A conspiracy theory is an explanation for an event or situation that asserts the existence of a conspiracy by powerful and sinister groups, often political in motivation, when other explanations are more probable. The term generally has a negative connotation, implying that the appeal of a conspiracy theory is based in prejudice, emotional conviction, or insufficient evidence. A conspiracy theory is distinct from a conspiracy; it refers to a hypothesized conspiracy with specific characteristics, including but not limited to opposition to the mainstream consensus among those who are qualified to evaluate its accuracy, such as scientists or historians.
A conspiracy, also known as a plot, is a secret plan or agreement between people for an unlawful or harmful purpose, such as murder, treason, or corruption, especially with political motivation, while keeping their agreement secret from the public or from other people affected by it. In a political sense, conspiracy refers to a group of people united in the goal of usurping, altering or overthrowing an established political power. Depending on the circumstances, a conspiracy may also be a crime, or a civil wrong. The term generally connotes, or implies, wrongdoing or illegality on the part of the conspirators, as it is commonly believed that people would not need to conspire to engage in activities that were lawful and ethical, or to which no one would object.
UFO conspiracy theories are a subset of conspiracy theories which argue that various governments and politicians globally, in particular the United States government, are suppressing evidence that unidentified flying objects are controlled by a non-human intelligence or built using alien technology.

The New World Order (NWO) is a term used in several conspiracy theories which hypothesize a secretly emerging totalitarian world government. The common theme in conspiracy theories about a New World Order is that a secretive power elite with a globalist agenda is conspiring to eventually achieve world domination and rule the world through an authoritarian one-world government—which will replace sovereign nation-states—and an all-encompassing propaganda whose ideology hails the establishment of the New World Order as the culmination of history's progress. Many influential historical and contemporary figures have therefore been alleged to be part of a cabal that operates through many front organizations to orchestrate significant political and financial events, ranging from causing systemic crises to pushing through controversial policies, at both national and international levels, as steps in an ongoing plot to achieve world domination.
