Cricket is one of the most popular sports in England, and has been played since the 16th century. Marylebone Cricket Club, based at Lord's, developed the modern rules of play and conduct. The sport is administered by the England and Wales Cricket Board and represented at an international level by the England men's team and England women's team. At a domestic level, teams are organised by county, competing in tournaments such as the County Championship, Royal London One-Day Cup, T20 Blast and the Women's Twenty20 Cup. Recent developments include the introduction of a regional structure for women's cricket and the establishment of The Hundred for both men's and women's cricket. Recreational matches are organised on a regional basis, with the top level being the ECB Premier Leagues.
