Germany had an alliance system with Austria-Hungary. -Then, on 8/3/1914, Germany declared war on France. They knew France would aid Russia due the alliance system they had together. -Also on 8/3/1914, Germany invaded Belgium. Britain declared war on Germany and Austria- Hungary. World War I had begun.

In September of 1914, the Allies halted Germany at the Marne River and each side dug trenches. No man s land was the area between the trenches. -At the Battle of the Somme, on July 1, 1916, Britain lost 60,000 troops in a single day. Over one million died in the end. This grew into 3 years of trench warfare.

Socialists blamed capitalistic imperialism for starting the war and did not want to intervene. -America was also a Melting Pot of many people groups. European immigrants did not want to fight their own people groups. However, Germany s aggressive offensive created sympathy for the Allies.

Over 700,000 Germans reached the point of starvation. -Germany began fighting the blockade by using submarines called U-boats. -On May 7, 1915, the Lusitania, a British Luxury Liner, was sunk and destroyed. Over 1,000 people died and 128 were American. America was furious with Germany over the incident.
