Belgian historian Jo Gerard recounts that potatoes were already fried in 1680 in the Spanish Netherlands, in the area of "the Meuse valley between Dinant and Liège, Belgium. The poor inhabitants of this region had the custom of accompanying their meals with small fried fish, but when the river was frozen and they were unable to fish, they cut potatoes lengthwise and fried them in oil to accompany their meals."
The Dutch concur with a Southern Netherlandish or Belgian origin when referring to Vlaamse fritten (Flemish fries). In 1857, the newspaper Courrier de Verviers devotes an article to Fritz (assumed pun with frites), a Belgian entrepreneur selling French fries at fairs, calling himself "le roi des pommes de terre frites". In 1862, a stall selling French fried potatoes (frietkot) called "Max en Fritz" was established near Het Steen in Antwerp.
A Belgian legend claims that the term "French" was introduced when British or American soldiers arrived in Belgium during World War I, and consequently tasted Belgian fries. They supposedly called them "French", as it was the official language of the Belgian Army at that time. Another story goes that just-parachuted soldiers near the border were delighted to find a fritkot nearby and erroneously believing they were in France, called the delicious food "French Fries".<
"Frites" became the national Belgian snack and a substantial part of their national dishes — making the Belgians their largest per capita consumers in Europe, and their "symbolic" creators.
