The company's growth under the management of David Webster from modest beginnings to parity with the world's greatest opera houses was recognised by the grant of the title "The Royal Opera" in 1968. Under Webster's successor, John Tooley, appointed in 1970, The Royal Opera prospered, but after his retirement in 1988, there followed a period of instability and the closure of the Royal Opera House for rebuilding and restoration between 1997 and 1999. The 21st century has seen a stable managerial regime once more in place.
