The Grand Cross of the Iron Cross (Großkreuz des Eisernen Kreuzes) was the highest level of the Iron Cross decoration during World War II. However, it should be noted that there was no specific design or variant of the Grand Cross of the Iron Cross established in 1939.
The Iron Cross itself is a famous German military decoration, originally established in 1813 by King Friedrich Wilhelm III of Prussia. During World War II, the Iron Cross underwent some changes in design and the criteria for awarding it were expanded. The Grand Cross was the highest grade of the Iron Cross and was typically awarded for exceptional leadership and outstanding military achievements.
The Grand Cross of the Iron Cross consisted of a black Maltese cross with white enamel borders. In the center of the cross, there was a silver Prussian crown, surrounded by a silver oak wreath. The reverse side of the cross was plain and unadorned. The Grand Cross was worn suspended from a wide red ribbon with white-black-white edge stripes.
It's important to note that the Grand Cross of the Iron Cross was a rare and prestigious award, and only a limited number were awarded during World War II. The exact number of recipients and the specific circumstances varied, as it was primarily awarded by Adolf Hitler and was a personal decoration reflecting his choice.
