Modern LionClan was formed to face the threat of BloodClan and Modern TigerClan wanting to take over the forest. Originally, LionClan consisted of ThunderClan and WindClan, who allied against the threat of TigerClan. When BloodClan entered the forest and Scourge killed Tigerstar, he gave the Clans three days to decide to leave or fight. Firestar convinced the other Clans to resist and join LionClan. LionClan won the battle and was disolved soon after.
