Hola, que bueno que hay otr@ mexican@ por acá!
We don't have a house currently reigning in Mexico but we do have a history of Royalty, not only the two empires, but I guess we could count the Aztec Kings and the Virreyes we had. When you are in Mexico City, I hope you can take a tour at the Chapultepec's castle and see the stuff about Carlota and Maximiliano
