The phrase "Tomorrow, When the War Began" can refer to two distinct things:
- It is the title of a young adult invasion novel by John Marsden, published in 1993. The story is about a group of Australian teenagers who discover their country has been invaded by foreign forces while they were on a camping trip and who then engage in guerrilla warfare to resist the occupation. This novel was adapted into a film in 2010 and a TV mini-series in 2016.
- As a historical phrase referring to the start of a major war, if considering World War I as "the war," it began on July 28, 1914, after Austria-Hungary declared war on Serbia following the assassination of Archduke Franz Ferdinand on June 28, 1914. This conflict later escalated into a global war lasting until November 11, 1918.
Let me know if the question is about the book/film/series or the historical war, and I can provide more specific details.
