What country is Leroy Merlin from?

I'm curious to know, which country does Leroy Merlin hail from? I've heard quite a bit about this company, but I'm not entirely sure of its origins. Is it a French company, perhaps? Or could it be from some other European nation? I'm eager to learn more about the roots of this business and how it has grown to become such a well-known name in the industry. If you could shed some light on this matter, I'd be very grateful.
