Several explorers from across Europe explored the lands that became Nebraska. In 1682, René-Robert Cavelier, Sieur de La Salle claimed the area first when he named all the territory drained by the Mississippi Riverand its tributaries for France, naming it Louisiana .

In 1714, Etienne de Bourgmont traveled from the mouth of
the Missouri River in Missouri to the mouth of the Platte River, which he
called the Nebraskier River, becoming the first person to approximate the
state's name. With the goal of reaching Sante Fe by water, the pair of French-Canadian
explorers named Pierre and Paul Mallet reached the mouth of what they named
the Platte River in 1739. They ended up following the south fork of the
Platte into Colorado.
In 1762, by the Treaty of Fontainebleau after France's defeat by Great Britain in the Seven Years' War, France ceded its lands west of the Mississippi River to Spain, causing the future Nebraska to fall under the rule of New Spain, based in Mexico and the Southwest. In 1795 Jacques D'Eglise traveled the Missouri River Valley on behalf of the Spanish crown. Searching for the elusive Northwest Passage, D'Eglise did not go any further than central North Dakota.
In 1803 the United States purchased the Louisiana
Territory from France for $15,000,000. What became
Nebraska was under the "rule" of the United States for the first
time. In 1812 President James Madison signed a bill
creating the Missouri Territory, including the present-day state of Nebraska.
Manuel Lisa, a Spanish fur trader from New Orleans, built a trading post
called Fort Lisa in the Ponca Hills in 1812. His effort befriending local
tribes is credited with thwarting British influence in the area during the War
In 1854 the Nebraska Territory was created by the Kansas–Nebraska
Act. It was an organized incorporated territory of the United States that
existed from 30 May
1854, until 1 March 1867, when the final extent of the territory was admitted
to the Union as the State of Nebraska.
A constitution for Nebraska was drawn up in 1866. There was some controversy over Nebraska's admission as a state, in view of a provision in the 1866 constitution restricting suffrage to White voters; eventually, on February 8, 1867, the United States Congress voted to admit Nebraska as a state provided that suffrage was not denied to non-white voters. The bill admitting Nebraska as a state was vetoed by President Andrew Johnson, but the veto was overridden by a supermajority in both Houses of Congress. Nebraska became the first–and to this day the only–state to be admitted to the Union by means of a veto override.
The territorial seal of Nebraska was never adopted by any act of the legislature; but as it existed in fact, was two and one-half inches in diameter, and bore the following devices: ‘ n the centre a chart, inscribed “ The Constitution,” supportted on the right hand by a man in citizen’s dress, and on the left hand by a man in a hunting frock; holding a gun resting on his left arm, - both of these supporters pointing to an American ensign waving over the chart. On the right of the citizen a locomotive, plow, and other agricultural emblems. On the left of the hunter a river, steamboat, and sheaf of wheat. The sun’s raya are seen behind the folds of the American flag. Over these devices the motto, “ Popular Sovereignty,” under them, the word “ Progress.”

In 1925 this seal came, in yellow lining, in the middle of the blue cloth of the State flag.
Nowadays the seal is often represented in full color.

Nebraska, 1876 
A state emblem was
introduced in 1876. It is derived from the seal of 1867 and consequently
shows the picure of that seal in full color, placed on a shield, with the
motto EQUALITY BEFORE THE LAW on a ribbon underneath.  These coats of
arms were never officially adopted or accepted.

When a State flag was
designed in 1925, the opportunity was taken to redesign the seal which would
be placed in the centre of the flag.. A new state seal was designed indeed
by Bertram Goodhue, the architect of the Nebraska State Capitol. His design
was thoroughly of a heraldic nature and can be characterized as a classical heraldic
achievement, showing a central piece with a crest and supporters.
“ When the legislature met in January 1925, Mrs. Florence Hazen Miller of Crete, a staunch advocate of a Nebraska flag, prevailed upon Rep. J. Lloyd McMaster of Lincoln to introduce HR 67, a bill to create an official state banner. The bill specified that the banner would be national blue with the seal of Nebraska in the center. It said nothing about the redesigned Goodhue seal, so if it were to pass, the original and still official state seal would appear on the banner.” In this way the Goodhue achievement died a silent death and the opportunity to introduce a State achievement passed by.

Distinctive Unit Insignia
A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a gold ellipse, long axis horizontal, charged with a blue horizontal stripe at the top above two gold five-bastioned forts one on the left and right of a vertical light green cornstalk issuing from base, lower leaves extending in back of the forts, and at the top of the stalk a full gold ear of corn partially husked projecting over the stripe and above the top of the ellipse.
The partially husked ear of corn alludes to the crest used for the Nebraska Army National Guard and indicates the organization's allocation; together with the cornstalk it also refers to the official nickname "Cornhusker State." The blue horizontal stripe signifies "flat water," the meaning of the Indian name for the Platte River "Nebrathka." The ellipse refers to Lincoln, the Capital City and location of the State Headquarters of the Army National Guard, which is situated in a shallow elliptical area. The forts symbolize the State of Nebraska, and the vital role of the militia's contribution in the settlement of the West.
The distinctive unit insignia was originally approved for Headquarters and Headquarters Detachment and noncolor bearing units of the Nebraska Army National Guard on 9 July 1971. The insignia was redesignated effective 30 December 1983, for Headquarters, State Area Command, Nebraska Army National Guard.
