Conquian is a card game whose origins are in dispute. Some believe the game originated in Spain hundreds of years ago, and was then brought to Mexico. Others strongly believe the game actually originated in Mexico in the mid-1800s. It was first described as Coon Can in 1887 and then in detail in R. F. Foster's Hoyle in 1897. According to David Parlett, it is an ancestor to all modern rummy games, a kind of proto-Gin Rummy. He also notes that the 1920s American card-game writer Robert F. Foster “traces Conquian back to the early 1860s.”
