This agreement marked the emergence of Russia and Germany from the diplomatic isolation caused by World War I (1914-1918).
During World War II numerous partisans from Rapallo were shot by German occupation troops.
Rapallo has been known for its climate that made it over the years the winter residence of preference for most of the affluent Italians living in the North West of Italy. Its proximity to the coast makes for mild winters where people can enjoy easy strolls on the sunny promenade and the golfers can enjoy one of the oldest courses in Italy, opened in 1930.
Friedrich Nietzsche wrote that the ideas for Zarathustra first came to him while walking on two roads surrounding Rapallo, according to Elisabeth Förster-Nietzsche in the introduction of Thomas Common's translation of Thus Spake Zarathustra. The writer Ezra Pound spent much of the late 1920s and 1930s living in the town. The author, caricaturist and parodist Max Beerbohm lived in Rapallo from 1910 until his death in 1956, returning to Britain during World War I and World War II. The influential theatre designer and artist Gordon Craig lived in the Villa Raggio, next door to Beerbohm, from 1917 to 1928
