World War One?

Question

What was the alliances and the political system that led to this "great war"?

Answer 1

There were still absolute monarchies in 1914 Europe.
Franz Joseph had been on the throne of Austria/Hungary for over 65 years. Kaiser Wilhelm in Germany and Czar Nicholas were also absolute or near absolute rulers. That meant that a war could be started simply by three men. Very dangerous. Kaiser Wilhelm was not a diplomatic man, Czar Nicholas was not a very intelligent man, and Emperor Franz Joseph was an old man left over from a previous century.
Franz Joseph's nephew and heir to the throne of Austria and Hungary was assassinated in Sarajevo by a Serb, so Austria declared war on Serbia. Russia was allied with Serbia, so the Czar ordered his army to mobilize. That forced Germany to attack France. Why? Because Germany was allied with Austria and the longstanding prepared German plan was to beat France in six weeks - like they did in 1870 - and then send the army by train to the east to beat the Russians who would take more time to move their army.
To get at France, Germany invaded Belgium. Britain was allied to Belgium and had promised to fight if Belgium were attacked. Suddenly you had a world war that might have been only a confined war between Austria and Serbia if the alliances had not cause all of Europe to become involved like a falling set of dominoes. Stupid to the nth degree!

Answer 2

it all starts with potatoes, countries in europe were lack of foods to eat, that's why they thought to invade some other lands, but now we have what is called "french fries" anywhere and the english "internet" and so people became satisfied now.
