Promotion and Relegation is a system used in many sports leagues, particularly in soccer, to determine which teams move up or down between different levels of competition. At the end of a season, the best-performing teams in a lower division are promoted to a higher division, while the lowest-performing teams in the higher division are relegated to the lower division. This system encourages competition and rewards success. This method is common in leagues around the world, such as the English Premier League and La Liga. It creates a dynamic environment where teams must consistently perform well to avoid dropping to a lower tier, making each match significant for both players and fans.
