There is strength in union. This expression is derived from numerous similar ones pronounced by leaders in ancient Greece, Rome, and other states. The Romans said unitate fortior, a translation from the Greek of Periander, the tyrant of Corinth (ca. 627–586 b.c.). American patriots revived the completion of the phrase, divided we fall, which became a kind of national slogan in the nineteenth century. However, it also was applied to entities smaller than a nation. “The prosperity of the House of Rothschild is due to the unity . . . of its members . . . a fresh example of the saying that ‘union is strength’” (Edward Walford, Tales of Great Families, 1877). Today the cliché is often used in a semijocular fashion, as, for example, by a doubles team in tennis.
