I've already got my hands full, but next year is the 100 year aniversary of the begining of World War 1.
Hint Hint
Here is a time line of the begining.
1914
•June 28 - Archduke Franz Ferdinand, heir to Austria-Hungary's throne, and his wife, Sophie, are assassinated by Serbian nationalist Gavrilo Princip while the couple were visiting Sarajevo.
•July 28 - Austria-Hungary declares war on Serbia.
•August 1 - Germany declares war on Russia.
