It's a movie based on a book called The Last Duel by Eric Jager based on the famous last duel officially sanctioned by the King in the late 14th century France. The movie is an adaptation and is said to follow the book fairly closely.

There are varying accounts of the duel and what exactly transpired between the characters.

My question is not just restricted to the duel itself or the events that lead up to it, but on the overall film. Are the costumes accurate to the time period? The political setup under the king? The lifestyle depicted of lords and knights as well as attitudes towards women? Things like that.

I thought it was a fascinating film and provided good insight to the duel itself as well as life in 14th century France. At least it amde me interested in discovering more.
