The Royal Calcutta Turf Club (RCTC) is a horse racing organisation which was founded in 1847 in Calcutta, British India (now Kolkata). Horse events and sports were initially organised for the British cavalry at Akra before they were moved to the Maidan. The RCTC became the foremost horse-racing organization in India during the British Raj. At one time it was the governing body for nearly all racecourses in the subcontinent, defining and applying the rules governing the sport. During its heyday, RCTC-organised races were among the most important social events of the bigwigs' calendar and were opened by the Viceroy of India. Still a private club, the RCTC operates Kolkata Race Course in the Maidan.
