How did the alliances in place before ww1 affect the war

The Alliance system was one of the causes of World War I. Prior to the war there were two alliances. One was the Triple Alliance. This included Austria Hungary, Germany, and Italy. The other alliance was the Triple Entente. This included Soviet Union Russia, Great Britain, and France. The danger of these alliances. hope u have a wonderful day :)

The alliances before WWI were known as "tangled alliances" because they intermingled so often and whenever one country went to war, they brought along with them all of their allies. It started a chain reaction. This made WWI a much larger conflict than it would have originally been.
