend "First Monday" and the crowds got larger and larger. It became known statewide as the place to buy a good "bronc".
