Just something that's always cropped up in my various readings is the fact that romanian is a romance language with some routes in Latin. Now I know about the 4th crusade that conquered the region and gave it the name Romania. However what's always puzzled me is that they were only there for one or two hundred years. Was that really enough time to ingrain latin into the local dialect so much or was there some other reason.
Thanks
What you are referring to was located in modern day Greece and Turkey and has nothing to do with the Romanian language. The crusaders sacked Constantinople, the capital of what is today called the Byzantine Empire but was then known as the Roman Empire (different from the ancient Roman Catholic) and established a western/Catholic one, which we call today the "Latin Empire" but at the time it was also considered to be "roman". Both the crusaders and the locals called the region "Romaniae" but the people were Greek speakers and remained so, the crusaders did not latinise the region.
Modern day Romania, where Romanian is spoken, is located north of the Danube and is unrelated to these events. See the comments by u/Theghistorian and /u/Spoonfeedme as well as the references to older threads in:
