Antedating Quote "history is written by the victor" (1919)

[Ken Hirsch]

I've found earlier, almost identical sayings.

  A partir de son nouveau désastre, les chroniques lui attribuent une
  foule de crimes; l'histoire est juste peut-être, mais qu'on ne
  l'oublie pas, elle a été écrite par les vainqueurs.

  Vaincu dont l'histoire fut écrite par les vainqueurs, Robespierre
  avait laissé une mémoire maudite.

  "Vanquished—his history written by the victors—Robespierre has
  left a memory accursed"

  La storia di questi avvenimenti fu scritta dai vincitori, i quali non
  hanno mai una parola di compassione o di lode pei caduti.

  Giovanni Marco Burigozzo bottegaio lombardo fu l' ultimo raccoglitore
  dei dolori del popolo ; appresso venne la storia classica, cortigiana,
  prezzolata: l'istoria scritta dai vincitori.

http://tinyurl.com/y8euemp 1866 this translated into English
  John Mark Burigozzo, a Lombard shopkeeper, was the last annalist who
  recorded the sorrows of the people. Then came classic, courtly and
  salaried historians—history written by the victors. There is need of
  great caution in reading the verdict of a history written with the
  sword.
