1920–21 Yorkshire Cup

The 1920–21 Yorkshire Cup was the thirteenth occasion on which the Yorkshire Cup competition had been held. This year saw a new name on the trophy, when previously twice beaten finalists (1906 and 1911), Hull Kingston Rovers won the  trophy at the  third attempt by beating close neighbours and fierce rivals Hull F.C. by the score of 2–0 in the final. The match was played at Headingley, Leeds, now in West Yorkshire. The attendance was 20,000 and receipts were £1,926. This was the first of only three meetings between the teams which would take place in the finals in the long history of the tournament

Background
The Rugby Football League's Yorkshire Cup competition was a knock-out competition between (mainly professional) rugby league clubs from the  county of Yorkshire. The actual area was at times increased to encompass other teams from outside the  county such as Newcastle, Mansfield, Coventry, and even London (in the form of Acton & Willesden. The Rugby League season always (until the onset of "Summer Rugby" in 1996) ran from around August-time through to around May-time and this competition always took place early in the season, in the Autumn, with the final taking place in (or just before) December (The only exception to this was when disruption of the fixture list was caused during, and immediately after, the two World Wars).
