Posses are created in multiplayer free roam games by inviting players. Some players join up in consistent posses and treat them as a clans or guilds. In fact the Red Dead Wiki has our very own posse of know-it-alls.

If you want to create a Posse page, just go to this and type in your Posse's name and click "create".

Hope this helps!
