Children’s Board Game Depicting the Austro-Prussian War of 1866 (1866) This contemporary lithograph brought a sanitized version of the Austro-Prussian War of 1866 into children’s playrooms and family parlors. With throws of the dice the player could move a total of 60 spaces – from preparations for war in the spring of 1866, through the early skirmishes that predated the Battle of Königgrätz on July 3, 1866, to the Prussian victory parade through the Brandenburg Gate on September 21, 1866.
