Mass Eviction is a liberation trophy for freeing 7 Mongol territories in Kamiagata, the snowy northern region you reach in Act 3.
Once Act 3 opens Kamiagata, clear camps and guard posts as you travel. Seven liberations unlock the trophy.
Fit for the Khan has two general camps that count as major territories.
