"A. The English king made claims to the French throne" is a reasonable answer but it should be noted that the origin of this war is very complex and many people are still guessing.
I think it was to use immagrents to do the work.
1. The Wilmot Proviso is a proposed law by United States politician David Wilmot to ban slavery in western territories gained from Mexico in Mexican-American War.
2. The main issues that led to Henry Clay's proposed compromise were a. California applying for its statehood, b. fugitive slave law was created, and c. northerners wanted the slave trade to be banned in Washington DC.
3. The status of new western territories would be decided by popular sovereignty in which the citizens would be the one to decide (by means of voting) whether their territory would permit or ban slavery.
4. If southern states seceded from the Union, then the southern states would form their own government.

Due to imperialism and nationalism the tension within the countries got greater and greater. Nations were competing with each other for power and started reinforcing their armies which was quite expensive. People started getting rather unhappy and poor.
Each nation had their own problems further more
1. Russia was tired of waging endless wars, the people were starving and the idea of communism seemed very promising
2.The Austro-Hungarian empire was very large and included provinces that spoke other languages and felt the need to be part of an other country
3.Italy was a new nation which had to catch up with other countries...(it managed to build a quite impressive navy though)
4.France had Napoleon in the last century...that was a rather unpleasant turn of events, especially for those who had believed in theideals of the French revolution
