TV21 and the National Society "Tradition", Regional Branch "8th Primorski Infantry Regiment", are working together on a documentary dedicated to the 8th Primorski Infantry Regiment – one of the most emblematic formations in Bulgarian military history.

The film will trace the regiment's combat history and key role during the Serbo-Bulgarian War, the Balkan Wars and the First World War.

The project combines archival sources, expert historical commentary and contemporary documentary storytelling.

The documentary is part of TV21's mission to create content with cultural, historical and social value.
