Terrorism, in its broadest sense, is the use of criminal violence to provoke a state of terror, mostly with the intention to achieve political or religious aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants. The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but became widely used internationally and gained worldwide attention in the 1970s during the Troubles in Northern Ireland, the Basque conflict, and the Israeli–Palestinian conflict. The increased use of suicide attacks from the 1980s onwards was typified by the 2001 September 11 attacks in the United States.
A lone wolf attack, or lone actor attack, is a particular kind of mass murder, committed in a public setting by an individual who plans and commits the act on their own. In the United States, such attacks are usually committed with firearms. In other countries, knives are sometimes used to commit mass stabbings. Although definitions vary, most databases require a minimum of four victims for the event to be considered a mass murder.

Domestic terrorism in the United States consists of incidents which are confirmed to be domestic terrorist acts. These attacks are considered domestic because they occurred within the United States and they were carried out by U.S. citizens and/or U.S. permanent residents.

Right-wing terrorism, hard right terrorism, extreme right terrorism or far-right terrorism is terrorism that is motivated by a variety of different right-wing and far-right ideologies, most prominently, it is motivated by neo-Nazism, anti-communism, neo-fascism, ecofascism, ethnonationalism, religious nationalism, and anti-government patriot/sovereign citizen beliefs, and occasionally, it is motivated by opposition to abortion, tax resistance, and homophobia. Modern right-wing terrorism largely emerged in Western Europe in the 1970s, and after the Revolutions of 1989 and the dissolution of the Soviet Union in 1991, it emerged in Eastern Europe and Russia.
Radicalization is the process by which an individual or a group comes to adopt increasingly radical views in opposition to a political, social, or religious status quo. The ideas of society at large shape the outcomes of radicalization; for example, radical movements can originate from a broad social consensus against progressive changes in society or from a broad desire for change in society. Radicalization can result in both violent and nonviolent action – academic literature focuses on radicalization into violent extremism (RVE) or radicalisation leading to acts of terrorism. Multiple separate pathways can promote the process of radicalization, which can be independent but are usually mutually reinforcing.

Jihadist extremism in the United States refers to Islamic extremism occurring within the United States. Islamic extremism is an adherence to a fundamentalist interpretation of Islam, potentially including the promotion of violence to achieve political goals. In the aftermath of the September 11, 2001 terror attacks, Islamic extremism became a prioritized national security concern of the United States government and a focus of many subsidiary security and law enforcement entities. Initially, the focus of concern was on foreign terrorist groups, particularly Al-Qaeda, but in the course of the years since the September 11th attacks, the focus has shifted more towards Islamic extremism within the United States. Although the number of American citizens or long-term residents involved in extremist activity is small, it is a national security concern.

Domestic terrorism or homegrown terrorism is a form of terrorism in which victims "within a country are targeted by a perpetrator with the same citizenship" as the victims. There are many definitions of terrorism, and none of them are universally accepted. The United States Department of State defined terrorism in 2003 as "premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents, usually intended to influence an audience." However, the U.S. government cannot charge someone with domestic terrorism because no such criminal law exists.
