You may want to check the 'Mega Evil Empire' setting in settings.txt (in the data folder)...

To elaborate a bit: The "Mega Evil Empire" settings determine how strong the first place empire has to be to get all the AIs to unite against it. It's meant to make the game more challenging in the late stages; some people prefer to just turn it off.

Is this union endless?At least I haven't found an end.

[Fyron]

It will stop if you fall below the MEE threshold (though you will still have to try to get peace with each empire manually).

[dogscoff]

You are bread, they are gravy.

If you've hit MEE, then you're powerful enough to attack those remaining empires, crush their fleets, sweep aside their defences, conquer their planets and have their humbled leaders dragged in shackles before your throne. Oh, and you should start work on a Ringworld or two, just to pass the time.

That's the best way to 'end the union.'
