William Howard Taft in the context of "Secretary of war"

The United States involvement in the Mexican Revolution was varied and seemingly contradictory, first supporting and then repudiating Mexican regimes during the period 1910–1920. For both economic and political reasons, the U.S. government generally supported those who occupied the seats of power, but could withhold official recognition. The U.S. supported the regime of Porfirio Díaz (1876–1880; 1884–1911) after initially withholding recognition since he came to power by coup. In 1909, Díaz and U.S. President Taft met in Ciudad Juárez, across the border from El Paso, Texas. Prior to Woodrow Wilson's inauguration on March 4, 1913, the U.S. Government focused on just warning the Mexican military that decisive action from the U.S. military would take place if lives and property of U.S. nationals living in the country were endangered. President William Howard Taft sent more troops to the US-Mexico border but did not allow them to intervene directly in the conflict, a move which Congress opposed. Twice during the Revolution, the U.S. sent troops into Mexico, to occupy Veracruz in 1914 and to northern Mexico in 1916 in a failed attempt to capture Pancho Villa. U.S. foreign policy toward Latin America was to assume the region was the sphere of influence of the U.S., articulated in the Monroe Doctrine. However the U.S. role in the Mexican Revolution has been exaggerated. It did not directly intervene in the Mexican Revolution in a sustained manner.

During Díaz's long rule, he implemented policies aimed at modernization and economic development, inviting foreign entrepreneurs to invest in Mexico. The regime passed laws favorable to investors. American business interests invested large amounts of capital, particularly along the U.S.-Mexico border, during the decades of Díaz's rule. There was close economic cooperation between the two governments, which was predicated on Diaz's cooperation with US investors. In 1908 Díaz stated he would not run for re-election in 1910; the statement gave rise to politicking of potential candidates. Díaz reversed himself, ran for re-election, and jailed the leading opposition candidate, Francisco I. Madero. Madero escaped Mexico and took refuge in San Antonio, Texas, and called for nullification of the 1910 elections, declared himself as provisional president, and asked for support from the Mexican people. His Plan of San Luis Potosí sparked revolutionary uprisings, particularly in Mexico's north. The U.S. stayed out of the unfolding events until March 6, 1911, when President William Howard Taft mobilized forces on the U.S.-Mexico border. "In effect this was an intervention in Mexican politics, and to Mexicans it meant the United States had condemned Díaz."

Independence Hall is a historic civic building in Philadelphia, Pennsylvania, where both the Declaration of Independence and the Constitution of the United States were debated and adopted by the Founding Fathers of the United States. The building, which is the centerpiece of Independence National Historical Park, was designated a World Heritage Site in 1979. It is an example of American Georgian architecture, which is characterized by symmetry, classical proportions, and exposed brick with stone masonry accents.

Independence Hall, which was initially called Pennsylvania State House, was completed in 1733. It was the first capitol of the colonial era Province of Pennsylvania and, even then, was seen as "the greatest ornament in the town". The building became a symbol of liberty, democracy, and the founding of the United States. During the American Revolutionary War, the Second Continental Congress convened in Independence Hall from 1775 to 1781. They founded the Continental Army inside Independence Hall on June 14, 1775, and the Declaration of Independence was adopted there on July 4, 1776. From May 25 to September 17, 1787, Independence Hall hosted the Constitutional Convention, where the U.S. Constitution was debated, drafted, and ratified. In 1915, former U.S. president William Howard Taft presided over a convention at Independence Hall, where the League to Enforce Peace was formed.

The Supreme Court Building houses the Supreme Court of the United States, the highest court in the federal judiciary of the United States. The building serves as the official workplace of the chief justice of the United States and the eight associate justices of the Supreme Court. It is located at 1 First Street in Northeast Washington, D.C. It is one block immediately east of the United States Capitol and north of the Library of Congress. The building is managed by the Architect of the Capitol. On May 4, 1987, the Supreme Court Building was designated a National Historic Landmark.

Designed in the neoclassical style, the proposal for a separate building for the Supreme Court was suggested in 1912 by President William Howard Taft, who became Chief Justice in 1921. In 1929, Taft successfully argued for the creation of the new building but did not live to see it built. Physical construction began in 1932 and was officially completed in 1935 under the guidance of Chief Justice Charles Evans Hughes, Taft's successor. The building was designed by architect Cass Gilbert, a friend of Taft.

Robert Alphonso Taft Sr. (September 8, 1889 – July 31, 1953) was an American politician, lawyer, and scion of the Republican Party's Taft family. Taft represented Ohio in the United States Senate, briefly served as Senate majority leader, and was a leader of the conservative coalition of Republicans and conservative Democrats who blocked expansion of the New Deal. Often referred to as "Mr. Republican", he co-sponsored the Taft–Hartley Act of 1947, which banned closed shops, created the concept of right-to-work states, and regulated other labor practices.

The elder son of William Howard Taft, the 27th president of the United States and 10th chief justice of the United States, Robert Taft was born in Cincinnati, Ohio. He pursued a legal career in Cincinnati after graduating from Harvard Law School in 1913. With his brother Charles Phelps Taft II, he co-founded the law partnership of Taft Stettinius & Hollister. Taft served in the Ohio House of Representatives from 1921 to 1931 and in the Ohio Senate from 1931 to 1933. Though he lost re-election in 1932, he remained a powerful force in state and local politics.

The Oval Office is the formal working space of the president of the United States at the White House in Washington, D.C. Part of the Executive Office of the President, it is located at the southeast corner of the West Wing.

A new Oval Office was the idea of President Franklin D. Roosevelt, and was designed by architect Eric Gugler as part of a 1933-34 expansion of the West Wing. President William Howard Taft had built a 1909 Oval Office at the center of the south side of the West Wing, but it was damaged in a 1929 fire. The new office offered FDR, who used a wheelchair, easier access, more privacy, and much more natural light. The Taft Oval Office was demolished in Gugler's expansion of the West Wing, and the space became additional staff offices.

International relations between Japan and the United States began in the late 18th and early 19th century with the 1852–1855 diplomatic but force-backed missions of U.S. ship captains James Glynn and Matthew C. Perry to the Tokugawa shogunate. Following the Meiji Restoration, the countries maintained relatively cordial relations. Potential disputes were resolved. Japan acknowledged American control of Hawaii and the Philippines, and the United States reciprocated regarding Korea. Disagreements about Japanese immigration to the U.S. were resolved in 1907. The two were allies against Germany in World War I.

From as early as 1879 and continuing through most of the first four decades of the 20th century, influential Japanese statesmen such as Prince Iesato Tokugawa (1863–1940) and Baron Eiichi Shibusawa (1840–1931) led a major Japanese domestic and international movement advocating goodwill and mutual respect with the United States. Their friendship with the U.S. included allying with seven U.S. presidents – Grant, Theodore Roosevelt, Taft, Wilson, Harding, Hoover, and Franklin D. Roosevelt. It was only after the passing of this older generation of diplomats and humanitarians, along with the evidence that many Americans believed all Asians to be alike with President Calvin Coolidge's signing of the Immigration Act of 1924 that Japanese militarists were able to gain control and pressure Japan into joining with the Axis powers in World War II.

José Victoriano Huerta Márquez (Spanish pronunciation: [biɣtoˈɾjano ˈweɾta]; 23 December 1850 – 13 January 1916) was a Mexican general, politician, engineer, and dictator who served as the 39th President of Mexico from 1913 to 1914 and came to power by coup against the democratically elected government of Francisco I. Madero with the aid of other Mexican generals and the U.S. Ambassador to Mexico. Establishing a military dictatorship, his violent seizure of power set off a new wave of armed conflict in the Mexican Revolution.

After a military career under President and dictator Porfirio Díaz and Interim President Francisco León de la Barra, Huerta became a high-ranking officer during the presidency of Madero during the first phase of the Mexican Revolution (1911–13). In February 1913, Huerta joined a conspiracy against Madero, who entrusted him to control a revolt in Mexico City. The Ten Tragic Days – actually fifteen days – saw the forced resignation of Madero and his vice president and their murders. The coup was backed by the German Empire as well as the United States under the Taft administration. But the succeeding Wilson administration refused to recognize the new regime which had come to power by coup. The U.S. allowed arms sales to rebel forces. Many foreign powers did recognize the regime, including Britain and Germany, but withdrew further support when revolutionary forces started to show military success against the regime; their continuing support of him threatened their own relationships with the U.S. government.

Arthur MacArthur Jr. (June 2, 1845 – September 5, 1912) was a lieutenant general of the United States Army. He became the military Governor-General of the American-occupied Philippines in 1900; his term ended a year later due to clashes with the civilian governor, future-U.S. President William Howard Taft.

His son, Douglas MacArthur, was one of only five men promoted to the five-star rank of General of the Army during World War II. In addition to their both being promoted to the rank of general officer, Arthur MacArthur Jr. and Douglas MacArthur also share the distinction of having been the first father and son to each be awarded a Medal of Honor.

Charles Evans Hughes (April 11, 1862 – August 27, 1948) was an American politician, academic, and jurist who served as the 11th chief justice of the United States from 1930 to 1941. A member of the Republican Party, he previously was the 36th governor of New York (1907–1910), an associate justice of the Supreme Court (1910–1916), and 44th U.S. secretary of state (1921–1925). He was the Republican nominee in the 1916 presidential election, narrowly losing to incumbent president Woodrow Wilson.

Born to a Welsh immigrant preacher and his wife in Glens Falls, New York, Hughes graduated from Brown University and Columbia Law School and practiced law in New York City. After working in private practice for several years, in 1905 he led successful state investigations into public utilities and the life insurance industry. He won election as the governor of New York in 1906, and implemented several progressive reforms. In 1910, President William Howard Taft appointed Hughes as an associate justice of the Supreme Court of the United States. During his tenure on the Supreme Court, Hughes often joined Associate Justice Oliver Wendell Holmes Jr. in voting to uphold state and federal regulations.
