Unincorporated Community
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or uninhabited areas. By country Argentina In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune. Australia Unlike many other countries, Australia has only one level of local government immediately beneath state and territorial governments. A local government area (LGA) often contains several towns and even entire metropolitan areas. Thus, aside from very sparsely populated areas and a few other special cases, almost all of Australia is part of an LGA. Un ...

Arivaca Schoolhouse
The Arivaca Schoolhouse is a historic one-room school building located in the unincorporated community of Arivaca, Arizona, Arivaca, in southern Pima County, Arizona. A small and simple structure made of locally manufactured mud adobe bricks, the Arivaca Schoolhouse was built in 1879 and is the oldest standing schoolhouse remaining in Arizona. It was added to the National Register of Historic Places on April 16, 2012, and is now used as a center for community activities. The Arivaca Schoolhouse was built by Don Pedro Aguirre, an Arizona pioneer that had come to the United States from his native Chihuahua (state), Chihuahua, Mexico, in the 1850s. The school was run by School District No. 2, Pima County. In 1868, Aguirre opened a stagecoach stop for his freighting business near Arivaca and eventually became one of the leading citizens of the community during its period of development in the 1870s. In 1879, Aquirre built the Arivaca Schoolhouse for his own children and those of his em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate an ...

Mexican Revolution
The Mexican Revolution ( es, Revolución Mexicana) was an extended sequence of armed regional conflicts in Mexico from approximately 1910 to 1920. It has been called "the defining event of modern Mexican history". It resulted in the destruction of the Federal Army and its replacement by a revolutionary army, and the transformation of Mexican culture and government. The northern Constitutionalist faction prevailed on the battlefield and drafted the present-day Constitution of Mexico, which aimed to create a strong central government. Revolutionary generals held power from 1920 to 1940. The revolutionary conflict was primarily a civil war, but foreign powers, having important economic and strategic interests in Mexico, figured in the outcome of Mexico's power struggles. The United States played an especially significant role. Although the decades-long regime of President Porfirio Díaz (1876–1911) was increasingly unpopular, there was no foreboding in 1910 that a revolutio ...

United States Cavalry
The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army by an act of Congress on 3 August 1861.Price (1883) p. 103, 104 This act converted the U.S. Army's two regiments of dragoons, one regiment of mounted riflemen, and two regiments of cavalry into one branch of service. The cavalry branch transitioned to the Armored Forces with tanks in 1940, but the term "cavalry", e.g. "armored cavalry", remains in use in the U.S. Army for mounted (ground and aviation) reconnaissance, surveillance, and target acquisition (RSTA) units based on their parent Combat Arms Regimental System (CARS) regiment. ''Cavalry'' is also used in the name of the 1st Cavalry Division for heraldic/lineage/historical purposes. Some combined arms battalions (i.e., consisting of a combination of tank and mechanized infantry companies) are designated as ''armor'' formations, while others are designated as ''infantry'' organizations. These "branch" desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Court Of Private Land Claims
A court is any person or institution, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution, and it is generally understood that all people have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court. The system of courts that interprets and applies the law is collectively known as the judiciary. The place where a court sits is known as a venue. The room where court proceedings occur is known as a courtroom, and the building as a courthouse; court facilities range from simple and very small facilities in rural communities to large complex facilities in urban communities. The practical authority given t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Colorado, Arizona
Cerro Colorado is a ghost town in southern Pima County, Arizona. The town is located off Arivaca Road, near Arivaca, and is best known for the massacre of mining employees by Mexican outlaws and buried treasure. History Cerro Colorado was established around 1855 by Charles D. Poston, who owned the Sonora Exploring & Mining Company in Tubac, Arizona. The most prosperous mine in the area was the Heintzelman Mine, named after Major General Samuel P. Heintzelman, who was the first president of the mining company and later grew famous during the American Civil War. The post office was established on April 17, 1879, and closed on April 15, 1911. In 1861, fifteen Mexican and Native American men were killed after being buried alive in their shaft when the roof caved in. The men were deep within the shaft so no rescue was possible or attempted, this frightened the Mexican employees who felt the mine was haunted so they left and went home to Sonora. Several German and American miners then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Poston
Charles Debrille Poston (April 20, 1825 – June 24, 1902) was an American explorer, prospector, author, politician, and civil servant. He is referred to as the "Father of Arizona" due to his efforts lobbying for creation of the territory. Poston was also Arizona Territory's first Delegate to the U.S. House of Representatives. Background Poston was born near Elizabethtown, Kentucky to Temple and Judith Debrille Poston. His father was a printer and he served as a printer's devil. Poston was orphaned at the age of twelve, and was apprenticed to the local county clerk, Samuel Haycraft. Following his apprenticeship, he moved to Nashville, Tennessee where he clerked for the Tennessee Supreme Court while reading law. Poston married Haycraft's daughter, Margaret, in November 1849 and the couple had a daughter, Sarah Lee Poston, who reached adulthood. Charles Poston was listed in the 1850 census as owning at least one slave. Margaret Poston became paralyzed on February 12, ...

Land Grant
A land grant is a gift of real estate—land or its use privileges—made by a government or other authority as an incentive, means of enabling works, or as a reward for services to an individual, especially in return for military service. Grants of land are also awarded to individuals and companies as incentives to develop unused land in relatively unpopulated countries; the process of awarding land grants are not limited to the countries named below. The United States historically gave out numerous land grants as Homesteads to individuals desiring to prove a farm. The American Industrial Revolution was guided by many supportive acts of legislatures (for example, the Main Line of Public Works legislation of 1826) promoting commerce or transportation infrastructure development by private companies, such as the Cumberland Road turnpike, the Lehigh Canal, the Schuylkill Canal and the many railroads that tied the young United States together. Ancient Rome Roman soldiers were giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pima Indian Revolt
The Pima Revolt, also known as the O'odham Uprising or the Pima Outbreak, was a revolt of Pima native Americans in 1751 against colonial forces in Spanish Arizona and one of the major northern frontier conflicts in early New Spain. Background The revolt culminated from decades of violence by the local Spanish settlers against Indians beginning in 1684. The period was characterized by local Indians' gradual loss of autonomy and territory. Treaties allowing the Spanish to mine and herd on Native lands led to an influx of new settlers; by 1760 Hispanos had become a substantial presence in the present-day American Southwest. However, the colonial province of Sonora was characterized by a larger native population, and more frequent conflict between them and the Spaniards. The Pima Indian Revolt was directly preceded by the Seri Revolt of Seri Indians in Sonora. Uprising While the Pima people had no central authority, the charismatic Luis Oacpicagigua (Luis of Sáric) began th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
