El cetro de Ottokar
"King Ottokar's Sceptre" (written in 1939 by Hergé) depicts an unsuccessful Bordurian attempt at staging a "coup d'état" against Syldavia, trying to remove the king and invade the country with the support from Syldavian sympathizers. The sceptre is stolen, which would force the King to abdicate, however Tintin returns it in time. The Bordurians then withdraw their troops 15 miles from the borders to prove their peaceful intentions.
