The Treaty of Fort Wayne, sometimes called the Ten O'clock Line Treaty or the Twelve Mile Line Treaty, is an 1809 treaty that obtained 3,000,000 acres (approximately 12,000 km²) of American Indian land for the white settlers of Illinois and Indiana.
 The tribes involved were the Delaware, Eel River, Miami tribe, and Potawatomi in the initial negotiations; later Kickapoo and the Wea, who were the primary inhabitants of the region being sold.
 The negotiations did not include the Shawnee who were minor inhabitants of the area purchased and had been asked to leave the area previously by Miami War Chief Little Turtle.
 Territorial Governor William Henry Harrison negotiated the treaty with the tribes.
 The treaty led to a war with the United States began by Shawnee leader Tecumseh and other dissenting tribesmen in what came to be called "Tecumseh's War".
The Anglo-Ethiopian Treaty of 1897 (sometimes called the Rodd Treaty) was an agreement negotiated between diplomat Sir Rennell Rodd of Great Britain and Emperor Menelik II of Ethiopia primarily involving border issues between Ethiopia and British Somaliland.
 It was signed on 14 May 1897 in order to "strengthen and render more effective and profitable the friendship between the two kingdoms", according to its preamble.
The Courageous" class, sometimes called the Glorious" class, was the first multi-ship class of aircraft carriers to serve with the Royal Navy.
 The three ships—"Furious" , "Courageous" and "Glorious" —were originally laid down as "large light cruisers" (battlecruisers) to be used in the Baltic Project during the First World War.
 While very fast, their minimal armour and few guns limited their long-term utility in the post-war Royal Navy, and they were laid up after the war.
 They were considered capital ships by the terms of the 1922 Washington Naval Treaty and were included in the total amount of tonnage allowed to the Royal Navy.
 Rather than scrap them, the Navy decided to convert them to aircraft carriers as permitted under the Treaty.
The Treaty of Schönbrunn (French: "Traité de Schönbrunn" ; German: "Friede von Schönbrunn" ), sometimes known as the Treaty of Vienna, was signed between France and Austria at Schönbrunn Palace near Vienna on 14 October 1809.
 The treaty ended the Fifth Coalition during the Napoleonic Wars, after Austria had been defeated at the decisive Battle of Wagram on July 5/6.
At the Battle of Edington an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeated the Great Heathen Army led by Guthrum on a date between 6 and 12 May AD 878, soon resulting in the Treaty of Wedmore later the same year.
 The primary sources locate the battle at ""Ethandun"" or ""Ethandune"", and until a scholarly consensus identified its location with the present-day Edington in Wiltshire it was known as the Battle of "Ethandun", a name which continues to be used.
The Egyptian–Hittite peace treaty, also known as the Eternal Treaty or the Silver Treaty, is the only ancient Near Eastern treaty for which both sides' versions have survived.
 It is sometimes called the Treaty of Kadesh after the well-documented Battle of Kadesh fought some sixteen years earlier, although Kadesh is not mentioned in the text.
 Both sides of the treaty have been the subject of intensive scholarly study.
 The treaty itself did not bring about a peace; in fact "an atmosphere of enmity between Hatti and Egypt lasted many years," until the eventual treaty of alliance was signed.
Nuclear latency or a Nuclear threshold state is the condition of a country possessing the technology to quickly build nuclear weapons, without having actually yet done so.
 Because such latent capability is not proscribed by the Nuclear Non-Proliferation Treaty, this is sometimes called the "Japan Option" (as a work-around to the treaty), as Japan is considered a paranuclear state being a clear case of a country with complete technical prowess to develop a nuclear weapon quickly, or as it is sometimes called "being one screwdriver's turn" from the bomb, as Japan is considered to have the materials, expertise and technical capacity to make a nuclear bomb at will.
The Peace of Wedmore is a term used by historians for an event referred to by the monk Asser in his Life of Alfred, outlining how in 878 the Viking leader Guthrum was baptised and accepted Alfred as his adoptive father.
 Guthrum agreed to leave Wessex and a "Treaty of Wedmore" (sometimes called the "Treaty of Chippenham") is often assumed by historians to have existed.
 No such treaty still exists.
 However, there is a document not specifically linked to Wedmore that is a Treaty of Alfred and Guthrum.
The Treaty of Aix-la-Chapelle of 1748, sometimes called the Treaty of Aachen, ended the War of the Austrian Succession following a congress assembled on 24 April 1748 at the Free Imperial City of Aachen, called "Aix-la-Chapelle" in French and then also in English, in the west of the Holy Roman Empire.
 The resulting treaty was signed on 18 October 1748 by Great Britain, France, and the Dutch Republic.
 Two implementation treaties were signed at Nice on 4 December 1748 and 21 January 1749 by Austria, Spain, Sardinia, Modena, and Genoa.
The Carnatic Treaty was signed on 26 July 1801.
 Based on the terms of the treaty, the Nawab of Arcot (sometimes called the Nawab of the Carnatic) ceded all his lands to British rule, including the territory of the polygars.
 He was retained one-fifth of the revenues of the country, amounting to 12 lakhs p.a in exchange.
