The Holy Roman Empire (10th century – 1806, known as the Holy Roman Empire of the German Nation after 1512) did not have a national flag, but black and gold were used as colours of the Holy Roman Emperor and featured in the imperial banner: a black eagle on a golden background. After the late 13th or early 14th century, the claws and beak of the eagle were coloured red. From the early 15th century, a double-headed eagle was used.
