Leader of the People is an Act 2 story trophy. It unlocks when you finish The Ghost of Yarikawa, holding Yarikawa Stronghold against a Mongol assault and winning over its people.
Complete The Walls of Yarikawa and The Coward of Yarikawa first. Then defend both gates of the stronghold, disable the two siege weapons and beat General Temuge in a duel.
Crouch along the rightmost path to reach the siege weapons without being spotted.
