The colors of the Lords of Schwarzburg should really be gold and blue, derived from the house crest. It shows a golden lion on a blue background. The line of the counts of Schwarzburg was divided in 1599 into two lines: Schwarzburg- Rudolstadt and Schwarzburg- Arnstadt (later Sondershausen). The colours blue and white came first into beeing in both Schwarzenburg principalities between 1814 and 1820, shortly after the Napoleonic era, in which National and State flags became popular. For Schwarzburg-Rudolstadt are sometimes showed white and blue as colours of the country, especially for the first half of the 19th century. This color sequence, has never existed for the flags. There were only some plans in Schwarzburg-Sondershausen in 1845 and 1866, to introduce as colors the above-mentioned colours of gold and blue as colours of the country, but these plans were dropped after consultations with Schwarzburg-Rudolstadt. Not so the cockades, the cap badges of the soldiers and officers. In 1867 were the previously uniform blue and white cockades replaced by cockades in different colour sequences: For Schwarzburg-Sondershausen were introduced white-blue-white cockades and for Schwarzburg-Rudolstadt cockades in blue-white-blue. The flag of the Prince of Schwarzburg-Rudolstadt shows, in principle, apart from a few details, the same appearance as the coat of arms of the Principality. The colours of the small Thuringian States persisted after the abdication of the princes, even after the formation of the State of Thuringia on 5th of January in 1920, but they became territorial flags. On 25th of April in 1922 was adopted the "Regulation on the flagging of state buildings", which laid down, that the previous territorial flags have to be no longer in use. Just the abolition of the territories on 1st of April in 1923, was the end for the colours of the former Thuringian States.
The coat of arms of the Lords of Schwarzburg shows a golden lion with a red arms on a blue background. The coats of arms of both principalities differ only slightly, but some details of this heraldry are disputed. The lesser coat of arms of the Principality of Schwarzburg-Rudolstadt shows a golden shield and on it the black double-headed imperial eagle with red arms, holding a blue orb and a scepter and bears a breastshield which shows a princely crown. Above the eagle is to see the crown of the House of Habsburg with red fittings. In the narrow foot of the coat of arms are placed red marks of dignity (fork and comb) on silver. The blazon is adorned with a princely crown.
