Treaty of Ghent: The Treaty of Ghent (8 Stat.  218 ) was the peace treaty that ended the War of 1812 between the United States of America and the United Kingdom of Great Britain and Ireland.  Both sides signed it on December 24, 1814, in the city of Ghent, Belgium.  The treaty restored relations between the two nations to "status quo ante bellum", restoring the borders of the two countries to the lines before the war started in June 1812.  The Treaty was approved by the UK parliament and signed into law by the Prince Regent (the future King George IV) on December 30, 1814.  It took a month for news of the peace treaty to reach the United States, and in the meantime American forces under Andrew Jackson won the Battle of New Orleans on January 8, 1815.  The Treaty of Ghent was not fully in effect until it was ratified by the U.S. Senate unanimously on February 17, 1815.  It began two centuries of peaceful relations between the U.S. and Britain, although there were a few tense moments such as the Trent Affair.

Italo-Yemeni Treaty: The Italo-Yemeni Treaty of 1926 (also known as the Treaty of San'a) was a treaty between the Kingdom of Italy and Mutawakkilite Kingdom of Yemen.  The treaty was signed in September 1926 and was described as a friendship treaty.  At the time, Italy was ruled by the fascist National Fascist Party with Benito Mussolini as head of government.  The treaty recognized Imam Yahya Muhammad Hamid ed-Din as King of Yemen and acknowledged his claims to Aden.  The treaty was renewed on October 15, 1937, after Italy had annexed Abyssinia (present-day Ethiopia).

Charles I of England: Charles I (19 November 1600 – 30 January 1649 ) was monarch of the three kingdoms of England, Scotland, and Ireland from 27 March 1625 until his execution in 1649.

Treaty of Brussol: The Treaty of Brussol (also known as the Treaty of Bruzolo) was signed on 10 April 1610 in Bruzolo between Charles Emmanuel I, Duke of Savoy, and Henry IV of France, inside the Castle of Bruzolo, (in Susa Valley, near Turin).  Based on the terms of the accord, both signatories agreed to combine their forces in order to remove the Spanish from Italy.  The agreement also dictated that the Duke of Mantua exchange the province of Casale Monferrato for the province of Cremona.  Also, the territories of Montferrat and Milan would be united under the control of Savoy.  Under the treaty, Victor Emmanuel would be restored to the throne of Lombardy.  Also, Henry IV would have his daughter marry Prince Victor Amadeus I and that the King of France, the Republic of Venice, and the Pope guarantee the Duke of Savoy the title of King of Lombardy.  However, this accord was never realized since Henry IV was assassinated by Ravaillac in May 1610.  Marie de' Medici, just crowned queen, fored the treaty.  Even though Henry's death ended the treaty, Charles Emmanuel seized Montferrat from the Spanish in 1613, which led to a war that lasted until 1617.

Peace of Paris (1783): The Peace of Paris of 1783 was the set of treaties which ended the American Revolutionary War.  On 3 September 1783, representatives of King George III of Great Britain signed a treaty in Paris with representatives of the United States of America—commonly known as the Treaty of Paris (1783)—and two treaties at Versailles with representatives of King Louis XVI of France and King Charles III of Spain—commonly known as the Treaties of Versailles (1783).  The previous day, a preliminary treaty had been signed with representatives of the States General of the Dutch Republic, but the final treaty which ended the Fourth Anglo-Dutch War was not signed until 20 May 1784; for convenience, however, it is included in the summaries below.

Treaty of Warsaw (1745): The Treaty of Warsaw was a diplomatic agreement signed in Warsaw on 8 January 1745.  Its birthplace is traced back to Leipzig, Germany.  It was an agreement between Great Britain, Austria, the Dutch Republic and Saxony (the Quadruple Alliance) to uphold the pragmatic sanction enabling their favored candidate Maria Theresa to take the throne of the Austrian Empire.  It also helped the Austro-Saxon alliance secure "the pecuniary support of the maritime powers by the treaty of Warsaw" (Horn, 34).  This brought Saxony into intimate relations with Britain for the first time.  It is considered to be merely the specifying and fixing down of what had been shadowed out as secret modifiers stated in the Union of Warsaw.  The treaty was for reconquering Silesia and “for cutting down that bad neighbor to something like the demensions proper for a Brandenburg Vassal”.  The treaty also aimed to hold together in affairs of the Reich unlike the Frankfurt Union as “30,000 Saxons conjoined to the Austrian force for which the sea powers will furnish subsidy”.  The Treaty was Proposed by the Hungarian and Polish Majestys, Secret Articles, an ulterior Project; however, the sea powers disagreed to this project.  A notionally defensive alliance, it came during the War of the Austrian Succession and within months all the signatories were in an alliance against France.  Along with the sudden death of the Bavarian king, it dramatically changed the balance of power in Germany.  The Allies were ultimately successful in securing recognition for Maria Theresa at the Treaty of Aix-la-Chapelle.  The treaty was secret until Friedrich II discovered it in 1756, and made it known to the world.  The treaty was never absolutely accomplished.

Anglo-Egyptian treaty of 1936: The Anglo-Egyptian Treaty of 1936 (officially, "The Treaty of Alliance Between His Majesty, in Respect of the United Kingdom, and His Majesty, the King of Egypt") was a treaty signed between the United Kingdom and the Kingdom of Egypt.  Under the terms of the treaty, the United Kingdom was required to withdraw all its troops from Egypt, except those necessary to protect the Suez Canal and its surroundings, numbering 10,000 troops plus auxiliary personnel.  Additionally, the United Kingdom would supply and train Egypt's army and assist in its defence in case of war.  The treaty was to last for 20 years; it was negotiated in the Zaafarana palace, signed in London on 26 August 1936 and ratified on 22 December.  It was registered in "League of Nations Treaty Series" on 6 January 1937.

Treaty of Ripon: The Treaty of Ripon was an agreement signed by Charles I, King of England, Scotland, and Ireland, and the Scottish Covenanters on 26 October 1640, in the aftermath of the Second Bishops' War.  The Covenanters were associated with the promotion and development of Presbyterianism as a form of church government, as opposed to Episcopacy, favoured by the crown.

Treaty of Vienna (1738): The Treaty of Vienna or Peace of Vienna was signed on 18 November 1738.  It was one of the last international treaties written in Latin (together with the Treaty of Belgrade signed the following year).  It ended the War of the Polish Succession.  By the terms of the treaty, Stanisław Leszczyński renounced his claim on the Polish throne and recognized Augustus III, Duke of Saxony.  As compensation he received instead the Duchy of Lorraine and Bar, which was to pass to France upon his death.  He died in 1766.  Francis Stephen, who was the Duke of Lorraine, was indemnified with the vacant throne of the Grand Duchy of Tuscany, the last Medici having died in 1737.  France also agreed to the Pragmatic Sanction in the Treaty of Vienna.  In another provision of the treaty, the kingdoms of Naples and Sicily were ceded by Austria to Duke Charles of Parma and Piacenza, the younger son of King Philip V of Spain.  Charles, in turn, had to cede Parma to Austria, and to give up his claims to the throne of Tuscany in favor of Francis Stephen.

Treaty of Copenhagen (1670): The Treaty of Copenhagen or Treaty of 1670 was a treaty of commerce and alliance signed on July 11, 1670, between King Christian V of Denmark and of Norway and King Charles II of England and of Scots.  It was written in Latin.  It was expanded the next day on July 12, 1670, with the Third Article concerning contraband amended and clarified by a declaration in French signed at Copenhagen on July 4, 1780.  The terms of the treaty were later reaffirmed by the Treaty of Kiel, following the defeat of Denmark-Norway during the Napoleonic Wars.
