Flag of Croatia.The flag of Croatia is one of the state symbols of Croatia. It consists of three equal size, horizontal stripes in colours red, white and blue. The flag combines the colours of the flags of the Kingdom of Croatia (red and white), the Kingdom of Slavonia (white and blue) and the Kingdom of Dalmatia (red and blue). Those three kingdoms are the historic constituent states of the Croatian Kingdom. In the middle is the coat of arms of Croatia.
