Le Sceptre d'Ottokar
In "King Ottokar's Sceptre", Tintin reads a Syldavian tourist pamphlet that reveals the early history of Syldavia and its relationship with Borduria. In 1195, Syldavia was annexed by neighbouring Borduria due to the weakness of King Muskar II, and was under its rule until 1275, when Baron Almaszout drove the Bordurians away and established himself as King Ottokar I. In the later "Tintin" stories, this ancient rivalry continues with the Bordurians continually trying to invade or undermine Syldavia.
