His Excellency: George Washington is a 2004 biography of the first President of the United States, General George Washington.
 It was written by Joseph Ellis, a professor of History at Mount Holyoke College, who specializes in the founding fathers and the revolutionary and federalist periods.
John Jay (December 23 [O.S. December 12] 1745 – May 17, 1829) was an American statesman, Patriot, diplomat, one of the Founding Fathers of the United States, signatory of the Treaty of Paris of 1783, second Governor of New York, and the first Chief Justice of the United States (1789–1795).
 He directed U.S. foreign policy for much of the 1780s and was an important leader of the Federalist Party after the ratification of the United States Constitution in 1788.
Alexander Hamilton (January 11, 1755 or 1757July 12, 1804) was an American statesman and one of the Founding Fathers of the United States.
 He was an influential interpreter and promoter of the U.S. Constitution, as well as the founder of the nation's financial system, the Federalist Party, the United States Coast Guard, and "The New York Post" newspaper.
 As the first Secretary of the Treasury, Hamilton was the main author of the economic policies of the George Washington administration.
 He took the lead in the funding of the states' debts by the Federal government, as well as the establishment of a national bank, a system of tariffs, and friendly trade relations with Britain.
 His vision included a strong central government led by a vigorous executive branch, a strong commercial economy, with a national bank and support for manufacturing, plus a strong military.
 This was challenged by Virginia agrarians Thomas Jefferson and James Madison, who formed a rival party, the Democratic-Republican Party.
 They favored strong states based in rural America and protected by state militias as opposed to a strong national army and navy.
 They denounced Hamilton as too friendly toward Britain and toward monarchy in general, and too oriented toward cities, business and banking.
Beta Delta Alpha (ΒΔΑ, also "BDA") is the first Arab interest fraternity in the United States and North America.
 It was founded in 2014 at the University of California - Los Angeles (UCLA) on April 23, 2014 in Los Angeles, California.
 The fraternity had written its constitution and established its founding fathers on October 11, 2013, which was about six months before the fraternity was approved for induction into UCLA’s Multi-Interest Greek Council, in which one of the founding fathers, Jodutt Basrawi, presented the fraternity's principles to the council.
 The fraternity currently consists of one active chapter at UCLA.
 Beta Delta Alpha’s sister sorority is Epsilon Alpha Sigma (ΕΑΣ, also EAS), the first Arab interest sorority in the United States and North America.
Federalist No. 7 is an essay by Alexander Hamilton, the seventh of "The Federalist Papers".
 It was published on November 15, 1787 under the pseudonym Publius, the name under which all "The Federalist" papers were published.
 Arguing for the importance of the Union to the well-being of Americans, Hamilton addresses a theme begun in Federalist No. 6: the danger of dissension among the states if they remain without a strong federal government.
 No. 7 is titled "The Same Subject Continued: Concerning Dangers from Dissensions Between the States."
Anti-Federalist Papers is the collective name given to works written by the Founding Fathers who were opposed to or concerned with the merits of the United States Constitution of 1787.
 Starting on 25 September 1787 (8 days after the final draft of the US Constitution) and running through the early 1790s, these anti-Federalists published a series of essays arguing against a stronger and more energetic union as embodied in the new Constitution.
 Although less influential than their written counterparts, "The Federalist Papers", these works nonetheless played an important role in shaping the early American political landscape and in the passage of the US Bill of Rights.
Richard Bassett (April 2, 1745 – August 15, 1815) was an American lawyer and political figure from the state of Delaware who, as a veteran of the Revolutionary War and delegate to the Constitutional Convention of 1787, is considered one of the Founding Fathers of the United States.
 A member of the Federalist Party, he served in the Delaware General Assembly, as Governor of Delaware, and as U.S. Senator from Delaware.
 He holds the Senate Rank of 1, as the most senior United States Senator during the First Congress of the United States.
Eric Edward Khasakhala, known as "Omwana wa Kwendo" (26 March 1926 – 14 July 2000) was a Kenyan politician, educationist, Pan Africanist, independence activist, Cabinet Minister and one of the founding fathers of the Republic of Kenya.
 He was a participant of the delegation at the negotiations for Independence at the Lancaster House Conferences; he was instrumental in the formation of Kenya's Kenya African Democratic Union (KADU) party, which he served as one of the party officers.
 The KADU advocated for the federalist post independent Kenya.
El Altar de la Patria, or The Altar of the Homeland, is a white marble mausoleum in Santo Domingo, Dominican Republic that houses the remains of the founding fathers of the Dominican Republic: Juan Pablo Duarte, Francisco del Rosario Sánchez, and Ramón Matías Mella, collectively known as Los Trinitarios.
 Within the mausoleum there are statues of the founding fathers, carved by Italian sculptor Nicholas Arrighini; there is as well an "eternal flame" that is kept lit in memory of the patriots.
 The Altar is within the Baluatre del Conde and is the main attraction of the Parque Independencia (Independence Park).
Douglass Greybill Adair (March 5, 1912 – May 2, 1968) was an American historian who specialized in intellectual history.
 He is best known for his work in researching the authorship of disputed numbers of "The Federalist Papers", and his influential studies in the history and influence of republicanism in the United States during the late eighteenth and early nineteenth centuries—the era of the Enlightenment.
 His most famous essay, "Fame and the Founding Fathers," introduced the pursuit of fame as a new motivation for understanding the actions for the Framers.
