Chess World Championships

The following studies contain every game from "Official" Chess World Championships. They should be relatively easy to data-mine using the Lichess API. Obviously, over more than a century there is some controversy over which matches or tournaments qualify. Matches and tournaments that are not in the main list here but some might consider legitimate will be given an "Apocrypha" section at the end.

Matches marked with ^ have not been published as Lichess studies yet.

Of note:

Some players before 1886 like Morphy or La Bourdonnais were called "World Champion" and there is no objective measure of which of their matches "count." The following list is meant to show what is generally accepted as the World Championship lineage starting with Wilhem Steinitz and ending with Ding Liren.
Lasker played three matches against Janowski over the course of 1909 and 1910, only the third match is considered a World Championship match here. The second match has been called a World Championship match by some sources, but prominent chess historian Edward Winter disagrees.
The World Championship was decided by a multi-player tournament instead of a 1v1 match on 2 occasions; 1948 and 2007. Those studies contain all games from the event from all players
Garry Kasparov broke away from FIDE and organized his own match for the world title three times in 1993, 1995, and 2000. FIDE continued to run its own world championship during this time, but the overwhelming majority of chess players consider Kasparov to be the legitimate champion of this era.
The 2016 and 2018 matches were decided by rapid tiebreak games. These games have been included in Apocrypha instead of the main study for consistency.
