STATES AND TERRITORIES OF THE UNITED STATES (COLORADO).

In this post we will looking at Colorado and its territories, Its present and past governors and House of representative’s members.

INTRODUCTION.

The Territory of Colorado was organized on February 28, 1861 and on August 1, 1876, U.S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the “Centennial State” because it became a state one century after the signing of the United States Declaration of Independence. Colorado is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south, and Utah to the west, as well as touching Arizona to the southwest at the Four Corners. Colorado is noted for its vivid landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers, and desert lands. Colorado is one of the Mountain States, and is a part of the western and southwestern United States. Denver is the capital of and most populous city in Colorado. Residents of the state are known as Coloradans, although the antiquated “Coloradoan” is occasionally used. Colorado is a comparatively wealthy state, ranking eighth in household income in 2016 and 11th in per capita income in 2010. It also ranks highly in the nation’s standard of living index. Major parts of the economy include government and defense, mining, agriculture, tourism, and increasingly other kinds of manufacturing. With increasing temperatures and decreasing water availability, Colorado’s agriculture, forestry, and tourism economies are expected to be heavily affected by climate change. The Spanish Empire claimed Colorado as part of its New Mexico province before U.S. involvement in the region. The U.S. acquired a territorial claim to the eastern Rocky Mountains with the Louisiana Purchase from France in 1803. This U.S. claim conflicted with the claim by Spain to the upper Arkansas River Basin as the exclusive trading zone of its colony of Santa Fe de Nuevo México. In 1806, Zebulon Pike led a U.S. The U.S. relinquished its claim to all land south and west of the Arkansas River and south of 42nd parallel north and west of the 100th meridian west as part of its purchase of Florida from Spain with the Adams-Onís Treaty of 1819. The treaty took effect on February 22, 1821. Having settled its border with Spain, the U.S. admitted the southeastern portion of the Territory of Missouri to the Union as the state of Missouri on August 10, 1821. The remainder of Missouri Territory, including what would become northeastern Colorado, became an unorganized territory and remain so for 33 years over the question of slavery. After 11 years of war, Spain finally recognized the independence of Mexico with the Treaty of Córdoba signed on August 24, 1821. Mexico eventually ratified the Adams–Onís Treaty in 1831. The Texian Revolt of 1835–36 fomented a dispute between the U.S. and Mexico which eventually erupted into the Mexican–American War in 1846. Mexico surrendered its northern territory to the U.S. with the Treaty of Guadalupe Hidalgo after the war in 1848.

COLORADO TERRITORIES.

The Territory of Colorado was an organized incorporated territory of the United States that existed from February 28, 1861, until August 1, 1876, when it was admitted to the Union as the State of Colorado. The territory was organized in the wake of the Pike’s Peak Gold Rush of 1858–1861, which brought the first large concentration of white settlement to the region. The organic act creating the territory was passed by Congress and signed by President James Buchanan on February 28, 1861, during the secessions by Southern states that precipitated the American Civil War. The boundaries of the Colorado Territory were identical with those of the current State of Colorado. The organization of the territory helped solidify Union control over a mineral-rich area of the Rocky Mountains. Statehood was regarded as fairly imminent, but territorial ambitions for statehood were thwarted at the end of 1865 by a veto by President Andrew Johnson. Statehood for the territory was a recurring issue during the Ulysses Grant administration, with Grant advocating statehood against a less willing Congress during Reconstruction. The Colorado Territory ceased to exist when the State of Colorado was admitted to the Union in 1876. East of the Continental Divide, the new territory included the western portion of the Kansas Territory, as well as some of the southwestern Nebraska Territory, and a small parcel of the northeastern New Mexico Territory. On the western side of the divide, the territory included much of the eastern Utah Territory, all of which was strongly controlled by the Ute and Shoshoni. The Eastern Plains were held much more loosely by the intermixed Cheyenne and Arapaho, as well as by the Pawnee, Comanche and Kiowa. In 1861, ten days before the establishment of the territory, the Arapaho and Cheyenne agreed with the U.S. to give up most their areas of the plains to white settlement but were allowed to live in their larger traditional areas, so long as they could tolerate homesteaders near their camps. By the end of the American Civil War in 1865, the Native American presence had been largely eliminated from the High Plains.

LIST OF GOVERNORS AND HOUSE OF REPRESENTATIVE’S MEMBERS

Seven people served as governor of Colorado Territory over eight terms, appointed by the president of the United States. Since statehood, there have been 38 governors, serving 43 distinct terms. One governor Alva Adams served three non-consecutive terms, while John Long Routt, James Hamilton Peabody, and Edwin C. Johnson each served during two non-consecutive periods. The longest-serving governors were Richard “Dick” Lamm (1975–1987) and Roy Romer (1987–1999), who each served 12 years over three terms. The shortest term occurred on March 16 and 17, 1905, when the state had three governors in the span of 24 hours: Alva Adams won the election, but soon after he took office, the legislature declared his opponent, James Hamilton Peabody, governor, but on the condition that he immediately resign, so that his lieutenant governor, Jesse McDonald, could be governor. Thus, Peabody served less than a day as governor. The current governor is Democrat Jared Polis, who took office on January 8, 2019. The Territory of Colorado was organized on February 28, 1861, from parts of the territories of New Mexico, Utah, and Nebraska, and the unorganized territory that was previously the western portion of Kansas Territory.
