Propaganda is a concerted set of messages aimed at influencing the opinions or behaviors of large numbers of people. As opposed to impartially providing information, propaganda in its most basic sense presents information in order to influence its audience. Propaganda often presents facts selectively (thus lying by omission) to encourage a particular synthesis, or gives loaded messages in order to produce an emotional rather than rational response to the information presented. The desired result is a change of the cognitive narrative of the subject in the target audience to further a political agenda.

Etymology

The word originates from the Latin name Congregatio de Propaganda Fide ("Congregation for the Spreading of the Faith") of a congregation founded by Pope Gregory XV in 1622. This department of the pontifical administration was charged with the spread of Catholicism and with the regulation of ecclesiastical affairs in mission territory.

The Latin adjective propaganda, which is a form of the gerundive of the verb propago (from pro- "forth" + *pag-, root of pangere "to fasten"), means "that which is to be spread" and does not carry a connotation of information, misleading or otherwise. The modern sense dates from World War I, when the term evolved to be mainly associated with politics.

Types

Propaganda was often used to influence opinions and beliefs on religious issues, particularly during the split between the Catholic Church and the Protestants. Propaganda has become more common in political contexts, in particular to refer to certain efforts sponsored by governments, political groups, but also often covert interests. In the early 20th century, propaganda was examplified in the form of party slogans. Also in the early 20th century the term propaganda was also used by the founders of the nascent public relations industry to describe their activities. This usage died out around the time of World War II, as the industry started to avoid the word, given the pejorative connotation it had acquired.

Literally translated from the Latin gerundive as "things which must be disseminated", in some cultures the term is neutral or even positive, while in others the term has acquired a strong negative connotation. The connotations of the term "propaganda" can also vary over time. For example, in Portuguese and some Spanish language speaking countries, particularly in the Southern Cone, the word "propaganda" usually refers to the most common manipulative media — "advertising".
