The Coalition or Kongeda, was an alliance of twelve Grounder clans and the Sky People who reside in the Eastern United States. The twelve clans were brought together by Commander Lexa to fight against Mount Weather. Since the Grounders don’t use last names, their clan name is used instead. Every clan has a leader and each village within a clan has a leader. All twelve clans follow the Commander. The clans choose their leaders differently, but most are chosen after the old leader has died. Village leaders earn his or her place at the top through acts of strength and ferocity (as in the case of Indra, the Chief of Tondc) and through mentor-ship from previous leaders. The Commander is chosen through a Conclave. At the end of Season Four, the remaining eleven clans (all of Floukru died) and the Sky People unite together into a single clan, entitled “Wonkru”, led by Octavia Blake. They survive the Second Nuclear Apocalypse together within the Second Dawn Bunker.
