English: White-red-blue historical flag of Moravia. One of the forms of the Moravian flag based on the colours of the Moravian eagle in the form of a white-red-blue tricolour (Moravian colours). It was used by the Slavic (Czech)-speaking Moravians probably exceptionally in 1848, also in the second half of the 19th century and at the beginning of the 20th century, when the red-white bicolour and the red-white-blue tricolour were much more widely used flags, especially by the Slavic-speaking population.

Other tricolours and bicolours used (in terms of the order of colours recorded in the sources) 1) derived from the colours of the Moravian eagle: red-white-blue, red-blue-white, red-white, white-red a 2) derived from the colours of a red and gold chequered eagle with a golden crown and armour and a red tongue in a blue field of the shield (considered during the 19th century and at the beginning of the 20th century (until 1918) by the provincial authorities as the Moravian eagle - the coat of arms of the country of Moravia, with reference to the coat of arms of Frederick III. issued for the Moravian estates from 1462, which became widely known in the 1830s, and then in 1848, when it was used as the initial evidence for the claim of gold and red as the correct colours for the check of the eagle in the provincial coat of arms (and hence yellow and red as the provincial colours, respectively). the colours of the provincial flag in the form of bicolour), as opposed to the "older" silver and red (and hence red and white as the provincial colours, respectively the colours of the provincial flag in the form of bicolour, attested for the first half of the 19th century), and for this reason promoted by them from above): yellow-red and red-yellow.

The Moravian Margraviate, the country of Moravia and the country of Moravia-Silesia did not adopt a flag in the 19th or 20th century, nor did they establish their flag as a legal entity by any legal act. It was based on various historical documents, drawings and descriptions, the use of which had no legal basis. The Moravian flag only acquired this status in 2002-2003 with the awarding of coat of arms and flags to the current regions, half a century after the abolition of the provincial system and the introduction of the regional system. The flag is codified in the upper field of the flags of the regions Vysočina, Jihomoravský, Olomoucký and Zlínský and also in the upper field of the flags of the regions Pardubický a Moravskoslezský.
