New Jersey was the 3rd state in the USA; it became a state on December 18, 1787. - State Capital is Trenton. - Nickname is Garden State. - New Jersey's official state flag was adopted on March 26, 1896. The flag has a buff (light yellow-brown) background; this is the color of part of the uniform selected by General George Washington in 1779 for his New Jersey Continental Line. Part of the state seal (which was designed by Pierre Eugene de Simitiere in 1777) is in the center. In the center is a blue shield with three plows in it. On the sides of the shield are the goddess of liberty (holding a staff and the cap of freedom) and the goddess of agriculture (holding a cornucopia filled with food). Above this is the head armor of a knight, a horse's head, and blue filigrees. Below are the words "LIBERTY AND PROSPERITY" and the date "1776." The goddesses symbolize liberty and prosperity.
