British baseball, also known colloquially in Wales as Welsh baseball (Welsh: Pêl Fas Gymreig), is a bat-and-ball game played in Wales, England, and to a lesser extent in Ireland and Scotland. The game emerged as a distinct sport in Merseyside, Gloucester and South Wales at the end of the 19th century, drawing on the much older game of rounders. Teams in all locations played under the codified rules created by the National Rounders Association (later renamed as the (English Baseball Association), with the game in Wales locally organised first by the South Wales Baseball Association, (still playing under English Baseball Association rules), who in turn were replaced by the Welsh Baseball Union. The Irish Baseball Union were formed in 1933. Both the English Baseball Association and Welsh Baseball Union are members of the International Baseball Board.
