World Junior Championship

The IIHF Ice Hockey World Junior Championships (WJC), commonly known simply as the World Juniors, is an annual event organized by the International Ice Hockey Federation (IIHF) for national under-20 ice hockey teams from around the world. It is traditionally held in late December, ending in the beginning of January.

The main tournament features the top ten ranked hockey nations in the world, comprising the 'Top Division', from which a world champion is crowned. There are also three lower pools—Divisions I, II and III—that each play separate tournaments playing for the right to be promoted to a higher pool, or face relegation to a lower pool.

The competition's profile is particularly high in Canada; its stature has been credited to Canada's strong performance in the tournament (it has won the gold medal sixteen times since its inception), the role of hockey in Canadian culture, along with strong media coverage and fan attendance. As such, in recent years, nearly half of the tournaments have been held in Canadian cities, with the remainder being held in Europe and the United States.

The United States are the defending champion of the tournament, after having beaten Canada to win the 2017 edition.

History
The tournament was first held in 1977 (1974–1976 were not official tournaments). The tournament has been dominated by the teams from Russia/Soviet Union and Canada, together accounting for 29 of the 41 overall gold medals awarded (through 2017). The USSR won the first four official tournaments, while the Canadians put together five straight championships between 1993 and 1997, and another five straight from 2005 to 2009. Canada leads the all-time gold medal count with 16, while USSR/Russia leads the all-time overall medal count with 32. Head-to-head matches between these two countries are always much anticipated.

In addition to the domination of gold medals by these two countries, Canada and Russia (and its predecessor) are joined by the Czech Republic (and its predecessor Czechoslovakia), Finland, Sweden, and the United States in dominating the medals overall. Among them, these six nations have taken every medal in the history of the tournament with the exception of two bronze medals for Slovakia and one bronze medal for Switzerland.

When it began, the World Junior Championship was a relatively obscure tournament. It has since grown in prestige, particularly in Canada, where the tournament ranks as one of the most important events on the sports calendar and during the holiday season. Globe and Mail writer Bruce Dowbiggin credits TSN, along with Canada's strong performance at the tournament, for turning it from an obscure non-event when it acquired the rights in 1991 (which, however, also began growing in prominence due to the Punch-up in Piestany) to one of Canada's most beloved annual sports events, and at the same time cementing the link between Canadian nationalism and hockey, and inspiring the NHL's Winter Classic Based on increasing attendances for countries repeatedly hosting the event, the popularity of the tournament seems to be growing in other nations as well.

At editions of the tournament held in the country, Team Canada matches have consistently sold out, offering large profit guarantees to Hockey Canada and the IIHF. Canada is expected to host the tournament every second year starting in 2015 due to the significantly greater following the tournament has in Canada compared to other participating countries. Originally, Switzerland was selected to host the WJHC in 2010, but withdrew. Buffalo, New York, USA hosted the tournament in 2011 and will host it again in 2018; in both cases, proximity to Canada's population core in Southern Ontario was a key factor in the city winning the bidding rights.

The tournament offers one of the most prestigious stages for young hockey players, able to significantly boost a player's value for upcoming NHL Entry Drafts.

Punch-up in Piestany
One of the most infamous incidents in WJC history occurred in 1987 in Piestany, Czechoslovakia (today's Slovakia), where a bench-clearing brawl occurred between Canada and the Soviet Union. It began when the Soviet Union's Pavel Kostichkin took a two-handed slash at Canadian player Theoren Fleury. The Soviet Union's Evgeny Davydov then came off the bench, eventually leading to both benches emptying. The officials, unable to break up the fight, left the ice and eventually tried shutting off the arena lights, but the brawl lasted for 20 minutes before the IIHF declared the game null and void. A 35-minute emergency meeting was held, resulting in the delegates voting 7–1 (the sole dissenter was Canadian Dennis McDonald) to eject both teams from the tournament. The Canadian team chose to leave rather than stay for the end-of-tournament dinner, from which the Soviet team was banned.

While the Soviets were out of medal contention, Canada was playing for the gold medal, and were leading 4–2 at the time of the brawl. The gold medal ultimately went to Finland, hosts Czechoslovakia took the silver and Sweden, who had previously been eliminated from medal contention, was awarded the bronze.

Participating countries
Sweden, Finland and Canada have participated in all 40 IIHF World Junior Hockey Championships as well as the three unofficial World Junior Hockey Championships. USSR/CIS/Russia and Czechoslovakia/Czech Republic have also participated in all IIHF World Junior Hockey Championships, and the United States have participated in all except one (1976). When Czechoslovakia peacefully split in 1993, the Czech Republic remained in Pool A but Slovakia (Slovak Republic) was placed in Pool C (now Division II). Slovakia was promoted to the top division for the 1996 Championships and have remained there since.

Starting with the 1996 tournament, competition was increased from an 8-round robin to the current 10 team format. Since then Switzerland has become a main participant.

Germany has been a frequent participant in the top pool, having played there roughly half the time in the past decade. Latvia, Belarus, and Kazakhstan have also each made a number of top division appearances since the early 1990s. Less frequent top pool appearances have been made by Austria, Denmark, France, Italy, Japan, Norway, Poland and Ukraine.

For the 2018 championships to be held in Buffalo, the participating teams will be Belarus, Canada, the Czech Republic, Denmark, Finland, Russia, Switzerland, Slovakia, Sweden, and the United States.
