Chess is a game that has evolved over centuries, with various rules and strategies being introduced and refined over time. One such rule that adds an interesting twist to the game is “en passant.”
When Was En Passant Added to Chess?
En passant was introduced to chess in 1561 during the major European rule revisions.
It was codified into the rulebook in 1880.
En passant is a special pawn capture that can only occur under specific circumstances.
Below we look deeper into the history of en passant and when it was added to chess.
The Origins of Chess
Before looking into the history of en passant, it is essential to understand the origins of chess itself.
The game of chess, as we know it today, has its roots in ancient India, where it was known as “chaturanga.”
Chaturanga was played on an 8×8 board and featured four different types of pieces: the king, the elephant (later replaced by the bishop), the horse (later replaced by the knight), and the foot soldier (later replaced by the pawn).
Chaturanga spread to Persia, where it underwent further modifications and became known as “shatranj.
Shatranj gained popularity in the Islamic world and eventually made its way to Europe during the Middle Ages.
The Evolution of Chess Rules
As chess spread across different regions and cultures, various rules were added or modified to enhance gameplay.
The rules of chess continued to evolve until the modern version we play today emerged.
One such rule that was introduced during this evolution was en passant.
Early Chess and the Absence of En Passant
In the early versions of chess, such as chaturanga and shatranj, en passant did not exist.
The pawns in these early versions could only move one square forward at a time, so the rule was not relevant.
Eventually pawns were given the option to advance two squares on the first move to speed games up.
The Emergence of En Passant
The first mention of en passant can be traced back to the 15th century in a book called “Libro de los juegos” (Book of Games), written by Alfonso X of Castile.
However, the rule described in this book differs slightly from the en passant rule we know today.
In Alfonso X’s version, if a pawn advanced two squares from its starting position and landed beside an opponent’s pawn, the opponent had the option to capture the pawn “en passant” on their next move.
This early version of en passant allowed the opponent to capture the pawn immediately after it moved two squares forward.
En Passant in Modern Chess
The en passant rule we are familiar with today was invented in 1561 and standardized in the rulebook in 1880.
The rule states that if a pawn moves two squares forward from its starting position and lands beside an opponent’s pawn, the opponent has the option to capture the pawn “en passant” on their next move.
This capture can only be made on the very next move; otherwise, the opportunity is lost.
The introduction of en passant added a new layer of strategy to the game.
It allowed players to create tactical opportunities by luring their opponents into advancing their pawns, which could then be captured en passant.
