What is a simple summary of WW1?

World War 1, also known as the great war, began in 1914 and ended in 1918. It first began after the assassination of Archduke Franz Ferndinand, the presumptive heir to the Austirian-Hungary throne. The Bosnian serbs killed Ferndinand hoping to separate south-Slav provinces to reunite into Yugoslavia. This eventually led to retaliation when they entered land but intruding into foreign land spread fear of dominance of other countries eventually leading to war. The two main groups in the war consisted of the Allies and Central Powers. This war only lasted long because of the advanced industrialization of militarily weapons and transportation as well as the inability to stop the war.
