The Royal Over-Seas League (ROSL) is a self-funded, non-profit Commonwealth organisation which offers clubhouse facilities to members, organises Commonwealth art and music competitions and develops joint welfare projects with specific countries.
ROSL, originally the Over-Seas Club, was founded in 1910 by Sir Evelyn Wrench to foster international understanding and friendship. In 1960, HM Queen Elizabeth II granted the title "Royal" to mark its golden jubilee. Today, the league has 60 branches, reciprocal clubs and representatives in 78 countries with a worldwide membership of 20,000.
A Thailand branch of Britain’s Royal Over-Seas League (ROSLT) was formally inaugurated on the 14th of November 2005, as the organisation celebrated its 95th anniversary.
