France, Émile Driant writing as Capitaine Danrit, wrote of future wars opposing France to Great Britain (La Guerre Fatale) or to Germany (La Guerre de Demain). In Asia Invasion literature had its impact also in Japan, at the time undergoing a fast process of modernization. Shunrō Oshikawa, a pioneer of Japanese science fiction and adventure stories (genres unknown in Japan until a few years earlier), published around the start of the 20th century the best-seller Kaitō Bōken Kidan: Kaitei Gunkan ("Undersea Battleship"): the story of an armoured, ram-armed submarine involved in a future history of war between Japan and Russia.

In the US One of the earliest invasion stories to appear in print in the US was "The Stricken Nation" by Henry Grattan Donnelly published in 1890 in New York. It tells of a successful invasion of the US by the UK. The move of U.S. public opinion towards participation in World War I was reflected in Uncle Sam's Boys at The Invasion of the United States by H. Irving Hancock. This four-book series, published by the Henry Altemus Company in 1916, depicts a German invasion of the US in 1920 and 1921. The plot seems to transfer the main story line of
