What is a Métis Indian?

Could you please elaborate on the concept of a Métis Indian? I'm curious to understand the historical and cultural background of this term, as well as its significance in modern society. Is it a distinct ethnic group with its own traditions and practices, or is it a broader classification that encompasses various indigenous populations? I'm particularly interested in learning about the experiences and perspectives of Métis Indians today, and how they navigate their identity in a rapidly changing world.
