Helsinki has a long tradition of sports: the city gained much of its initial international recognition during the 1952 Summer Olympics, and the city has arranged sporting events such as the first World Championships in Athletics 1983 and 2005, and the European Championships in Athletics 1971, 1994, and 2012. Helsinki hosts successful local teams in both of the most popular team sports in Finland: football and ice hockey. Helsinki houses HJK Helsinki, Finland's largest and most successful football club, and IFK Helsingfors, their local rivals with 7 championship titles. The fixtures between the two are commonly known as Stadin derby. Helsinki's track and field club Helsingin Kisa-Veikot is also dominant within Finland. Ice hockey is popular among many Helsinki residents, who usually support either of the local clubs IFK Helsingfors (HIFK) or Jokerit. HIFK, with 14 Finnish championships titles, also plays in the highest bandy division, along with Botnia-69. The Olympic stadium hosted the first ever Bandy World Championship in 1957.
