Can someone tell me shortly why Belgium speaks french? I understand they speak french and flemish but I mostly looking for the entire backstory when/why Belgium became a country with french as their official language. And please don't add too much extra stuff, keep it as simple as possible lol

The capital city of Brussels originally shifted to speaking predominantly French for the same reasons the newly independent Belgium did: because it was considered the most prestigious language in Belgium at one time, both for getting access to higher education and well-paying jobs

Politically the country was once polarized on matters of religion and it has faced new divisions over differences of language and unequal economic development. This ongoing antagonism has caused far-reaching reforms since the 1970s and repeated governmental crises. It is now divided into three regions: Flanders (Dutch-speaking) in the north, Wallonia (French-speaking) in the south, and bilingual Brussels in the middle. There is also a German-speaking population along the border with Germany.German is the third official language of Belgium.
