The today’s flag of Czechia was officially introduced as flag of Czechoslovakia on 30th of March in 1920, and was taken over as flag of Czechia in preparation for the separation of Slovakia on 17th of December in 1992. It shows two horizontal stripes in white and red and on the pole a blue until the middle of the flag reaching isosceles triangle. The colours white and red are the since the 12th century known Bohemian colours (white lion on red), the blue triangle should today represent Moravia but former Slovakia. The colours of the flag are laid down in the "Act of the Czech National Council No. 3/1993 Coll. on the State Symbols of the Czech Republic with effect from 1st of January in 1993", but only as a colour sample imprint in Annex No. 3, without specifying colour values. The given colours are interpreted as follows: Blue = Pantone 293, Red = Pantone 485.
Many Slavic nations create on the 19th century own flags – in context with a growing Slavic nationalism. Thereby played the Panslavism an important roll, a political movement of the 18th/19th century, which would unite all Slavs in one nation. The most Slavic nations however lived in this times under Austrian, Turkish or even German rule. The Panslavism saw in Russia a model, because the Russians were, apart from Montenegro, the only free Slavic nation. In this way the colours of the Russian flag became to an idol of the Panslavists, and in the end to a colour's pattern in the designing of the flags of many Slavic nations. Those flags carried and carry except few exceptions the Russian colours white, blue and red as mutual attribute. From there this colour's combination is named "Panslavic Colours". The three colours had been shown for the first time in the year 1848 on the Slavic Congress in Prague, but in a lengthwise striped tricolour. They represented the Czech and the Slovaks.
The today’s coat of arms was adoped on 17th of December in 1992. It shows a quartered shield, in the first and fourth field the scutcheon of Bohemia (silvery double-tailed lion with golden crown on red ground), in the second field the scutcheon of Moravia (silvery-red chess-board styled eagle with with golden crown on blue ground), and in the third field the scutcheon of Silesia (golden crowned black eagle with a silvery by cloverleafs finished crescent with a small cross in the middle on golden ground).
The Sudetenland – the area of settlement of the Germans – belonged directly to the German Empire, the area of settlement of the Czech was as "Protectorate of Bohemia and Moravia" subordinated unter German supremacy.
