The Nazi Party used the traditional German eagle, standing atop of a swastika inside a wreath of oak leaves. It is also known as the "Iron Eagle". When the eagle is looking to its left shoulder, it symbolises the Nazi Party and was called the Parteiadler. In contrast, when the eagle is looking to its right shoulder, it symbolises the country (Reich) and was therefore called the Reichsadler. After the Nazi Party came to national power in Germany, they replaced the traditional version of the German eagle with the modified party symbol throughout the country and all its institutions.
