Historian [[Akamine Mamoru]] identifies the "Gusuku Period" of Okinawan history as beginning with the advent of agriculture, and ending with King [[Sho Shin|Shô Shin's]] summoning all the local lords (''[[anji]]'') to reside in [[Shuri]], consolidating his power over all their lands.<ref>Akamine Mamoru, Lina Terrell (trans.), Robert Huey (ed.), ''The Ryukyu Kingdom: Cornerstone of East Asia'', University of Hawaii Press (2017), 12.</ref>

The [[Gusuku period]] of Okinawan history takes its name from these fortresses, which were at their peak at that time.
