Why were african tribes, colonies, and countries easy to conquer?

These were easily conquered do to A. Them not having the fire power B. They were separate and were over whelmed

A lot of factors went into why it was so easy to conquer the Africa a few of them being
-large language barriers between tribes making it harder to relay information between each other to warn of European
-they didn't necessarily have a central form of government or unity, meaning it was usually each tribe protecting it selfs rather that all working together
-and lastly they lacked in weapons that could match the Europeans in power, (most parts of Africa didn't use metal weapons) evidently making it easier for them to lose fights
