The main cause of WWII is the same as that in the first world war, which was mainly allegiances; the Nazi party of Germany invaded Poland, which brought Britain into the war, and then continued to expand across Europe. The primary nations in the allied forces were: Great Britain, France, Poland, USA, Norway, Canada, the USSR, and Denmark, and the primary nations in the Axis Powers were: Germany, Italy, Romania, Bulgaria, and Japan. The main effect of the WWII was the Cold War, a period of about 50 years where the USA and USSR were making threats about nuclear war, as well as the destruction of most of Europe. Another effect was the prevention of Germany to control a Navy. The war ended on September 2nd, 1945, with the surrender of Japan and Germany earlier that year.
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."
As far as I now, Marcus Perpena (the consul of 92 BC) was said to have lived to 98. I found this on a website called Quora. (not trying to advertise)
Hope this helped!
"<span>d. He attempted to change Greek art, so that it would exemplify the violence and emotions surrounding the defeat of the Persians" is not true regarding Pericles, since there was no such "control" of art in general. </span>
