Aro vs Nri. They the are two major ancestors of the the great Igbo Nation, there have been an argument on whom among them welds more POWER, this is my little understanding. Aro is the founder of Southern Igboland while Nri is that of Northern. Both did not established kingdoms until 10th Century. Nri Kingdom was established in 10th around 948 Ad while Aro Kingdom was established in 17th Century around 1650 or there about. The kingdom did not operate the same way, Nri was a non military Kingdom which means that the ruler had no military power over the subjects, the government in practice was elective monarchy, meaning that the rulers were elected from the people who are from the monarchical lineage. Aro Kingdom was established after about 700 years of Nri Kingdom, it was a pure military Kingdom with the Warriors from Abiriba, Ohafiah and to an extent, Afikpo. Both Kingdom practiced Odinani religion. The headquarter of Nri Kingdom was Igbo - Ukwu while that of Aro was Arochukwu. Nri Kingdom was abolished by British government after he lost the war to them while Aro was abolish a bit earlier. POWER: Eli, the founder of Nri was a powerful chief priest and so were his first born descendants (up till today). He was charismatic, his fame exceeded Igboland. This continued with his lineage who later got in contact with Bini Kingdom where they were called to offer sacrifices to gods. They were expert of Odinani religion. Eli's power lies on his spiritual duties, he was not known for fighting or as a warrior. However, he was greatly loved and respected. Aro was a no nonsense man, a fighter and warrior, his major power lies on the edge of his swords. However, he performed priestly duties when called to, and so were his first born descendants, up till today. Aro was a typical bully whose descendants played a key role in the ever ugly slave trade in Igboland.
