In 1914, Russia joined World War I. At first, people thought this was a good decision, and the country was united by patriotism. But there were huge problems with supplies, and by 1915 many soldiers were being sent to fight without any guns. Communication was bad, and Army officers argued a lot. That meant that they did not make plans well. The soldiers became unhappy, and over 3,000,000 Russians died. St. Petersburg was also renamed to Petrograd by the tsar in 1914 because he thought St. Petersburg sounds too German, especially for a capital.
