Timeline of the American Old West

1864 Dower hand-colored map depicting the western half of the United States including most of the lands west of the Mississippi River.

This timeline of the American Old West is a chronologically ordered list of events significant to the development of the American West as a region of the United States prior to 1912. The term "Old West" refers to a vast geographical area and lengthy time period of imprecise boundaries, and historians' definitions vary. The events in this timeline occurred primarily in the contiguous portion of the modern United States west of the Mississippi River, and mostly in the period between the Louisiana Purchase in 1803 and the admission of the last mainland states into the Union in 1912. A small section summarizing early exploration and settlement prior to 1803 is included to provide a foundation for later developments. Rarely, events significant to the history of the West but which occurred within the modern boundaries of Canada and Mexico are included as well.

Western North America was inhabited for millennia by various groups of Native Americans, and later served as a frontier to European powers, beginning with Spanish colonization in the 16th century. British, French, and Russian claims followed in the 18th and 19th centuries. After the American Revolution, the newly independent United States began securing its own frontier from the Appalachian Mountains westward for settlement and economic investment by American citizens. The long history of American expansion into these lands has played a central role in shaping American culture, iconography, and the modern national identity, and remains a popular topic for study by scholars and historians.

Events listed below are notable developments for the region as a whole, not just for a particular state or smaller subdivision of the region; as historians Hine and Faragher put it, they "tell the story of the creation and defense of communities, the use of the lands, the development of markets, and the formation of states.... It is a tale of conquest, but also one of survival, persistence, and the merging of peoples and cultures."^[1]

For almost three centuries after Columbus' voyages to the New World, much of western North America remained unsettled by European colonists, despite various territorial claims made by imperialist nations. Europeans interest in the vast territory was primarily motivated by the search for precious metals, especially gold, and the fur trade, with miners, trappers, and hunters among the first people of European descent to permanently settle in the West.^[2]:150 The early years were also a period of scientific exploration and survey, such that by 1830 the rough outline of the western half of the continent had been mapped to the Pacific Ocean.^[2]:162

Year	Date	Event
1540	Feb 23	Spanish conquistador Francisco Vázquez de Coronado embarks on an expedition into the unexplored territory north of colonized Mexico to search for the fabled Seven Cities of Gold. The voyage lasts more than two years, during which Coronado travels through much of the American Southwest and as far north as present-day Kansas. His party is the first to document the geography and indigenous peoples of significant portions of the West.[3]
1598	Apr	Spanish explorer Juan de Oñate establishes Nuevo México in the region around the upper Rio Grande as the northernmost province of New Spain, serving as its first colonial governor.[4]
1607		Spanish colonists establish the city of Santa Fe in the province of Santa Fe de Nuevo México.[5]

More than 400 people are killed and the Spanish are unable to reconquer Santa Fe for another 12 years.[7]
1692		Santa Fe is formally repossessed by the Spanish after Diego de Vargas negotiates a peace with the Pueblo Indians. The following six years witness a difficult reinstatement of Spanish and Franciscan rule over the Pueblos, including another revolt in 1696, which is successfully countered by De Vargas and his forces.[8][9]

By 1823, the missionaries successfully plant a series of 20 more missions along the coast of what becomes the Spanish province of Alta California. These missions bring European culture to the indigenous peoples of California, but also enable a serious decline of from one-third to one-half of the indigenous population there during the Mission period.[13][14]
1779	Sep 3	Comanche Indian leader Cuerno Verde is killed in combat with Spanish forces led by Juan Bautista de Anza in what is now Pueblo County, Colorado.[15]
