The town was granted a commercial charter by the French crown in 1180 and became an internationally important location for banking and trade. The wool industry of Arras, established in the 4th century, became of great importance during the Middle Ages. Already in the third century Romans had lauded about the quality of wool from Tournai and Arras. By the eleventh century Arras was the leading city and trading hub of the wool industry. This prominence would eventually shift towards areas north of Arras, and cities such as Lille, Douai and Saint-Omer, followed by Ypres and eventually Bruges would become the centres of the wool industry and trade. However, by the 14th century Arras still was renowned and drew considerable wealth from the cloth and wool industry, and was particularly well known for its production of fine tapestries—so much so that in English and Italian the word "Arras" ("Arazzi" in Italian) was adopted to refer to tapestries in general. The patronage of wealthy cloth merchants ensured that the town became an important cultural center, with major figures such as the poet Jean Bodel and the trouvère Adam de la Halle making their homes in Arras.
