The Schlieffen plan was a German military plan developed by General Schlieffen. It essentially called for a two-front war with France and Russia during World War I. The point of the plan was for Germany to have a small army fight Russia while the majority would be fighting France in the west. After the defeat of the French, Germany would be able to proceed to Russia. Unfortunately, it was the Schlieffen plan that caused Britain to join the war with the Allies. In order for Germany to get to France, it would have to invade neutral Belgium. In doing so, Britain declared war on Germany for violating Belgian neutrality. This plan also led to the long-lasting stalemate in Paris.
