Croatian checkerboard
It first came into use in Croatian coat of arms around year 1495, as depicted on a temple hall located in Innsbruck, Austria. There is likelyhood that it has been borrowed by the House of Habsburg (who ruled the Hungarian-Croatian throne at the time) from other West Slavic coats of arms, as the silver-red colored pattern was popular among the 12–14th century Polish and Czech noble families. The cheque pattern in European heraldry was likely inspired by the board game of chess.
