Ownership of the territory changed frequently during the medieval period, and Bohain continued to find its lordship disputed in the wars of the early modern period. Traces of fortifications (ditches, cannonballs, bases of walls) can not only be found near to the primary school, but also in other spots of the town. In its past, Bohain being unequivocally incorporated within France, industry and trading developed and the town became a major center for the textile industry. In parish records from the 17th century one of the most frequent occupations registered was that of "mulquinier", although the term is generally used to refer to fine fabrics craftworkers, it seems likely that in these very same records the term was also applied to anyone who worked at the weaver's trade. It is recorded that
Napoleon ordered a Bohainais weaver to work for the
Empress Joséphine. The old textile factories have closed one after another, but weaving is still considered as a local tradition. It has been reported that the Lord (seigneur) of Bohain gave up
Joan of Arc to the English during the
Hundred Years' War. ==Population==
