Mahjong is a tile-based game that was developed in China during the Qing dynasty and has spread throughout the world since the early 20th century. It is commonly played by four players (with some three-player variations found in Japan, South Korea and Southeast Asia). The game and its regional variants are widely played throughout Eastern and South Eastern Asia and have also become popular in Western countries.

The Qing dynasty, officially the Great Qing, was the last imperial dynasty of China. It was established in 1636, and ruled China from 1644 to 1912. It was preceded by the Ming dynasty and succeeded by the Republic of China. The Qing multi-cultural empire lasted for almost three centuries and formed the territorial base for modern China. It was the fifth largest empire in world history in terms of territorial size.
