The formation of the Three Man Alliance is the first step in a process of twelfth-century consolidation among the Minor Clans, leading to (among other things) the combination of the Mantis, Wasp, and Centipede clans into the Great Clan of the Mantis and, later in the century, the creation of the Minor Clan Alliance. It is the creation of the Three Man Alliance and their military victory over the Scorpion Clan that first inspires the Minor Clans to band together for greater benefit and effect, and many successful officers from that first military alliance eventually go on to achieve military and political prestige within the Minor Clan Alliance.
The fighting technique of the Three Man Alliance is formed by the combined efforts of several experienced soldiers from the Sparrow and Wasp. The warriors pool their life experience and develop a unified technique to carry back to their respective clans. Although the Three Man Alliance is superseded during the later Clan War by Yoritomo's Alliance, the technique it developed survives, and decades later it is still occasionally taught in Suzume and Tsuruchi dojo.
