Many countries in the New World and elsewhere celebrate the anniversary of Christopher Columbus's arrival in the Americas, which occurred on October 12, 1492, as an official holiday. The event is celebrated as Columbus Day in the United States, as Día de la Raza in many countries in Latin America, as Discovery Day in the Bahamas, as Día de la Hispanidad, Fiesta Nacional in Spain, Día del Respeto a la Diversidad Cultural (Day of Respect for Cultural Diversity) in Argentina and as Día de las Américas (Day of the Americas) in Uruguay. These holidays have been celebrated unofficially since the late 18th century, and officially in various areas since the early 20th century.

Columbus Day first became an official state holiday in Colorado in 1906, and became a federal holiday in 1937, though people have celebrated Columbus' voyage since the colonial period. In 1792, New York City and other U.S. cities celebrated the 300th anniversary of his landing in the New World. President Benjamin Harrison called upon the people of the United States to celebrate Columbus Day on the 400th anniversary of the event. During the four hundredth anniversary in 1892, teachers, preachers, poets and politicians used Columbus Day rituals to teach ideals of patriotism. These patriotic rituals were framed around themes such as support for war, citizenship boundaries, the importance of loyalty to the nation, and celebrating social progress.

Christopher Columbus (before 31 October 1451 – 20 May 1506) was an explorer, colonizer, and navigator, born in the Republic of Genoa, in what is today northwestern Italy. Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean that led to general European awareness of the American continents. Those voyages, and his efforts to establish permanent settlements in the island of Hispaniola, initiated the process of Spanish colonization, which foreshadowed the general European colonization of what became known as the "New World".

In the context of emerging western imperialism and economic competition between European kingdoms seeking wealth through the establishment of trade routes and colonies, Columbus's speculative proposal to reach the East Indies by sailing westward received the support of the Spanish crown, which saw in it a promise, however remote, of gaining the upper hand over rival powers in the contest for the lucrative spice trade with Asia. During his first voyage in 1492, instead of reaching Japan as he had intended, Columbus landed in the Bahamas archipelago, at a locale he named San Salvador. Over the course of three more voyages, Columbus visited the Greater and Lesser Antilles, as well as the Caribbean coast of Venezuela and Central America, claiming them for the Spanish Empire.
