Jacques Antoine Bernard (November 4, 1888 – October 26, 1952), was a French writer and editor of the Mercure de France, an important literary journal.

Born Jacques Alexandre Antoine Bernard,[1] on April 11, 1888 in Paris, France, he was the son of Laure-Theresa Cros-Bernard, fourth sovereign of the Kingdom of Araucania and Patagonia.

[6] On August 28, 1873 the Criminal Court of Paris ruled that Antoine de Tounens, first "king of Araucania and Patagonia" did not justify his status of sovereign.

[7] Since the death of Antoine de Tounens, some French citizens without familial relations declared themselves to be pretenders to the throne of Araucania and Patagonia.

[8] The pretenders to the throne of Araucania and Patagonia are called monarchs and sovereigns of fantasy,[9][10][11][12][13] "having only fanciful claims to a kingdom without legal existence and having no international recognition".
