United States And Mexican Boundary Survey
The United States and Mexican Boundary Survey (1848–1855) determined the border between the United States and Mexico as defined in the Treaty of Guadalupe Hidalgo, which had ended the Mexican–American War. The results of the survey were published in the three volumes entitled Report on the United States and Mexican boundary survey, made under the direction of the secretary of the Interior by William H. Emory' (1857-1859). In addition to its documentation of the new boundary, the survey report was notable for its natural history content, including paleontology, botany, ichthyology, herpetology, ornithology, and mammalogy. The survey was also provided to the war department now known as the United States Department of War in order to provide data for building a railroad line. In the report's section titled, "Personal Accounts", a brief description of Panama is also included, along with the experiences he and his men had while conducting the survey, including the experiences of h ...

Treaty Of Guadalupe Hidalgo
The Treaty of Guadalupe Hidalgo ( es, Tratado de Guadalupe Hidalgo), officially the Treaty of Peace, Friendship, Limits, and Settlement between the United States of America and the United Mexican States, is the peace treaty that was signed on 2 February 1848, in the Villa de Guadalupe Hidalgo (now a neighborhood of Mexico City) between the United States and Mexico that ended the Mexican–American War (1846–1848). The treaty was ratified by the United States on 10 March and by Mexico on 19 May. The ratifications were exchanged on 30 May, and the treaty was proclaimed on 4 July 1848. With the defeat of its army and the fall of its capital in September 1847, Mexico entered into negotiations with the U.S. peace envoy, Nicholas Trist, to end the war. On the Mexican side, there were factions that did not concede defeat or seek to engage in negotiations. The treaty called for the United States to pay US$15 million to Mexico and to pay off the claims of American citizens against Mex ...

Mexican–American War
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the (''United States intervention in Mexico''), was an armed conflict between the United States and Mexico from 1846 to 1848. It followed the 1845 American annexation of Texas, which Mexico still considered its territory. Mexico refused to recognize the Velasco treaty, because it was signed by President Antonio López de Santa Anna while he was captured by the Texan Army during the 1836 Texas Revolution. The Republic of Texas was ''de facto'' an independent country, but most of its Anglo-American citizens wanted to be annexed by the United States. Sectional politics over slavery in the United States were preventing annexation because Texas would have been admitted as a slave state, upsetting the balance of power between Northern free states and Southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of expand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of War
The United States Department of War, also called the War Department (and occasionally War Office in the early years), was the United States Cabinet department originally responsible for the operation and maintenance of the United States Army, also bearing responsibility for naval affairs until the establishment of the Navy Department in 1798, and for most land-based air forces until the creation of the Department of the Air Force on September 18, 1947. The Secretary of War, a civilian with such responsibilities as finance and purchases and a minor role in directing military affairs, headed the War Department throughout its existence. The War Department existed from August 7, 1789 until September 18, 1947, when it split into the Department of the Army and the Department of the Air Force. The Department of the Army and Department of the Air Force later joined the Department of the Navy under the United States Department of Defense in 1949. History 18th century The Departme ...

John James Audubon
John James Audubon (born Jean-Jacques Rabin; April 26, 1785 – January 27, 1851) was an American self-trained artist, naturalist, and ornithologist. His combined interests in art and ornithology turned into a plan to make a complete pictorial record of all the bird species of North America. He was notable for his extensive studies documenting all types of American birds and for his detailed illustrations, which depicted the birds in their natural habitats. His major work, a color-plate book titled ''The Birds of America'' (1827–1839), is considered one of the finest ornithological works ever completed. Audubon is also known for identifying 25 new species. He is the eponym of the National Audubon Society, and his name adorns a large number of towns, neighborhoods, and streets across the United States. Dozens of scientific names first published by Audubon are still in use by the scientific community. Early life Audubon was born in Les Cayes in the French colony of Saint-Dom ...

International Boundary And Water Commission
The International Boundary and Water Commission ( es, links=no, Comisión Internacional de Límites y Aguas) is an international body created by the United States and Mexico in 1889 to apply the rules for determining the location of their international boundary when meandering rivers transferred tracts of land from one bank to the other, as established under the Convention of November 12, 1884.

Pacific Railroad Surveys
The Pacific Railroad Surveys (1853–1855) were of a series of explorations of the American West designed to find and document possible routes for a transcontinental railroad across North America. The expeditions included surveyors, scientists, and artists and resulted in an immense body of data covering at least on the American West. "These volumes... constitute probably the most important single contemporary source of knowledge on Western geography and history and their value is greatly enhanced by the inclusion of many beautiful plates in color of scenery, native inhabitants, fauna and flora of the Western country." Published by the United States War Department from 1855 to 1860, the surveys contained significant material on natural history, including many illustrations of reptiles, amphibians, birds, and mammals. In addition to describing the route, these surveys also reported on the geology, zoology, botany, paleontology of the land as well as provided ethnographic descriptions ...

Mexico–United States Border
The Mexico–United States border ( es, frontera Estados Unidos–México) is an international border separating Mexico and the United States, extending from the Pacific Ocean in the west to the Gulf of Mexico in the east.

The Mexico–United States border is the most frequently crossed border in the world, with approximately 350 million documented crossings annually. It is the tenth-longest border between two countries in the world. The total length of the continental border is . From the Gulf of Mexico, it follows the course of the Rio Grande (Río Bravo del Norte) to the border crossing at Ciudad Juárez, Chihuahua, and El Paso, Texas. Westward from El Paso–Juárez, it crosses vast tracts of the Chihuahuan and Sonoran deserts to the Colorado River Delta and San Diego–Tijuana, before reaching the Pacific Ocean.

Exploration Of North America
The exploration of North America by European sailors and geographers was an effort by major European powers to map and explore the continent with the goal of economic, religious and military expansion. The combative and rapid nature of this exploration is the result of a series of countering actions by neighboring European nations to ensure no single country had garnered enough wealth and power from the Americas to militarily tip the scales over on the European continent. It spanned the late 15th to early 17th centuries, and consisted primarily of expeditions funded by Spain, England, France, and Portugal. See also the European colonization of the Americas. Pre-Columbian exploration According to the Sagas of Icelanders, Norse sailors (often called Vikings) from Iceland first settled Greenland in the 980s. Erik the Red explored and settled southwestern Greenland, which he named to entice potential Icelandic settlers, eventually establishing the Eastern and Western Settlements, whic ...
