The European Cup Winners' Cup was a prestigious football tournament held annually from 1960 to 1999. It was organized by the Union of European Football Associations (UEFA) and featured domestic cup winners from various European countries. The competition was known for showcasing clubs that had won their national cup competitions, providing them a platform to compete at a continental level. The tournament was discontinued in 1999, with its last edition won by Chelsea FC. Following its closure, the UEFA decided to merge the Cup Winners' Cup with the UEFA Champions League, allowing for a more streamlined competition structure in European football.
