Kinda yes, in addition it was the language in which 3 of the most important Italian poets (Dante, Petrarca and Boccaccio) wrote. To be honest, even if Florentine became the official Italian language soon after Italy was unified in 1861, it wasn't until 1960s that Italians started to speak it everyday thanks to radio and TV. In addition, I would argue that the use of dialects is still a thing here (and these dialects not only are very different languages from Florentine, but they drastically differ within a range of 10 km from one town to another)
