Antebellum expansion

The Antebellum Age was the period of increasing sectionalism that led up to the American Civil War. The Antebellum Age was a time of great transition because of the industrial revolution in America. It also was a time of growth in slavery in the American South. In a sense, the Antebellum Period is often considered to have begun with the Kansas-Nebraska Act of 1854, though it is stipulated to extend back as early as 1812.

American westward expansion is idealized in Emanuel Leutze's famous painting Westward the Course of Empire Takes its Way (1861).

"Manifest Destiny" was the territorial expansion of the United States from to 1848. Manifest Destiny incorporated the belief that the United States was destined, to expand across the North American continent, from the Atlantic seaboard to the Pacific Ocean. During this time, the United States expanded to the Pacific Ocean—"from sea to shining sea"—largely defining the borders of the contiguous United States as they are today.

Civil War and Reconstruction

Main articles: American Civil War and Reconstruction era of the United States

The American Civil War came when seven (later eleven) Southern slave states declared their secession from the U.S. and formed the Confederate States of America (the Confederacy). Led by Jefferson Davis, they fought against the U.S. federal government (the Union) under President Abraham Lincoln, which was supported by all the free states and the five border slave states in the north.
Northern leaders agreed that victory would require more than the end of fighting. Secession and Confederate nationalism had to be totally repudiated and all forms of slavery or quasi-slavery had to be eliminated. Lincoln proved effective in mobilizing support for the war goals, raising large armies and supplying them, avoiding foreign interference, and making the end of slavery a war goal. The Confederacy had a larger area than it could defend, and it failed to keep its ports open and its rivers clear. The North kept up the pressure as the South could barely feed and clothe its soldiers. Its soldiers, especially those in the East under the command of General Robert E. Lee proved highly resourceful until they finally were overwhelmed by Generals Ulysses S. Grant and William T. Sherman in 1864-65, The Reconstruction Era (1863–77) began with the Emancipation proclamation in 1863, and included freedom, full citizenship and the vote for the Southern blacks. It was followed by a reaction that left the blacks in a second class status legally, politically, socially and economically until the 1960s.

The Gilded Age and legacy

Main article: Gilded Age

During the Gilded Age, there was substantial growth in population in the United States and extravagant displays of wealth and excess of America's upper-class during the post-Civil War and post-Reconstruction era, in the late 19th century. The wealth polarization derived primarily from industrial and population expansion. The businessmen of the Second Industrial Revolution created industrial towns and cities in the Northeast with new factories, and contributed to the creation of an ethnically diverse industrial working class which produced the wealth owned by rising super-rich industrialists and financiers called the "robber barons". An example is the company of John D. Rockefeller, who was an important figure in shaping the new oil industry. Using highly effective tactics and aggressive practices, later widely criticized, Standard Oil absorbed or destroyed most of its competition.
The creation of a modern industrial economy took place. With the creation of a transportation and communication infrastructure, the corporation became the dominant form of business organization and a managerial revolution transformed business operations. In 1890, Congress passed the Sherman Antitrust Act—the source of all American anti-monopoly laws. The law forbade every contract, scheme, deal, or conspiracy to restrain trade, though the phrase "restraint of trade" remained subjective. By the beginning of the 20th century, per capita income and industrial production in the United States exceeded that of any other country except Britain. Long hours and hazardous working conditions led many workers to attempt to form labor unions despite strong opposition from industrialists and the courts. But the courts did protect the marketplace, declaring the Standard Oil group to be an "unreasonable" monopoly under the Sherman Antitrust Act in 1911. It ordered Standard to break up into 34 independent companies with different boards of directors.^[71]

Science and Philosophy

Replacing the classical physics in use since the end of the scientific revolution, modern physics arose in the early 20th century with the advent of quantum physics,^[72] substituting mathematical studies for experimental studies and examining equations to build a theoretical structure.^[73] The old quantum theory was a collection of results which predate modern quantum mechanics, but were never complete or self-consistent.^[74] The collection of heuristic prescriptions for quantum mechanics were the first corrections to classical mechanics.^[74][75] Outside the realm of quantum physics, the various aether theories in classical physics, which supposed a "fifth element" such as the Luminiferous aether,^[76] were nullified by the Michelson-Morley experiment—an attempt to detect the motion of earth through the aether. In biology, Darwinism gained acceptance, promoting the concept of adaptation in the theory of natural selection. The fields of geology, astronomy and psychology also made strides and gained new insights. In medicine, there were advances in medical theory and treatments.

The assertions of Chinese philosophy^[77] began to integrate concepts of Western philosophy, as steps toward modernization. By the time of the Xinhai Revolution in 1911, there were many calls, such as the May Fourth Movement, to completely abolish the old imperial institutions and practices of China. There were attempts to incorporate democracy, republicanism, and industrialism into Chinese philosophy, notably by Sun Yat-Sen (Sūn yì xiān, in one Mandarin form of the name) at the beginning of the 20th century. Mao Zedong (Máo zé dōng) added Marxist-Leninist thought. When the Communist Party of China took over power, previous schools of thought, excepting notably Legalism, were denounced as backward, and later even purged during the Cultural Revolution.
Starting one-hundred years before the 20th century, the enlightenment spiritual philosophy was challenged in various quarters around the 1900s.^{[78][79][80][81][82][83]} Developed from earlier secular traditions,^[84] modern Humanist ethical philosophies affirmed the dignity and worth of all people, based on the ability to determine right and wrong by appealing to universal human qualities, particularly rationality, without resorting to the supernatural or alleged divine authority from religious texts.^[85][86] For liberal humanists such as Rousseau and Kant, the universal law of reason guided the way toward total emancipation from any kind of tyranny. These ideas were challenged, for example by the young Karl Marx, who criticized the project of political emancipation (embodied in the form of human rights), asserting it to be symptomatic of the very dehumanization it was supposed to oppose. For Friedrich Nietzsche, humanism was nothing more than a secular version of theism. In his Genealogy of Morals, he argues that human rights exist as a means for the weak to collectively constrain the strong. On this view, such rights do not facilitate emancipation of life, but rather deny it. In the 20th century, the notion that human beings are rationally autonomous was challenged by the concept that humans were driven by unconscious irrational desires.

Notable persons

Sigmund Freud is renowned for his redefinition of sexual desire as the primary motivational energy of human life, as well as his therapeutic techniques, including the use of free association, his theory of transference in the therapeutic relationship, and the interpretation of dreams as sources of insight into unconscious desires.
Albert Einstein is known for his theories of special relativity and general relativity. He also made important contributions to statistical mechanics, especially his mathematical treatment of Brownian motion, his resolution of the paradox of specific heats, and his connection of fluctuations and dissipation. Despite his reservations about its interpretation, Einstein also made contributions to quantum mechanics and, indirectly, quantum field theory, primarily through his theoretical studies of the photon.

Social Darwinism

At the end of the 19th century, Social Darwinism was promoted and included the various ideologies based on a concept that competition among all individuals, groups, nations, or ideas was a "natural" framework for social evolution in human societies. In this view, society's advancement is dependent on the "survival of the fittest", the term was in fact coined by Herbert Spencer and referred to in "The Gospel of Wealth" written by Andrew Carnegie.

Marxist society

The Communist Manifesto

Karl Marx summarized his approach to history and politics in the opening line of the first chapter of The Communist Manifesto (1848). He wrote:

The history of all hitherto existing society is the history of class struggles.^[87]

The Manifesto went through a number of editions from 1872 to 1890; notable new prefaces were written by Marx and Engels for the 1872 German edition, the 1882 Russian edition, the 1883 German edition, and the 1888 English edition. In general, Marxism identified five (and one transitional) successive stages of development in Western Europe.^[88]

1. Primitive Communism: as seen in cooperative tribal societies.
2. Slave Society: which develops when the tribe becomes a city-state. Aristocracy is born.
3. Feudalism: aristocracy is the ruling class. Merchants develop into capitalists.
4. Capitalism: capitalists are the ruling class, who create and employ the true working class.
5. Dictatorship of the proletariat: workers gain class consciousness, overthrow the capitalists and take control over the state.
6. Communism: a classless and stateless society.
