The origins of the French Defense can be traced back to the 18th century, although it only really gained prominence and recognition as a distinct opening in the 19th century.
The name “French Defense” itself comes from the first recorded game in which it was played, which was part of a correspondence match between the cities of London and Paris in 1834. The opening was named “French Defense” because the Parisian players victoriously played it, thanks to team member Jacques Chamouillet who convincingly advocated for it.
Although the French Defense wasn’t as extensively studied or played in earlier times as some other openings, its popularity grew throughout the 19th and 20th centuries. Grandmasters like Akiba Rubinstein, Viktor Korchnoi, and more recently Alexander Morozevich, and Teimour Radjabov, have been associated with this opening and have contributed to its theory and development. Today, according to the Chessbase online database, it is Black’s third most popular response after 1…c5 and 1…e5.
