Football is one of the most popular sports in the city. The two teams with the largest following are thirteen-time Polish champion Wisła Kraków, and five-time champion Cracovia, both founded in 1906 as the oldest still existing in Poland. They have been involved in the most intense rivalry in the country and one of the most intense in all of Europe, known as the Holy War (""). Other football clubs include Hutnik Kraków, Wawel Kraków, and one-time Polish champion Garbarnia Kraków. There is also the first-league rugby club Juvenia Kraków. Kraków has a number of additional, equally valued sports teams including twelve-time Polish ice hockey champions Cracovia and the twenty-time women's basketball champions Wisła Kraków.
