Flag of PrussiaThe state of Prussia had its origins in the separate lands of the Margraviate of Brandenburg and of the Duchy of Prussia. The Margraviate of Brandenburg developed from the medieval Northern March of the Holy Roman Empire, passing to the House of Hohenzollern in 1415. The Duchy of Prussia originated in 1525 when Albert of Brandenburg-Ansbach, a member of a cadet branch of the Hohenzollern house, secularized the eastern lands of the Teutonic Knights as a Polish fief.
Flag of GermanyThe national flag of Germany is a tricolour consisting of three equal horizontal bands displaying the national colours of Germany: black, red, and gold (Schwarz-Rot-Gold). The flag was first sighted in 1848 in the German Confederation. It was officially adopted as the national flag of the German Reich (during the period of the Weimar Republic) from 1919 to 1933, and has been in use since its reintroduction in Federal Republic of Germany in 1949. Since the mid-19th century, Germany has two competing traditions of national colours, black-red-gold and black-white-red.
Iron CrossThe Iron Cross (Eisernes Kreuz, , abbreviated EK) was a military decoration in the Kingdom of Prussia, and later in the German Empire (1871–1918) and Nazi Germany (1933–1945). The design, a black cross pattée with a white or silver outline, was derived from the insignia of the medieval Teutonic Order and borne by its knights from the 13th century. As well as being a military medal, it has also been used as an emblem by the Prussian Army, the Imperial German Army, and the Reichswehr of the German Republic, while the Balkenkreuz (bar cross) variant was used by the Wehrmacht.
SwastikaThe swastika (卐 or 卍) is an ancient religious and cultural symbol, predominantly in various Eurasian, as well as some African and American cultures, now also widely recognized for its appropriation by the Nazi Party and by neo-Nazis. It continues to be used as a symbol of divinity and spirituality in Indian religions, including Hinduism, Buddhism, and Jainism. It generally takes the form of a cross, the arms of which are of equal length and perpendicular to the adjacent arms, each bent midway at a right angle.
KriegsmarineThe Kriegsmarine (ˈkʁiːksmaˌʁiːnə, War Navy) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the Kriegsmarine grew rapidly during German naval rearmament in the 1930s.
