Coat of arms of Prussia

Henceforth, the Prussian eagle, now royally crowned and with 'FR' (Fridericus Rex, "King Frederick") on its breast, was placed in an escutcheon on the shield with 25 quarters instead of the electoral scepter.

They are also to be found as supporters of the arms of Braunschweig, Königsberg, and the Dutch towns of Anloo, Beilen, Bergen op Zoom, Groede, Havelte, 's-Hertogenbosch, Oosterhesselen, Sleen, Sneek, Vries and Zuidwolde.

In 1708 Frederick announced that he would place the quarters of the dukes of Mecklenburg in the Prussian arms to stress his rights to Mecklenburg-Schwerin and Mecklenburg-Strelitz if their ducal lines were to die out.

Around the shield, with 36 quarters (including Veere-Vlissingen and Breda), appeared the Order of the Black Eagle with a crowned helmet resting on top.

Frederick William II inherited the Franconian cadet branches (Ansbach and Bayreuth) of the House of Hohenzollern in 1791.

The so-called 'middle arms' were then issued: a shield with the same four escutcheons and ten quarters for Silesia, Rhineland, Posen, Saxony, Pomerania, Magdeburg, Jülich-Cleves-Berg, and Westphalia.

On 7 December 1849, the Swabian lines of Hohenzollern-Sigmaringen and Hohenzollern-Hechingen were annexed by Frederick William IV, who had followed his father on 7 July 1840.

The middle arms of 1873 show more clearly the changes by the additions of Schleswig-Holstein, Hanover, and Hesse-Kassel and the removals of Magdeburg and Cleves-Jülich-Berg.

The family coat of arms, first adopted in 1192, began as a simple shield quarterly sable and argent.

A century later, in 1317, Frederick IV, Burgrave of Nuremberg, added the head and shoulders of a hound as a crest.

The new Prussian arms depicted a single black eagle, displayed in a more natural than heraldic style.

While part of Nazi Germany, the free state's arms depicted a single black eagle, more stylized than before but not in a heraldic manner, with a swastika and the phrase Gott mit uns beginning in 1933.

A black eagle on red is present in the arms of Warmian-Masurian Voivodeship in Poland, which corresponds to what was southern East Prussia.
