Hello,
There are 6 years that have a lot of main dates but, I will help you create a timeline to sum up 10 important ones within those 6 years.
Explanation:
--In 1914--
July 28 - Austria-Hungary declares war on Serbia. Russia begins mobilizing its troops. (Start date of the war)
August 23 to 30 - The Battle of Tannenberg is fought between Germany and Russia. The Germans defeat the Russian Second Army. (Germany had wanted war with the Russians and French)
October 19 to November 22 - The Allies defeat the Germans at the First Battle of Ypres.
--In 1915--
February 4 - The Germans begin to use submarines against Allied merchant ships around the island of Britain. (The Germans had submarines which was a bit advanced to other countries so they used it as an advantage during the war)
May 7 - The Lusitania, a luxury British passenger ship, is sunk by a German submarine. 1,195 civilians were killed. This act sparks international outrage and contributes to the United States joining the war against Germany. (Germans had caused a lot of problems when they killed the thousands of lives causing the American people to team up against the Germans)
