White Wallachia
White Wallachia was a Byzantine term for the region between the Danube and the Balkan mountain. It is not to be confused with the Great Wallachia or the Little Wallachia. It was also referred to as Asen's Wallachia in the records of the French knights Guillaume de Rubrouquis and Geoffroy de Villehardouin. It was called white to otherwise distinguish from the "Black Wallachia", which was Moldavia.
An account stated that the color in the appellation is attributed to the white sheep skin cap and cloak worn in winter. Those who belong to Black Wallachia wore black cap of the same material.
