History
Ancient Cadasan started out as a dialect of Malay. Starting in the 10-11th centuries, Classical Cadasan was used, and it started to diverge from Malay. Classical Cadasan was gradually abandoned in the 13-14th centuries, however it was used as a literacy language until the fall of the Cahaya dynasty in 1936. From the 14th centuries to the 17th, Middle Cadasan was used, after which it started to shape into Modern Cadasan, the language used today.

However, even though Cadasan was made the official language of Cadasa in 1936, it was reserved for the elite and government officials, and education of Cadasan in schools were poor. Most Cadasans spoke their own languages, like Tamil or Chinese. It wasn't until the 1960s that then-president Aarush Chiu vigorously promoted Cadasan as the lingua franca.
