Context paragraphs:
Lagos Treaty of Cession: The Treaty of Cession, 6 August 1861 or the Lagos Treaty of Cession was a treaty between Great Britain (represented by Norman B. Bedingfield, Commander of HMS Prometheus and William McCoskry, Acting Consul to Lagos) and Oba Dosunmu of Lagos (spelled 'Docemo' in British documents) representing Lagos.

Monarchy of Ireland: A monarchical system of government existed in Ireland from ancient times until, for what became the Republic of Ireland, the mid-twentieth century.  Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.  The Gaelic kingdoms of Ireland ended with the Norman invasion of Ireland, when the kingdom became a fief of the Holy See under the Lordship of the King of England.  This lasted until the Parliament of Ireland conferred the crown of Ireland upon King Henry VIII of England during the English Reformation.  The monarch of England held the crowns of England and Ireland in a personal union.  The Union of the Crowns in 1603 expanded the personal union to include Scotland.  The personal union between England and Scotland became a political union with the enactments of the Acts of Union 1707, which created the Kingdom of Great Britain.  The crowns of Great Britain and Ireland remained in personal union until it was ended by the Acts of Union 1800, which united Ireland and Great Britain into the United Kingdom of Great Britain and Ireland from January 1801 until December 1922.

Anglo-French War (1778–1783): The Anglo-French War was a military conflict fought between France and Great Britain with their respective allies between 1778 and 1783.  In 1778, France signed a treaty of friendship with the United States.  Great Britain was then at war with France, and in 1779 it was also at war with Spain.  As a consequence, Great Britain was forced to divert resources used to fight the war in North America to theatres in Europe, India and the West Indies, and to rely on what turned out to be the chimera of Loyalist support in its North American operations.  From 1778 to 1783, with or without their allies, France and Britain fought over dominance in the English Channel, the Mediterranean, the Indian Ocean and the West Indies.

Polignac Memorandum: The Polignac Memorandum was a document by George Canning (British Foreign Secretary) written in October 1823, stating that Great Britain had no intention of aiding Spain in the retention of her colonies in Latin and South America.  The document was a result of talks with Prince Jules de Polignac, the French Ambassador to Great Britain.  Both countries (France and Great Britain) agreed that there was no hope of Spain recovering her colonies in the Americas, that neither nation had any desire to gain territory in the region, or gain exclusive commercial treaties.  Canning was then able to advise King George IV to extend diplomatic recognition to Buenos Aires, Colombia, and Mexico, and authorize British ministers in South America to negotiate with their respective states for commercial treaties.

Jesse Fish: Jesse Fish (1724 or 1726–1790) was a shipmaster, merchant, and realtor who lived in St. Augustine, Florida under both Spanish and British rule, and is infamous in the town's history to this day.  He was a schemer involved in contraband trade and illegal real estate deals, and operated as a slaver, smuggler, and usurer.  By his slaver activities Fish introduced most of the "bozales", or African-born slaves, registered in Spanish Florida during the decade (1752–1763) preceding Spain's cession of Florida to Great Britain.  He has been accused of spying for England and Spain as a double agent during the Seven Years’ War, but there is no evidence to support the claim.

New France: New France (French: "Nouvelle-France" ) was the area colonized by France in North America during a period beginning with the exploration of the Gulf of Saint Lawrence by Jacques Cartier in 1534 and ending with the cession of New France to Great Britain and Spain in 1763.

Oglethorpe Plan: James Edward Oglethorpe founded the Georgia Colony, and the town of Savannah, on February 12, 1733 (February 1, 1732 by the Julian calendar used in the British colonies until September 2, 1752).  The new Georgia colony was authorized under a grant from George II to a group constituted by Oglethorpe as the Trustees for the Establishment of the Colony of Georgia in America, or simply the Georgia Trustees.  The new colony was bounded by the Savannah River on the north and the Altamaha River to the south, while the western boundary reached almost to the Mississippi River and lands claimed by France as part of Louisiana.  Not until 1763 did the French formally cede this territory east of the Mississippi to Great Britain, but Spain still claimed a considerable portion of it.  Much of the territory ultimately became American in 1795, when the United States resolved its West Florida boundary dispute with Spain.

Michel Sarrazin: Michel Sarrazin, (5 September 1659 – 8 September 1734), was an early Canadian surgeon, physician, scientist and naturalist.  Born in Nuits-sous-Beaune in the province of Burgundy, he immigrated at age 25 to the colony of New France as a surgeon.  He remained in the colony for the rest of his life, returning to France only during two brief periods.  While in New France, his medical skills were constantly in demand, and he quickly rose in the ranks, becoming one of the colonial elite.  He was both a seigneur and a member of the Conseil Superieur, and held considerable influence in the colony.  He had a great interest in botany, and kept up a frequent correspondence with the Académie Royale des Sciences in France, sending fellow scientists numerous specimens of North American plants, as well as detailed descriptions of dissections of animals.  Sarrazin developed a vast knowledge of both the cultural and natural world of New France, and is credited being one of the first scientists to systematically catalogue ecosystems and samples found in New France, resulting in many important botanical discoveries.

List of mammals of Great Britain: This is a list of mammals of Great Britain.  The Great Britain mammal fauna is somewhat impoverished compared to that of continental Europe due to the short period of time between the last ice age and the flooding of the land bridge between Great Britain and the rest of Europe.  Only those land species which crossed before the creation of the English Channel and those introduced by humans exist in Great Britain.

Continental System: The Continental System or Continental Blockade (known in French as "Blocus continental") was the foreign policy of Napoleon I of France in his struggle against Great Britain during the Napoleonic Wars.  As a response to the naval blockade of the French coasts enacted by the British government on 16 May 1806, Napoleon issued the Berlin Decree on 21 November 1806, which brought into effect a large-scale embargo against British trade.  The embargo was effective intermittently.  It ended on 11 April 1814 after Napoleon's first abdication.  In terms of economic damage to Great Britain, the blockade was largely ineffective; however, British exportations to the continent saw a loss from 25% to 55% of their total value in between the years 1802 and 1806.  As Napoleon realized that extensive trade was going through Spain and Russia, he invaded those two countries.  His forces were tied down in Spain — in which the Spanish War of Independence was occurring simultaneously — and suffered severely in, and ultimately retreated from, Russia in 1812.
