Rule, Britannia originated in 1740 as part of the masque Alfred, with lyrics by James Thomson and music by Thomas Arne. Over time, its chorus became one of the best-known patriotic songs associated with Britain. Online, short clips spread through meme edits, national stereotype jokes and reaction videos, where the music quickly signals Britishness. It remains popular because the opening and chorus are instantly recognisable and can be used either earnestly or with heavy irony, depending on the edit.
