The election of 1860 is what you would've said was the last straw for the south. For even though Lincoln wasn't put on the ballot anywhere in the south they had more than 1 man running so even though most of the south voted Breckenridge thou but for Virginia, Kentucky, and Missouri and Breckenridge would have won with those four states. So feeling threatened about the newly elected Lincoln right after that south Carolina seceded in December 1860 followed by the 6 others and later to be 11 states. so even though there was many things leading up the CSA the election of 1860 was the straw that broke the camels back and Lincolns becoming president is what caused south Carolina to seceded. Hope this helps and if you have anymore projects let me know cause I find this fun doing civil war projects
That the Article of Confederation was too weak gor the public
The treaty of Versailles was an unfair one. The "war guilt" clause forced Germany and her allies to take all the blame for the world war. Moreover, Germany lost it's land, overseas colonies, population, and coal and iron industry. Germany was also made to pay reparations and limit their armed forces.
The treaty of Versailles was an invitation to deadlier wars in the future. In fact, it can be concluded that the treaty was a controversy in itself. Because Germany was subjected to ill treatment and was made to pay reparations beyond the country's capacity post war, it became the mojor cause for the WW II.
