O Inimigo do Rei was an anarchist newspaper that circulated in Bahia during the military dictatorship in Brazil.

[1] According to Bernardo Kucinski, "in contrast to the complacency of the mainstream press towards the military dictatorship, alternative newspapers vehemently demanded the restoration of democracy and respect for human rights and criticized the economic model.

"[2] In several of its editions, workers who collaborated with the newspaper published articles that went against what appeared to be the rigging of unions by the political parties.

The article informed that some groups were organizing for a possible reconstruction of the old confederation, with all its principles and doctrines.

It was also the spokesperson for several social movements that did not find space in the mainstream press or even in the alternative press, such as drug users, homosexuals, the most radical black and feminist movements, militant atheists, anti-asylum activists, environmentalists and so many others who had their topics covered in the newspaper,[3][4] which gave it repercussion not only in Brazil but also in the US, Portugal, Spain, Switzerland, Sweden, Italy, Austria, Germany, Argentina, among other countries with which the editors ended up keeping in touch.
