### Long before European contact, Nigeria flourished with world-class empires! 👑 Contrary to colonial myths, Nigeria possessed some of the world's most advanced governance systems, urban planning, and metallurgy! **1. The Kingdom of Benin**: * **The Oba of Benin**: Revered spiritual and political monarch. * **The Benin Moat & Walls**: One of the largest earthworks in human history, longer than the Great Wall of China! * **The Bronze Casters Guild (Igun Eronmwon)**: Master artisans who created intricate royal plaques and Queen Mother Idia masks using the advanced **lost-wax method (cire perdue)**. **2. The Old Oyo Empire**: * A sprawling constitutional empire founded by Oranmiyan. * **Masterpiece of Checks and Balances**: * **The Alaafin**: Executive King who ruled the empire. * **The Oyomesi**: Council of seven principal chiefs led by the **Bashorun** (Prime Minister). * If an Alaafin became tyrannical, the Oyomesi presented him an empty calabash (*Igba Iku*), commanding him to step down! * **The Ogboni Society**: Mediated between the Alaafin and Oyomesi to maintain constitutional peace!
