What language is canto from?

I'm curious to know, where does the language Cantonese, also known as Canto, originate from? Is it rooted in a specific region or cultural background? I'm particularly interested in understanding the linguistic origins of this dialect, as it seems to have a rich history and a distinct place in Chinese language and culture. Can you provide some insight into its origins and any unique features that set it apart from other Chinese dialects?
