Koenigsmark is a 1935 British-French drama film directed by Maurice Tourneur and starring Elissa Landi, John Lodge and Pierre Fresnay.

In his absence, the Princess battles for control of the state with her brother-in-law Frederick, particularly when news arrives from Africa that Grand Duke Rodolphe has died of disease.

Vignerte is working on research into the tragic historical romance between Sophia Dorothea and Philip Christoph von Königsmarck.

As the outbreak of the First World War approaches, the Princess drives Raoul to safety from arrests across the border, and then returns to confront Frederick.

Faced with exposure he shoots himself, at which point the Princess abdicates, not wishing to take part in the war against Russia or France.
