The Union Jack also appeared on both the 1910–1928 and 1928–1994 flags of South Africa. The 1910–1928 flag was a Red Ensign with the Union coat of arms in the fly. The 1928–1994 flag, based on the Prinsenvlag and commonly known as the "oranje-blanje-blou" (orange-white-blue), contained the Union Jack as part of a central motif at par with the flags of the two Boer republics of the Orange Free State and Transvaal. To keep any one of the three flags from having precedence, the Union Jack is spread horizontally from the Orange Free State flag towards the hoist; closest to the hoist, it is in the superior position but since it is reversed it does not precede the other flags.
