KHL

The league formed from the Russian Superleague (RSL) and the champion of the 2007–08 season of the second division, with 24 teams: 21 from Russia and one each from Belarus, Latvia, and Kazakhstan. The teams were divided into four divisions, based on the performance in previous seasons.^[]

The start of the fourth season was overshadowed by the 2011 Lokomotiv Yaroslavl plane crash on 7 September 2011 in which almost all members of the team Lokomotiv Yaroslavl lost their lives shortly after take-off for their flight to their season-opening game in Minsk. The Opening Cup game in Ufa, which was already underway when news of the disaster arrived, was suspended. In memory of the disaster, 7 September remained a day of mourning on which no KHL regular-season games took place, until after the 2017–18 KHL season. Journalist Vsevolod Kukushkin acted as the first press secretary for the league, after it evolved from the Superleague.

After the 2022 Russian invasion of Ukraine, the National Hockey League suspended operation of its Memorandum of Understanding with the KHL. An NHL memo instructed NHL teams to "immediately cease all dealings [direct or indirect] with the KHL and KHL Clubs [and all representatives of both], as well as with player agents who are based in and continue to do business in Russia."

In the 2009–10 season, Avtomobilist Yekaterinburg joined the KHL and Khimik Voskresensk was transferred to a lower league. In the 2010–11 season, Yugra Khanty-Mansiysk joined the league.

After several attempts by teams from Central Europe and Scandinavia to join the KHL, expansion beyond the borders of the former Soviet Union was finally realized in 2011. Lev Poprad, a newly founded team based in Poprad, Slovakia was admitted to the league. But after only one season, Lev was replaced by a team of the same name, Lev Praha, from Prague, Czech Republic, while Slovan Bratislava from Bratislava, Slovakia and Ukraine's Donbass from Donetsk joined the KHL as expansion teams for the 2012–13 season. Lev and Slovan qualified for the playoffs in their first KHL season.

In 2013, Medveščak from Zagreb, Croatia, previously playing in the Austrian Hockey League, and Russian expansion team Admiral Vladivostok joined the league, thus expanding the league even further. The league comprised 28 teams during the 2013–14 season, of which 21 were based in Russia and 7 located in the other countries.

In 2014, Finnish team Jokerit from Helsinki, Lada Togliatti (which previously played in the league), and newly created team HC Sochi joined the league. However, HC Donbass did not play in the league for the 2014–15 season, due to the Russia's involvement in the Donbas war in Ukraine, but had intended to rejoin later. Two other teams, Lev Praha and Spartak Moscow, also withdrew from the 2014–15 season due to financial problems.

Prior to the 2015–16 season, Atlant Moscow Oblast withdrew from the KHL due to financial issues, while Spartak Moscow returned after a one-year hiatus. The newly created Chinese club HC Kunlun Red Star from Beijing was admitted for the 2016–17 season. Kunlun was established as part of China’s efforts to prepare a competitive national team for the 2022 Winter Olympics in Beijing.

Prior to the 2017–18 season, Medveščak Zagreb withdrew from the league to rejoin the Austrian league and Metallurg Novokuznetsk was sent down to the VHL.

After the end of the 2018–19 season, HC Slovan Bratislava withdrew from the KHL due to financial issues to rejoin the Slovak Tipsport Liga.

On 24 February 2022, Finnish club Jokerit announced the team would withdraw from the league for the remainder of the season, including the playoffs, due to the 2022 Russian invasion of Ukraine. On 27 February 2022, Latvian club Dinamo Riga announced that they too would withdraw for the same reasons. Prior to the 2023–24 season, HC Lada Togliatti rejoined the KHL.
