Calvin Coolidge in the context of "1920 Republican National Convention"

Presidential elections were held in the United States on November 2, 1920. The Republican ticket of senator Warren G. Harding of Ohio and governor Calvin Coolidge of Massachusetts defeated the Democratic ticket of governor James M. Cox of Ohio and assistant secretary Franklin D. Roosevelt of New York. It was the first election held after the end of the First World War, and the first election after the ratification of the Nineteenth Amendment gave nationwide suffrage to women.

Incumbent president Woodrow Wilson, a Democrat who had served since 1913, privately hoped for a third term despite severe physical and mental disabilities from a stroke, but he had very little support. Former president Theodore Roosevelt had been the frontrunner for the Republican nomination, but he died in 1919 without leaving an obvious heir to his progressive legacy. The major parties turned to little-known dark horse candidates from the state of Ohio, a populous swing state with many electoral votes. Cox won on the 44th ballot at the 1920 Democratic National Convention, defeating William Gibbs McAdoo (Wilson's son-in-law), A. Mitchell Palmer, and several other candidates. Harding emerged as a compromise candidate between the conservative and progressive wings of the Republican party, and he clinched his nomination on the tenth ballot at the 1920 Republican National Convention.

In the United States, members of the Delano family include U.S. presidents Franklin Delano Roosevelt, Ulysses S. Grant and Calvin Coolidge, astronaut Alan B. Shepard, and writer Laura Ingalls Wilder. Its progenitor is Philippe de Lannoy (1602–1681), a Pilgrim of Walloon descent, who arrived at Plymouth, Massachusetts, in the early 1620s. His descendants also include Eustachius De Lannoy (who played an important role in Indian history), Frederic Adrian Delano, Robert Redfield, and Paul Delano. Delano family forebears include the Pilgrims who chartered the Mayflower, seven of its passengers, and three signers of the Mayflower Compact.

Presidential elections were held in the United States on November 6, 1928. The Republican ticket of former Secretary of Commerce Herbert Hoover and Senator Charles Curtis defeated the Democratic ticket of New York Governor Al Smith and Senator Joseph T. Robinson.

After President Calvin Coolidge declined to seek reelection, Hoover emerged as the Republican Party's frontrunner. As Hoover's party opponents failed to unite around a candidate, Hoover received a large majority of the vote at the 1928 Republican National Convention. The strong state of the economy discouraged some Democrats from running, and Smith was nominated on the first ballot of the 1928 Democratic National Convention. Hoover and Smith had been widely known as potential presidential candidates long before the 1928 campaign, and both were generally regarded as outstanding leaders. Both were newcomers to the presidential race and presented in their person and record an appeal of unknown potency to the electorate. Both faced serious discontent within their respective parties' membership, and both lacked the wholehearted support of their parties' organization.

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.

A national monument is a monument constructed in order to commemorate something of importance to national heritage, such as a country's founding, independence, war, or the life and death of a historical figure. The term may also refer to a specific monument status, such as a national heritage site, by reason of their cultural importance rather than age). National monument status is usually granted to colossal symbols of national identity.

Gorge Dam is one of three along the upper Skagit River in Whatcom County, Washington, and part of the Skagit River Hydroelectric Project that supplies Seattle with some of its power needs. Construction on the original wooden Gorge Dam began in 1921, with its generators formally started by President Calvin Coolidge on September 17, 1924. In 1961, a new Gorge High Dam, made of concrete, was completed to replace the original.

A pivotal scene in the 1974 Warren Beatty film, The Parallax View, was shot at this location.

Paramahansa Yogananda (born Mukunda Lal Ghosh; January 5, 1893 – March 7, 1952) was an Indian and American Hindu monk, yogi, and guru who founded the Self-Realization Fellowship (SRF)/Yogoda Satsanga Society of India (YSS), a religious meditation and Kriya Yoga organization, to disseminate his teachings. A chief disciple of the yoga guru Swami Sri Yukteswar Giri, he was sent by his lineage to spread yogic teachings to the West. He immigrated to the US at the age of 27, intending to demonstrate a unity between Eastern and Western religions and advocate for a balance between Western material growth and Indian spirituality. His longstanding influence on the American yoga movement, and especially the yoga culture of Los Angeles, led yoga experts to consider him the "Father of Yoga in the West". He lived his final 32 years in the US.

Yogananda was among the first Indian religious teachers to settle in the US, and the first prominent Indian to be hosted in the White House (by President Calvin Coolidge in 1927); his early acclaim led to him being dubbed "the 20th century's first superstar guru" by the Los Angeles Times. Arriving in Boston in 1920, he embarked on a successful transcontinental speaking tour before settling in Los Angeles in 1925. For the next two and a half decades, he gained local fame and expanded his influence worldwide: he created a monastic order and trained disciples, went on teaching tours, bought properties for his organization in various California locales, and initiated thousands into Kriya Yoga. By 1952, SRF had over 100 centers in both India and the United States. As of 2012, they had groups in nearly every major American city. His "plain living and high thinking" principles attracted people from all backgrounds among his followers.

The Boston police strike occurred on September 9, 1919, when Boston police officers went on strike seeking recognition for their trade union and improvements in wages and working conditions. Police Commissioner Edwin Upton Curtis denied that police officers had any right to form a union, much less one affiliated with a larger organization like the American Federation of Labor (AFL), which some attribute to concerns that unionized police would not protect the interest of city officials and business leaders. Attempts at reconciliation between the Commissioner and the police officers, particularly on the part of Boston's mayor, Andrew James Peters, failed.

During the strike, Boston experienced several nights of lawlessness. Several thousand members of the Massachusetts State Guard, supported by volunteers, restored order by force. Press reaction both locally and nationally described the strike as Bolshevik-inspired and directed at the destruction of civil society. The strikers were called "deserters" and "agents of Lenin". Samuel Gompers of the AFL recognized that the strike was damaging the cause of labor in the public mind and advised the strikers to return to work. Commissioner Curtis refused to re-hire the striking policemen. He was supported by Massachusetts governor Calvin Coolidge, whose rebuke of Gompers earned him a national reputation.
