The order came in four classes: Grand Cross (
Großkreuz), Commander's Cross 1st Class (
Kommandeurkreuz I. Klasse), Commander's Cross 2nd Class (
Kommandeurkreuz II. Klasse) or sometimes just Commander, and Knight's Cross (
Ritterkreuz). Generally, the rank of the recipient determined which grade he would receive - the Grand Cross went to monarchs and the highest field commanders, the Commander 1st Class to senior generals, the Commander 2nd Class to officers major and above (with a few exceptions) and the Knight's Cross to all officers. Again with few exceptions, one was required to have received a lower grade before receiving the next higher grade. During World War I, there were 12 awards of the Grand Cross, 14 awards of the Commander 1st Class, 153 awards of the Commander 2nd Class, and 2,728 awards of the Knight's Cross As an example of the progression,
Rupprecht, Crown Prince of Bavaria, a general and later field marshal, received the Knight's Cross in August 1914, the Commander 2nd Class in June 1915, the Commander 1st Class in January 1917, and the Grand Cross in May 1918. ==Description and wear==
