1. Civil and political rights are a class of rights that protect individuals' freedom from infringement by governments and private organizations, and ensure one's ability to participate in the civil and political life of the state without discrimination or repression. Civil rights include the ensuring of peoples' physical and mental integrity, life and safety; protection from discrimination on grounds such as race, gender, national origin, colour, sexual orientation, ethnicity, religion, or disability; [ and individual rights such as privacy, the freedoms of thought and conscience, speech and expression, religion, the press, assembly and movement. Political rights include natural justice (procedural fairness) in law, such as the rights of the accused, including the right to a fair trial; due process; the right to seek redress or a legal remedy; and rights of participation in civil society and politics such as freedom of association, the right to assemble, the right to petition, the right of self-defense, and the right to vote. Civil and political rights form the original and main part of international human rights. They comprise the first portion of the 1948 Universal Declaration of Human Rights (with economic, social and cultural rights comprising the second portion). The theory of three generations of human rights considers this group of rights to be "first-generation rights", and the theory of negative and positive rights considers them to be generally negative rights

2. Slavery in the United States was the legal institution of chattel slavery that existed in the United States of America in the 18th and 19th centuries. Slavery had been practiced in British North America from early colonial days, and was recognized in the thirteen Colonies at the time of the Declaration of Independence in 1776. When the United States was founded, even though some free persons of colour were present, the status of slave was largely limited to those of African descent, creating a system and legacy in which race played an influential role. After the Revolutionary War, abolitionist laws and sentiment gradually spread in the Northern states, while the rapid expansion of the cotton industry from 1800 led to the Southern states strongly identifying with slavery, and attempting to extend it into the new Western territories. The United States was polarized by slavery into slave and free states along the Mason-Dixon Line, which separated Maryland (slave) and Pennsylvania45

3. Racism consists of both prejudice and discrimination based in social perceptions of biological differences between peoples. It often takes the form of social actions, practices or beliefs, or political systems that consider different races to be ranked as inherently superior or inferior to each other, based on presumed shared inheritable traits, abilities, or qualities. It may also hold that members of different races should be treated differently. Some consider any assumption that a person's behaviour might be influenced by their racial categorization is inherently racist, regardless of whether the action is intentionally harmful or pejorative, because stereotyping necessarily subordinates individual identity to group identity. In sociology and psychology, some definitions only include consciously malignant forms of discrimination
