What is the origin of the eagle, globe and anchor?
Always referred to as the Marine Corps emblem and never as the "EGA," the Marine Corps emblem on the battle color dates from 1868. It was contributed to the Corps by Brigadier General Jacob Zeilin, 7th Commandant. Until 1840, Marines wore various devices mainly based upon the spread eagle or fouled anchor.
In 1868, Gen Zeilin felt that a more distinctive emblem was needed. His choice fell on the device borrowed from the British Marines: the globe. The globe had been conferred on the Royal Marines in 1827 by King George IV. Because it was impossible to recite all the achievements of the Marines on the Corps color, said the King, "the great globe itself" was to be their emblem, for Marines had won honor everywhere.
Gen Zeilin's U.S. Marine globe displayed the Western Hemisphere, since the "Royals" had the Eastern Hemisphere on theirs. The eagle, which is a Golden Eagle, and fouled anchor, which means the anchor has a cable attached on the emblem, were added to leave no doubt that the Corps was both American and maritime.
Scarlet and gold are the official colors of the Marine Corps per Marine Corps Order No. 4, April 18, 1925. The colors, however, were not reflected in the official Marine Corps standard until Jan. 18, 1939. All guidons, banners, athletic ribbons, pennants and other articles ordinarily designed to represent the Marine Corps will use these colors.
