The team play in League One , the third tier in the English football league system, following their relegation from the Championship in the 2016-17 season.
Founded in 1925 as a merger between Rotherham Town (1899) and Rotherham County (1870), the club’s colours were initially yellow and black, but later evolved into the more traditional red and white. Rotherham United play their home games at New York Stadium, a 12,000 capacity all-seater stadium, having previously played since its foundation at Millmoor for 101 years. Joining the football league back in 1925, Rotherham spent the first 25 years of their time in Division Three North, the lowest level of the football league, finally gaining promotion to Division Two at the end of the 1950–51 season.
