Context paragraphs:
Great Seal of Ireland: The Great Seal of Ireland was the seal used until 1922 by the Dublin Castle administration to authenticate important state documents in Ireland, in the same manner as the Great Seal of the Realm in England.  The Great Seal of Ireland was used in the Lordship of Ireland (1180s–1534) and the Kingdom of Ireland (1534–1800), and remained in use when the island was part of the United Kingdom of Great Britain and Ireland (1801–1922), just as the Great Seal of Scotland remained in use after the Act of Union 1707.

Seal of Nevada: The Great Seal of the State of Nevada is derived from the Seal of the Territory of Nevada.  As Nevada prepared for statehood in 1864, its Constitutional Convention began to formalize the features of the state's official seel.  Nevada was admitted as a state on October 31, 1864 by proclamation of President Abraham Lincoln.  On February 24, 1866, the motto "Volens et Potens" ("Willing and Able") was replaced by "All for Our Country".  The design of the seal was formalized, and Nevada's mineral resources are featured with a silver miner and his team moving a carload of ore from a mountain in the foreground.  A quartz mill stands before another mountain.  Transportation and communication are symbolized by a train steaming across the background, with telegraph poles spanning the distance.  Agriculture is represented by a sheaf of wheat, a sickle, and a plow in the foreground.  Nevada's natural environment is symbolized by a brilliant sun rising over snow-capped peaks.  The inner circle of the seal carries the motto "All for Our Country", and Nevada's entry into the Union as the 36th state is shown with 36 stars completing the inner ring.  The perimeter of the seal proclaims "The Great Seal of the State of Nevada".  Mark Twain was said to have convinced the designer to make the two trails of smoke blow in opposite directions as a prank, which was later rectified when the mistake was realized.

Opus Dei (album): Opus Dei is the third studio album by Laibach, released in 1987.  It features "Geburt einer Nation" ("birth of a nation"), a German cover of Queen's "One Vision", and two reworkings of the Austrian band Opus' sole hit single "Live Is Life".  The Opus song became the German language "Leben heißt Leben" and the English language "Opus Dei".  "The Great Seal" is the national anthem of the NSK State, the lyrics taken from Churchill's speech We shall fight on the beaches.  A new arrangement of the song appears on Laibach's album "Volk", with the title "NSK".  On "Volk", the song is credited to Laibach and Slavko Avsenik, Jr.

Seal of Missouri: The Great Seal of the State of Missouri was adopted on January 11, 1822.  Judge Robert William Wells designed the seal.  The center of the seal contains the Great Seal of the United States on the right side, and, on the left, symbols representing the state.  On both sides of the center circle, a bear represents strength and bravery; a crescent moon represents the newness of statehood and the potential for growth.  Surrounding these symbols is the motto "United we stand, divided we fall".  The belt buckle signifies the State's ability to secede from the Union if deemed necessary, i.e., the belt can be unbuckled.  Two mighty grizzly bears support this center shield.  A scroll carries the state motto, "Salus Populi Suprema Lex Esto", a Latin phrase meaning "Let the welfare of the people be the supreme law."  The year 1820 is inscribed in Roman numerals below the scroll, although Missouri was not officially granted statehood until 1821.  A star representing each of the other states of the Union (Missouri became the 24th) graces the top portion of the seal.  The outer circle of the seal bears the words "The Great Seal of the State of Missouri".  Above the shield is a helmet representing Missouri's state sovereignty.  The large star above the helmet surrounded by 23 smaller stars represents Missouri's status as the 24th state.  The cloud around the stars indicates the problems Missouri had in becoming a state.

List of historical national anthems: The oldest national anthem, defined as "a song, as of praise, devotion, or patriotism", is the Dutch national anthem "Het Wilhelmus", which was written between 1568 and 1572, but not then given any official status.  The first anthem to be officially proclaimed as such was "God Save The Queen", adopted by Great Britain in 1745.  "Het Wilhelmus" was declared the national anthem of the Netherlands in 1932; both of these anthems remain in use today.  A royal or imperial anthem is a song that is similar in patriotic character to a national anthem, but which specifically praises a monarch, or royal dynasty.  Some states have doubled their royal or imperial anthem as their national anthem.

Anthem Veterans Memorial: The Anthem Veterans Memorial is a monument located in Anthem, Arizona, dedicated to honoring the sacrifice and service made by members of the United States Armed Forces.  The memorial's five white pillars represent the nation's military branches and are ordered in the size of each service.  Each pillar has an elliptical opening that slants downward toward The Great Seal of the United States.  On Veterans Day (November 11) the design allows the sun's rays to spotlight the Great Seal at precisely 11:11 AM.

Seal of Montana: The Great Seal of the State of Montana was adopted in 1865, when Montana was a United States Territory.  When it became a state in 1889, it was decided to use the same seal.  In 1891, proposals were made to make changes or adopt a brand new seal.  None of these proposals passed legislation.  The outer ring of the seal contains the text "The Great Seal of the State of Montana".  The inner circle depicts a landscape of mountains, plains and forests by the Great Falls on the Missouri River.  A plow, a pick and a shovel are depicted on the front, representing the state's industry.  The banner at the bottom of the seal reads the territorial motto of "Oro y Plata", meaning "Gold and Silver" in Spanish.

We shall fight on the beaches: "We shall fight on the beaches" is a common title given to a speech delivered by Winston Churchill to the House of Commons of the Parliament of the United Kingdom on 4 June 1940.  This was the second of three major speeches given around the period of the Battle of France, with the others designated as the "Blood, toil, tears, and sweat" speech of 13 May, and the "This was their finest hour" speech of 18 June.  Events developed dramatically over the five-week period, and although broadly similar in themes, each speech addressed a different military and diplomatic context.

Great Seal of the Realm: The Great Seal of the Realm or Great Seal of the United Kingdom (known prior to the Treaty of Union of 1707 as the Great Seal of England; and from then until the Union of 1801 as the Great Seal of Great Britain and Ireland) is a seal that is used to symbolise the Sovereign's approval of important state documents.

Great Seal of Northern Ireland: The Great Seal of Northern Ireland is the seal used for Northern Ireland.  The great seal is in the possession of the Secretary of State for Northern Ireland.  The Great Seal was created by the Irish Free State (Consequential Provisions) Act 1922 on the creation of Northern Ireland for possession by the Governor of Northern Ireland to "be used for all matters in Northern Ireland for which the Great Seal of Ireland was theretofore used"
