The red-white-blue tricolour has been used as the Croatian flag since 1848, and the pan-Slavic colours are widely associated with romantic nationalism.
While the Banovina of Croatia existed within the Kingdom of Yugoslavia, it had a similar flag without the modern crown above the chequy. After the Kingdom of Yugoslavia was invaded and Croatia became the Independent State of Croatia, the crown was removed and a "U" was placed at the top left of the flag. Also, the first field of the Croatian chequy was white. After Nazi Germany collapsed and the SFR Yugoslavia was created, Croatia's flag had a five-pointed red star with a yellow border in place of the coat of arms. The star was replaced by the coat of arms in May 1990, shortly after the first multiparty elections. The current flag and the coat of arms were officially adopted on 21 December 1990, about six (de facto) or ten (de jure) months before the proclamation of independence from Yugoslavia and a day before the Constitution of Croatia on 22 December 1990.[citation needed]
