[3] In King Ottokar's Sceptre, Tintin reads a Syldavian tourist pamphlet that reveals the early history of Syldavia and its relationship with Borduria.

In The Calculus Affair (1956), Borduria is depicted as a stereotypical Eastern Bloc country with its own secret police (ZEP) (led by Colonel Sponsz) and a military dictator, Marshal Kûrvi-Tasch.

A statue of Kûrvi-Tasch appears in front of a government building, in which he wears a moustache similar to Joseph Stalin's and gives a Nazi-like salute.

The Bordurian military of this period is depicted as technologically inept—unable to stop a stolen tank commandeered by Tintin and his companions as a result of defective mines and anti-tank guns.

In Tintin and the Picaros (1976), the South American banana republic of San Theodoros, ruled by General Tapioca, has formed an alliance with the Bordurian government, which has sent him military advisors, including Colonel Sponsz.

Several Central European countries such as Hungary, Croatia, Albania and Romania were ruled by fascist governments before or during World War II.

Due to the nature of its government and its military's weaponry, Borduria was most likely an affiliate of the Axis during World War II, although there is no explicit mention of that in the books.

Unlike Syldavian, it uses the Latin alphabet exclusively, and makes heavy use of the digraph sz (possibly borrowed from Hungarian), as well as ô.
