Once upon a time, this language knew the best of times, and it was spoken by all the territories of the Holy Roman Empire. Now, although the Latin language is considered dead, it is the official language of the Holy See, the Order of Malta and the Vatican City State. Divine services are still conducted in it, and until the end of the 20th century this language remained the language of science.
As a matter of fact, before the French Revolution, many more people knew Latin - all teaching in universities was conducted in Latin, until, finally, the revolutionary spark set the stage for the translation of lectures into their native languages. In the second half of the 20th century, the position of Latin weakened once again - Catholic churches were allowed to hold services in national languages. What do we have in the 21st century? Terminology, quotes in public, tattoos on elbows, and residual use in science and worship - that's all the remnant of the former strength of the language of the great empire of the past. The Latin language died out due to the collapse of the Roman Empire, but I would not mind learning it because the phrases in it sound very beautiful.
