It is the oldest game of intellectual skill that is still played today and that is because it is fun.
However on the board of chess there is more than just a fun game there is a historic lesson that can give you a peek into the lives and ceremony of the people who lived in the middle ages.
Even though the type of chess that me and you play today originated in Europe.
Its predecessor originated in India.
From India it spread to Persia.
Persia was invaded by the Arabs and the Moors who in turn invaded southern Europe and Spain and with this conquest they brought a game.
Originally it wasn't very popular in Europe this quickly changed when the names of the pieces were adapted.
Each country that took the game had different names.
For instance the Bishop in India is a war elephant and the castle (rook) is a chariot and the queen was a minister.
The Pawns in a chess game represent the common foot soldiers or serfs.
These were considered property.
This is why pawns were so expendable and are often used as a sacrifice to get a shot off at the more powerful enemy forces.
The rule of pawn promotion was the fact that a hero in war would be promoted.
Originally the queen was a much weaker unit and so the pawn could be promoted to a queen and when the queen got new rules that made it more powerful the rule that a pawn could become a queen stayed.
The castle represents walls and well, castles and forts and such.
So the fact that it could move as far as it wants left, right, forward, back makes sense since this makes a wall.
Also since it represents a home it also represents safe haven which led to the rule of castling since this gives safe haven to the king.
The bishops are closest to the king and queen since often the bishops were the kings closest adviser's.
The Knight represents a trained soldier or a hero and as everyone knows a true hero fights on the front lines.
This is why the Knight could jump over other pieces and there for lead from the front.
Or it is arguable that this represents the Knight as being expendable and can more easily jump into danger to protect the king.
You know the chess boards that can fold up so that they are easier to carry around.
The inventor of this type of board was actually a bishop who loved to play chess.
Chess was actually illegal for a little while since the church had put a ban on gambling but the bishop loved playing chess and so disguised his board as a book.
