How did the igbo society fall apart?

-Christianity: The church disproved many of the Igbo superstitions, and implicitly encouraged the Igbo to break traditions.
-Settlers: The settlers killed the village of Abame, and attempted to convert the rest, while imposing their power upon the lands.
-The Ibo tribe: Their lack of a central structure made them easy to separate and convert or conquer. They could not offer a consolidated defense against the invaders and their customs. Their own culture was occasionally repressive, and caused rifts between the people and the society.
-Their own culture: Their own culture prevented them from stopping their brothers who had joined the white man's ranks.
-Soldiers: The soldiers prevented the Ibo from forcefully removing the white men.
-The converts: The converts would bring white reinforcements in event of any revolution.
