Take the 2-minute tour ×  Often my people become unhappy about
the unwieldy size of my empire. Is there any way to just destroy
the population on an opposing planet, rather than taking control
of it?  share|improve this question add comment  1 Answer  Not
that I know of. You're better off doing research to solve their
unhappiness; in the Expansion and Colonization (Down) tree,
there are researches to lower Expansion Disapproval and in the
Diplomacy and Trade (Left) tree, there are institutions that you
can design that, when built in your system, will increase their
happiness.  Additionally, certain factions are inherently
happier or more discontent. If you run into this problem a lot,
consider trying new factions! Take special note of the [faction]
affinity, found by hovering over the faction name in the new
game screen or the diplomacy panel. These can vary from how the
UE and Sheredyn get manufacturing bonuses for tax rates from
about 30-100% to how the Hissho get a huge FIDS bonus for
successfully invading
