Essential Question	Big Ideas
Unit 1 — The Global Tapestry (c. 1200–1450)
How did states form and maintain power?	States developed in response to local environmental, cultural, and economic conditions Rulers used bureaucracy, military power, religion, and tradition to legitimize authority Political unity often coexisted with fragmentation (e.g., Abbasids)
