From 1880 onwards, more and more Dutch-speaking people became bilingual and passed only French on to their children, resulting in a rise of monolingual French-speakers after 1910. Halfway through the 20th century, the number of monolingual French-speakers carried the day over the (mostly) bilingual Flemish inhabitants.[39] Only since the 1960s, after the fixation of the Belgian language border and the socio-economic development of Flanders was in full effect, could Dutch stem the tide of increasing French use.[40]
