Peacekeeper achievment

I know that cheevos are bugged right now anyway, but I'd still like to know how to get this one.

If you are a pacifist, you can only declare liberation wars to re-capture your former territory. If you're fanatic pacifist you can't declare war at all (I think).

The only way I was aware of to change another empire's ethics was to declare war and demand the liberation of those planets, which creates a new empire with the same ethics as your own.

It's been awhile since I played so if more gameplay came in recent patches and/or utopia that allow other ways to change your own/other empire's ethics, I am not aware of it.

Create a game with only one AI and pray they are paficist or something?
There is probably another way, but that what comes to mind first.

Migration treaties can send your pacifist population into other empires, to plant the seeds of a faction that will want peace. When someone attacks you, you can still make liberation war demands that will result in new pacifist empires. Forming a federation means that you can block the other members from declaring any wars...and long periods of peace will mean that their population will start shifting to pacifism.

I haven't pulled it off myself, but in theory the tools are there. It is just a question of figuring out how to use them effectively and then getting lucky enough to pull it off.

If you want to just get the Achievement, the easiest way I know of is create a handful of Pacifist empires and click the little Phoenix symbol by them in the choose your empire screen to put the lock symbols on them, so they will force spawn into your game

Start a game with only one AI, and use a Pacifist Enpire yourself, and if one of your pre-created ones spawn in as the other Enpire you should get it immediately (once achievements are fixed at least)
