Chess is one of the most popular board games in the world today. It involves two players, and requires strategizing and tactical planning. The game of is not a modern invention, and there is a good deal of controversy among historians regarding the true time and place of the emergence of chess. Many countries claim to have invented it. However, most historians trace its origins back to northern India or Afghanistan sometime around 600 AD. The most common theory is that the form of we play today evolved from a game called 'Chaturanga', which was played in ancient India. Since the Arabic, Persian, Greek, Portuguese and Spanish words for are derived from Chaturanga, it is the most accepted view that originated in India. However, another theory claims that evolved from a game of 'Xiangqi' that existed in China in the 2nd century BC.

Regardless of its origin, eventually spread all over the world. In so doing, it took on regional terms. When it entered the Islamic countries, the names of the pieces were retained in their Persian form, but the name of the game itself became 'Shatranj'. When the game was introduced to Europe, terms were replaced by English words; the 'Shah' became 'King', the 'Begum' became 'Queen', for example.

The entrance of into Europe was marked by the enhancement of the powers of the 'Queen' piece. Early on in European chess, the pieces had very limited movement. The Bishop could move forward only by jumping two steps diagonally, and the Queen could move only one step forward diagonally. Pawns could move just one space at a time during the first move instead of the customary two steps on the first move that we see today. There was no castling, either. By the late 15th century, the modern rules for the basic moves of the pieces had been added--Pawns could move two squares on their first move, Bishops could move as they do nowadays, and the Queen became the most powerful of all the pieces. The current rules were finalized in the early 19th century.
