I’m not sure why, but people usually assume that medieval people were dirty. Historians generally consider later periods, especially the seventeenth and eighteenth centuries, those days of powdered wigs and elaborate costumes, as being a time when personal hygiene was at its nadir. Medieval cities often had public baths and there is much evidence of cleanliness in contemporary illustrations.

Bathers used soap, often from Castile, knew about deodorants, and employed perfumes.
The heroine of The Viscountess and the Templars, Ermengarde of Narbonne enjoys a bath in the novel. You will have to read the book to find out why it was important.
