Charlotte, Grand Duchess of Luxembourg (ruled 1919-1964) married a cadet of the Parmese line and thus her successors, who have ruled Luxembourg since her abdication in 1964, have also been members of the House of Bourbon. Isabel, Princess Imperial of Brazil, regent for her father, Pedro II of the Empire of Brazil, married a cadet of the Orléans line and thus their descendants, known as the Orléans-Braganza, were in the line of succession to the Brazilian throne and expected to ascend its throne had the monarchy not been abolished by a coup in 1889.
