The Royal Over-Seas League (ROSL) is a non-profit members’ organisation with international headquarters based in its clubhouse in central London, England. It is also a major supporter of the arts, most notably with its prestigious annual music competition. Founded by Sir Evelyn Wrench in 1910 as the Over-Seas Club, it was given a Royal Charter of Incorporation in 1922 and Queen Elizabeth II granted the title "Royal" to mark its golden jubilee in 1960.
