Thomas Buchanan (November 19, 1808 – September 3, 1841) was the first governor of Liberia and a cousin of James Buchanan, President of the United States.
 He came to Liberia as the envoy of the American Colonization Society in the 1830s.
 He worked first as an administrator in Grand Bassa, which later had its capital named Buchanan in his honor.
 In 1839, Buchanan was sent to Monrovia, where he became the first governor of Liberia after the death of Jehudi Ashmun.
 He served from April 1, 1839 until his death on September 3, 1841.
The Edward J. Roye Building is a wrecked skyscraper on Ashmun Street in the commercial district of Monrovia, the capital city of Liberia.
 Constructed as the headquarters of the True Whig Party, it was renamed the "E.J. Roye Memorial Building" in 1964.
 It is one of the most prominent buildings in the city.
 In the building's earlier years, it included a grand auditorium, and before the 1980 coup d'état, it hosted government meetings such as sessions of the Legislature in 1975, as well as non-governmental conventions such as the Liberian Federation of Trade Unions in 1977.
 It sits in the heart of the city's pre-coup commercial district, near locations such as the former offices of the American Colonization Society.
The McGill family of Monrovia, Liberia, was a free African-American mulatto family from Baltimore, Maryland, who emigrated to Monrovia in the 19th century.
 Among the early American settlers of Liberia, the McGills became established as one of the most prominent early Americo-Liberian families.
 Daguerreotypes of the McGill family can be found in the Library of Congress.
 Members occupied colonial offices, and they are mentioned in the "African Repository" magazine published by the American Colonization Society.
Robert Finley (1772 – October 3, 1817) was briefly the president of the University of Georgia.
 He initiated the American Colonization Society which founded Liberia.
 Finley was born in Princeton, New Jersey, and graduated from College of New Jersey (later renamed Princeton University) at the age of 15.
The Society for the Colonization of Free People of Color of America, commonly known as the American Colonization Society (ACS), was a group established in 1816 by Robert Finley of New Jersey which supported the migration of free African Americans to the continent of Africa.
 It helped to found the colony of Liberia in 1821–22 on the coast of West Africa as a place for free-born or manumitted American blacks.
The Maryland State Colonization Society was the Maryland branch of the American Colonization Society, an organization founded in 1816 with the purpose of returning free African Americans to what many Southerners considered greater freedom in Africa.
 The ACS helped to found the colony of Liberia in 1821–22, as a place for freedmen.
 The Maryland State Colonization Society was responsible for founding the Republic of Maryland in West Africa, a short lived independent state that in 1857 was annexed by Liberia.
 The goal of the society was "to be a remedy for slavery", such that "slavery would cease in the state by the full consent of those interested", but this end was never achieved, and it would take the outbreak of civil war to bring slavery to an end in Maryland.
Eli Ayers (May 9, 1778 – April 25, 1822) was a physician and the first colonial agent of the American Colonization Society in what later became Liberia.
 He was born in 1778 in Shiloh, New Jersey, and married Elizabeth West in 1812.
 He practiced medicine in Woodbury, New Jersey.
 On August 7, 1821, he left New York for West Africa on the USS "Shark".
 Together with Robert F. Stockton of the USS "Alligator" he extorted a treaty under duress with six tribal kings on the purchase of land at Cape Mesurado.
 He served as the colonial agent of the American Colonization society from December 15, 1821, until his death on April 25, 1822.
Monrovia is the capital city of the West African country of Liberia.
 Located on the Atlantic Coast at Cape Mesurado, Monrovia had a population of 1,010,970 as of the 2008 census.
 With 29% of the total population of Liberia, Monrovia is the country's most populous city.
 From January 7, 1822 until the Liberian Declaration of Independence from the American Colonization Society on July 26, 1847 some 3,198 ex-Caribbean slaves settlers from the Lesser Antilles, who had escaped from their slaveholder or were born free, left the Caribbean islands and came to Liberia with the help and support of the American Colonization Society and other establishment organizations.
 The ex-Caribbean slaves came to Liberia to live a better life, to be free, and to establish self-governance.
 The first ex-Caribbean slaves who came to Liberia were from Barbados; some 500 to 1,000 ex-Caribbean slaves arrived in Liberia.
 The second group of settlers who came from the Caribbean islands were from Trinidad and Tobago; they were some 345 ex-Caribbean slaves, followed by some 620 ex-Caribbean slaves from Saint Vincent and the Grenadines.
 Another group of settlers, some 350 ex-Caribbean slaves, came from Saint Kitts and Nevis.
 The last two groups of settlers from the Caribbean islands were some 483 from Grenada and some 400 from Saint Lucia.
 As job opportunities and development growth increased, the ex-Caribbean slaves moved through Grand Cape Mount, Bomi County, Montserrado, Margibi County and other regions of Liberia to seek jobs and other opportunities.
Elliott Cresson (March 2, 1796 – February 20, 1854) was an American philanthropist who gave money to a number of causes after a brief career in the mercantile business.
 He established the Elliott Cresson Medal of the Franklin Institute in 1848, and helped found and manage the Philadelphia School of Design for Women, today's Moore College of Art and Design.
 Cresson was a member of the Religious Society of Friends (Quakers) and a strong supporter of the Philadelphia branch of the American Colonization Society, a group fighting slavery that relocated former slaves and free African Americans to colonies in Liberia.
 Cresson was called "the most belligerent Friend the Society ever had."
Liberia is a country in West Africa which was founded, established, colonized, and controlled by citizens of the United States and ex-Caribbean slaves as a colony for former African American slaves and their free black descendants.
 It is one of only two sovereign countries in the world that were started by citizens and ex-Caribbean slaves of a political power as a colony for former slaves of the same political power, the other being Sierra Leone, established by Great Britain.
 In 1847, Liberia proclaimed its independence from the American Colonization Society (ACS).
