TheCopa del Rey de Baloncesto (English:BasketballKing's Cup) is an annual cup competition forSpanishbasketball teams organized by Spain's top professional league, theLiga ACB.
Originally known as theCopa de España de Baloncesto, was first played in 1933 and contested in its first editions only by teams from the provinces ofMadrid andBarcelona. It was the first nationwide basketball competition played inSpain. During theFrancoism, it was referred as theCopa del Generalísimo de Baloncesto, before becoming theCopa del Rey de Baloncesto in 1977.
Until the establishment of theACB in 1983, the Cup was played in its latest rounds with double-legged series and its final as a single game in a neutral venue. In several seasons, there was a group stage as first round.
From 1983 and 1986, a Final Four format was adopted. The two best qualified teams from the two groups of theLiga ACB at the end of the first stage qualified for the tournament.
Since 1987, the tournament was expanded toFinal Eight format has been used. Since the league is played with a round-robin single group, the top seven teams at the end of the first half of the regular season from theSpanish League and the host one, if it is not between these teams, qualify for the tournament. The eight teams play a knockout tournament at one venue, over four days, eventually producing a winner.
TheCopa del Rey is one of the highlights of the Spanish sporting calendar.
