When Knighthood Was in Flower is a 1922 American silent historical film directed by Robert G. Vignola, based on the novel by Charles Major and play by Paul Kester.

[2][3] Mary Tudor is forced by her brother Henry VIII to marry Louis XII as part of a peace agreement, but she falls in love with Charles Brandon.

[4][5] According to Variety, William Randolph Hearst launched "the most expensive and extensive campaign that has ever been organized for anything theatrical", with over 650 billboards in New York, 300 subway advertising placards, special booths in department stores that sold souvenir books, and a dazzling string of electric signs that pervaded Times Square, upon which Will Rogers quipped that Davies's next film would be titled When Electric Light Was in Power.

[8] Robert E. Sherwood defined the film "gorgeously beautiful [...] flashily romantic and stirringly impressive",[9] ranking it as one of the best pictures of the year[10] and appreciated Vignola's "genius for lighting and composition".

[14] The Motion Picture Guide praised the film for its "tremendous production values, excellent direction, a good script, and an outstanding cast", giving it three out of four stars.

[17] British art dealer Joseph Duveen stated the film setting was "the most stupendous reproduction of Henry the Eighth court life that has ever been achieved — a marvelous piece of artistry".
