When William Came: A Story of London Under the Hohenzollerns is a novel written by British author Saki (the pseudonym of Hector Hugh Munro) and published in 1913. It is set several years in what was then the future, after a war between Germany and Great Britain from which Germany emerged victorious. The "William" of the book's title is Kaiser Wilhelm II, who came from the House of Hohenzollern, hence the subtitle. The book chronicles life in London under German occupation and the changes that come with a foreign army's invasion and triumph. The novel predicts the Great War (in which Saki would be killed) and is an example of invasion literature, a literary genre which flourished at the beginning of the 20th century as tensions between the European great powers increased.
