Oc Languages (Occitan)

The Oc languages are spoken mainly in southern France, but also in Italy and Spain. They are called that way because "oc" is the word used for "yes". Catalan, in Spain, despite being very similar, uses "si", but "oc" was still used in the middle ages. But I'll talk about catalan later.
Since virtually all Oc languages are endagered and also relatively similar, they are currently called Occitan, as a single language composed by several dialects. It used to be known as lemosin or provençal before the adoption of the broader term "Occitan".
The most known dialects are lemosin, gascon, languedocien, and provenzal. It was in this languages that the first trobadores made they work, before being adopted by galician-portuguese. Richard the Lion Heart was known to be a native speaker of lemosin and wrote poetry in this language along with french (no english though).
Occitan has no official status in France, with only a few steps taken towards recognition. It has co-officiality in some small areas in Italy, along with italian, and in the Aran Valley in Catalonia, Spain, as "aranese" (a dialect of gascon) along with catalan and spanish.
