League One is the third tier of professional football in England, sitting below the EFL Championship and above League Two. It features 24 teams that compete for promotion to the higher division. Each season, the top teams earn a chance to move up, while the bottom teams face relegation to League Two. The league operates on a system of promotion and relegation, meaning that performance in each season directly affects a team's standing in the following year. Matches are played on a home-and-away basis, and the season typically runs from August to May, culminating in a series of exciting fixtures and rivalries.
