California Gold Rush
The California Gold Rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood, in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation and the California genocide. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii) and Latin America in late 1848. ...

Latin America
Latin America or * french: Amérique Latine, link=no * ht, Amerik Latin, link=no * pt, América Latina, link=no, name=a, sometimes referred to as LatAm is a large cultural region in the Americas where Romance languages — languages derived from Latin — are predominantly spoken. The term was coined in the nineteenth century, to refer to regions in the Americas that were ruled by the Spanish Empire, Spanish, Portuguese Empire, Portuguese and French colonial empire#The Americas, French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America plus Brazil (Portuguese America). The term "Latin America" is broader than categories such as ''Hispanic America'', which specifically refers to Spanish-speaking countries; and ''Ibero-America'', which specifically refers to both Spanish and Portuguese-speaking countries while leaving ...

Rancho San Francisco
Rancho San Francisco was a land grant in present-day northwestern Los Angeles County and eastern Ventura County, California. It was a grant of by Governor Juan B. Alvarado to Antonio del Valle, a Mexican army officer, in recognition for his service to Alta California. It is not related to the city of San Francisco. The rancho is the location of the first popularly known finding of gold in the Southern California area in 1842, in Placerita Canyon. Much of the present day city of Santa Clarita lies within the boundary of what was Rancho San Francisco. The adobe headquarters of the rancho, and the site of the gold find (known today as the "Oak of the Golden Dream"), are designated California Historical Landmarks. The rancho included portions of the San Gabriel, Santa Susana, Topatopa, and Sierra Pelona Mountain ranges. Early history After Mission San Fernando Rey de España was established in 1797, the administrators there realized they would need more land for agriculture an ...

Gold In California
Gold became highly concentrated in California, United States as the result of global forces operating over hundreds of millions of years. Volcanoes, tectonic plates and erosion all combined to concentrate billions of dollars' worth of gold in the mountains of California. During the California Gold Rush, gold-seekers known as "Forty-Niners" retrieved this gold, at first using simple techniques, and then developing more sophisticated techniques, which spread around the world. Geology Geologic evidence indicates that over a span of at least 400 million years, gold that had been widely dispersed in the Earth's crust became more concentrated by geologic actions into the gold-bearing regions of California. Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto western North America to build California lay at the bottom of a large sea. Subsea volcanoes deposited lava and minerals (including gold) onto the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California And The Railroads
The establishment of America's transcontinental rail lines securely linked California to the rest of the country, and the far-reaching transportation systems that grew out of them during the century that followed contributed to the state's social, political, and economic development. When California was admitted as a state to the United States in 1850, and for nearly two decades thereafter, it was in many ways isolated, an outpost on the Pacific, until the first transcontinental railroad was completed in 1869. Passenger rail transportation declined in the early- and mid-20th Century with the rise of the state's car culture and road system. It has since undergone something of a renaissance, with the introduction of services such as Metrolink, Coaster, Caltrain, Amtrak California, and others. On November 4, 2008, the People of California passed Proposition 1A, which helped provide financing for a high-speed rail line. 19th century Background The early Forty-Niners of the Calif ...

Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Panning
Gold panning, or simply ''panning'', is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome, where gold and other precious metals were extracted from streams and mountainsides using sluices and panning. However, the productivity rate is comparatively smaller compared to other methods such as the rocker box or large extractors, such as those used at the Super Pit gold mine, in Kalgoorlie, Western Australia, which has led to panning being largely replaced in the commercial market. Process Gold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering, and aggressive agita ...

Constitutional Convention (California)
The California Constitutional Conventions were two separate constitutional conventions that took place in California during the nineteenth century which led to the creation of the modern Constitution of California. The first, known as the 1849 Constitutional Convention of Monterey, held in September and October 1849 in advance of California attaining U.S. statehood the following year, adopted the state's original constitution. This document maintains jurisdiction along with the current constitution which was ratified on May 7, 1879, following the 1879 Constitutional Convention of Sacramento. Article 3 Section 2 of the current Constitution references the original boundaries as stated in the 1849 Constitution at Article 7. The result of Progressive mistrust of elected officials, this later constitution took a full year to finalize (March 1878 to March 1879) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boomtown
A boomtown is a community that undergoes sudden and rapid population and economic growth, or that is started from scratch. The growth is normally attributed to the nearby discovery of a precious resource such as gold, silver, or oil, although the term can also be applied to communities growing very rapidly for different reasons, such as a proximity to a major metropolitan area, huge construction project, or attractive climate. First boomtowns Early boomtowns, such as Leeds, Liverpool, and Manchester, experienced a dramatic surge in population and economic activity during the Industrial Revolution at the turn of the 19th century. In pre-industrial England these towns had been relative backwaters, compared to the more important market towns of Bristol, Norwich, and York, but they soon became major urban and industrial centres. Although these boomtowns did not directly owe their sudden growth to the discovery of a local natural resource, the factories were set up there to take ...
