Creating an alliance requires a very clear vision of what you want from it. I made a one-man alliance and it worked out for quite a long time, but that was only because I had the power of fortification and a goal of hitting salty people with missiles. If you want to make an alliance, then power to you, but these days you need the capacity to offshore resources and cash, discord for bots and coordination, and enough of an internal culture that you can survive nuke turrets and poaching.
Right now your "Teutonic Knights" has exactly zero of those things except a basic discord, so fix that please before you start recruiting and giving new players a misrepresentation of how the game can really work.
