Floris - De drie narren
https://en.wikipedia.org/wiki/Floris_(TV_series)
Floris is a 1969 Dutch action television series starring Rutger Hauer and Jos Bergman, written by Gerard Soeteman, and directed by Paul Verhoeven.
Concept
The success of television series like the British Ivanhoe, the French Thierry La Fronde and the Flemish Johan en de Alverman inspired Carel Enkelaar [nl], manager of NTS (forerunner of NTR) to make a similar series, set in the Netherlands. It was written by Gerard Soeteman. The series was filmed in black and white, and has been aired in reruns through the years. It has also been shown in East Germany and (dubbed in English) in Scotland.
Storyline
In the early 16th century, during the Guelders Wars (1502-1543), the knight Floris van Roozemond (spelling varies with o/oo, s/z and d/dt), accompanied by the Indian Sindala (Bergman), returns home from a trip around the world only to find his castle occupied by Maarten van Rossum, the commander in chief of Charles, Duke of Guelders. Charles, who controls Guelders, is involved in a power struggle against Philip the Handsome who rules the Burgundian Netherlands, the rest of the Low Countries. Floris had so far been neutral due to his absence, but after he finds his castle stolen, he sides with Wolter van Oldenstein, who is allied with Burgundy against Charles. Charles and Maarten are aided by the Frisian pirate Greate Pier partly as an ally, and partly to do the dirty work.
