Explanation:
I'm just quoting from a website
"the factors leading to the downfall of empires of Ghana, Mali, and Songhai
Climate change and struggles with Berber groups in the Sahara led to the downfall of the Ghanaian Kingdom
Later kings followed the patrilineal tradition, where the eldest son succeeds the father. Since there seems to have been no strict tradition, there were many fights over succession. This led to civil wars and was a large part of the reason why the Mali Empire declined.
Like the Mali Empire, the Songhai Empire also suffered from many battles over succession. In Songhai, the brothers of the king often tried to depose him; in turn, some kings tried to protect themselves by killing all their brothers. The last great battle for succession occurred when a great army general challenged a new king. Many men were killed in the battle for control of the country and the Songhai army was weakened. When troops from Morocco invaded to seize control of and revive the trans-Saharan trade in gold, the Songhai Empire could not win and was conquered, making this the last of the great West African empires."
Answer:
Domino Theory
Explanation:
The Domino Theory referred to the idea that if a country became communist, neighboring countries would become communist too, in a more or less short time frame.
The name from the theory comes from the fact that when dominoes are arranged vertically, if one domino falls down, all the other fall down as well.
The Domino Theory was one of the basis for the Vietnam War. The American leadership believed that if Vietnam became communist, neighboring countries such as Laos, Thailand or Malasya would soon become communist too.
In the end, the Domino Theory did not prove fully correct. For example, while Laos did become communist soon after, niether Thailand nor Malasya became so.
