The esperanto flag has a green background with a white square in the upper lefthand corner, which in turn contains a green star. Esperantists use the flag for representing their language and culture. Swedish esperantist G. Jonson has iniciated use of the green color and the green star. C. Rjabinis and P. Deullin has created final suggestion of the flag in 1893. The green color represents hope and the white color represents peace. In Esperanto they call it "Esperanto-flago" (Esperanto flag).
