The show is set during the early stages of the Guelders Wars, before the death of Philip the Fair of Burgundy in 1506. While Maarten van Rossum's exact birth date is unknown, it was probably shortly before 1490, which would make him a teenager during Philip's reign. Pier Gerlofs Donia also did not become a commander before 1515, so both villains imply the series should be set during the reign of Philip's successor Charles.
