Racial segregation in the United States in the context of "Treaty of Fifth Avenue"

Discrimination is the process of making prejudicial distinctions between people based on the groups, classes, or other categories to which they belong or are perceived to belong, such as race, gender, age, class, religion, disability or sexual orientation. Discrimination typically leads to groups being unfairly treated on the basis of perceived statuses of characteristics, for example ethnic, racial, gender or religious categories. It involves depriving members of one group of opportunities or privileges that are available to members of another group.

Discriminatory traditions, policies, ideas, practices and laws exist in many countries and institutions in all parts of the world, including some, where such discrimination is generally decried. In some places, countervailing measures such as quotas have been used to redress the balance in favor of those who are believed to be current or past victims of discrimination. These attempts have often been met with controversy, and sometimes been called reverse discrimination.

The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States of America from its founding in 1776 until 1865, predominantly in the South. Slavery was found throughout European colonization in the Americas. From 1526, during the early colonial period, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, children were born into slavery, and an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until abolition in 1865, and issues concerning slavery seeped into every aspect of national politics, economics, and social custom. In the decades after the end of Reconstruction in 1877, many of slavery's economic and social functions were continued through segregation, sharecropping, and convict leasing. Involuntary servitude as a punishment for crime remains legal.

By the time of the American Revolutionary War (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. During and immediately following the Revolution, abolitionist laws were passed in most Northern states and a movement developed to abolish slavery. The role of slavery under the United States Constitution (1789) was the most contentious issue during its drafting. The Three-Fifths Clause of the Constitution gave slave states disproportionate political power, while the Fugitive Slave Clause (Article IV, Section 2, Clause 3) provided that, if a slave escaped to another state, the other state could not prevent the return of the slave to the person claiming to be his or her owner. All Northern states had abolished slavery to some degree by 1805, sometimes with completion at a future date, and sometimes with an intermediary status of unpaid indentured servitude.

The civil rights movement was a social movement in the United States from 1954 to 1968 which aimed to abolish legalized racial segregation, discrimination, and disenfranchisement in the country, which most commonly affected African Americans. The movement had origins in the Reconstruction era in the late 19th century, and modern roots in the 1940s. After years of nonviolent protests and civil disobedience campaigns, the civil rights movement achieved many of its legislative goals in the 1960s, during which it secured new protections in federal law for the civil rights of all Americans, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

Following the American Civil War (1861–1865), the three Reconstruction Amendments to the U.S. Constitution abolished slavery and granted citizenship to all African Americans, the majority of whom had recently been enslaved in the southern states. During Reconstruction, African-American men in the South voted and held political office, but after 1877 they were increasingly deprived of civil rights under racist Jim Crow laws (which for example banned interracial marriage, introduced literacy tests for voters, and segregated schools) and were subjected to violence from white supremacists during the nadir of American race relations. African Americans who moved to the North in order to improve their prospects in the Great Migration also faced barriers in employment and housing. Legal racial discrimination was upheld by the Supreme Court in its 1896 decision in Plessy v. Ferguson, which established the doctrine of "separate but equal". The movement for civil rights, led by figures such as W. E. B. Du Bois and Booker T. Washington, achieved few gains until after World War II. In 1948, President Harry S. Truman issued an executive order abolishing discrimination in the armed forces.

The Great Migration, sometimes known as the Great Northward Migration or the Black Migration, was the movement of five million African Americans out of the rural Southern United States to the urban Northeast, Midwest, and West between 1910 and 1970. It was substantially caused by poor economic and social conditions due to prevalent racial segregation and discrimination in the Southern states where Jim Crow laws were upheld. In particular, continued lynchings motivated a portion of the migrants, as African Americans searched for social reprieve. The historic change brought by the migration was amplified because the migrants, for the most part, moved to the then-largest cities in the United States (New York City, Chicago, Los Angeles, San Francisco, Philadelphia, Detroit, Cleveland, and Washington, D.C.) at a time when those cities had a central cultural, social, political, and economic influence over the United States; there, African Americans established culturally influential communities of their own. According to Isabel Wilkerson, despite the losses they felt leaving their homes in the South, and despite the barriers that the migrants faced in their new homes, the migration was an act of individual and collective agency, which changed the course of American history, a "declaration of independence" that was written by their actions.

From the earliest U.S. population statistics in 1780 until 1910, more than 90% of the African-American population lived in the American South, making up the majority of the population in three Southern states, namely Louisiana (until about 1890), South Carolina (until the 1920s), and Mississippi (until the 1930s). But by the end of the Great Migration, just over half of the African-American population lived in the South, while a little less than half lived in the North and West. Moreover, the African-American population had become highly urbanized. In 1900, only one-fifth of African Americans in the South were living in urban areas. By 1960, half of the African Americans in the South lived in urban areas, and by 1970, more than 80% of African Americans nationwide lived in cities. In 1991, Nicholas Lemann wrote:

The Fourteenth Amendment (Amendment XIV) to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. Considered one of the most consequential amendments, it addresses citizenship rights and equal protection under the law at all levels of government. The Fourteenth Amendment was a response to issues affecting freed slaves following the American Civil War, and its enactment was bitterly contested. States of the defeated Confederacy were required to ratify it to regain representation in Congress. The amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark Supreme Court decisions, such as Brown v. Board of Education (1954; prohibiting racial segregation in public schools), Loving v. Virginia (1967; ending interracial marriage bans), Roe v. Wade (1973; recognizing federal right to abortion until overturned in 2022), Bush v. Gore (2000; settling 2000 presidential election), Obergefell v. Hodges (2015; extending right to marry to same-sex couples), and Students for Fair Admissions v. Harvard (2023; prohibiting affirmative action in most college admissions).

The amendment's first section includes the Citizenship Clause, Privileges or Immunities Clause, Due Process Clause, and Equal Protection Clause. The Citizenship Clause broadly defines citizenship, superseding the Supreme Court's decision in Dred Scott v. Sandford (1857), which held that Americans descended from African slaves could not become American citizens. The Privileges or Immunities Clause was interpreted in the Slaughter-House Cases (1873) as preventing states from impeding federal rights, such as the freedom of movement. The Due Process Clause builds on the Fifth Amendment to prohibit all levels of government from depriving people of life, liberty, or property without substantive and procedural due process. Additionally, the Due Process Clause supports the incorporation doctrine, by which portions of the Bill of Rights have been applied to the states. The Equal Protection Clause requires each state to provide equal protection under the law to all people, including non-citizens, within its jurisdiction.

Condoleezza "Condi" Rice (/ˌkɒndəˈliːzə/ KON-də-LEE-zə; born November 14, 1954) is an American diplomat and political scientist who served as the 66th United States secretary of state from 2005 to 2009 and as the 19th U.S. national security advisor from 2001 to 2005. Since 2020, she has served as the 8th director of Stanford University's Hoover Institution. A member of the Republican Party, Rice was the first female African-American secretary of state and the first woman to serve as national security advisor. Until the election of Barack Obama as president in 2008, Rice and her predecessor, Colin Powell, were the highest-ranking African Americans in the history of the federal executive branch (by virtue of the secretary of state standing fourth in the presidential line of succession). At the time of her appointment as Secretary of State, Rice was the highest-ranking woman in the history of the United States to be in the presidential line of succession.

Rice was born in Birmingham, Alabama, and grew up while the South was racially segregated. She obtained her bachelor's degree from the University of Denver and her master's degree from the University of Notre Dame, both in political science. In 1981, she received a PhD from the School of International Studies at the University of Denver. She worked at the State Department under the Carter administration and served on the National Security Council as the Soviet and Eastern Europe affairs advisor to President George H. W. Bush during the dissolution of the Soviet Union and German reunification from 1989 to 1991. Rice later pursued an academic fellowship at Stanford University, where she later served as provost from 1993 to 1999. On December 17, 2000, she joined the George W. Bush administration as national security advisor. In Bush's second term, she succeeded Colin Powell as Secretary of State, thereby becoming the first African-American woman, second African-American after Powell, and second woman after Madeleine Albright to hold this office.

The most common name for the American Civil War in modern American usage is simply "The Civil War". Although rarely used during the war, the term "War Between the States" became widespread afterward in the Southern United States. During and immediately after the war, Northern historians often used the terms "War of the Rebellion" and "Great Rebellion", and the Confederate term was "War for Southern Independence", which regained some currency in the 20th century but has again fallen out of use. The name "Slaveholders' Rebellion" was used by Frederick Douglass and appeared in newspaper articles during that era. "Freedom War" is used to celebrate the war's effect of ending slavery.

During the Jim Crow era of the 1950s, the term "War of Northern Aggression" developed under the Lost Cause of the Confederacy movement by Southern historical revisionists or negationists. This label was coined by segregationists in an effort to equate contemporary efforts to end segregation with 19th-century efforts to abolish slavery.

Presidential elections were held in the United States on November 5, 1968. The Republican ticket of former Vice President Richard Nixon and Maryland governor Spiro Agnew defeated the Democratic ticket of incumbent Vice President Hubert Humphrey and Senator Edmund Muskie and the American Independent Party ticket of former Alabama governor George Wallace and general Curtis LeMay. The election cycle was tumultuous and chaotic, and is often characterized as one of the most violent in American history. It was marked by the assassination of Martin Luther King Jr. in early April and the subsequent 54 days of riots across the US; the assassination of Robert F. Kennedy in early June; and widespread opposition to the Vietnam War across university campuses as well as at the Democratic National Convention, which saw police crackdowns on protesters, reporters, and bystanders.

Incumbent president Lyndon B. Johnson was the early frontrunner for the Democratic nomination, but withdrew from the race after only narrowly winning the New Hampshire primary. Humphrey, Eugene McCarthy, and Robert F. Kennedy emerged as the three major candidates in the Democratic primaries until Kennedy was assassinated. Humphrey, who supported the Vietnam War, defeated the anti-war McCarthy to win the Democratic nomination, sparking protests. Humphrey's promise to continue the Johnson administration's war on poverty and support for the civil rights movement eroded his support in the South, prompting a third-party run by Wallace that campaigned for racial segregation on the basis of "states' rights." Wallace attracted socially conservative voters throughout the South (including Southern Democrats and former Barry Goldwater supporters), as well as white working-class voters in the North and Midwest through his economic populism and anti-establishment rhetoric.
