The newspaper A Batalha (1919 — present) is a workers' newspaper with anarcho-syndicalist tendencies founded on 23 February 1919, the same year as the Portuguese General Confederation of Labour (CGT), for which it would be the spokesperson. Its first editor was the typographer and journalist Alexandre Vieira. As a daily newspaper, it achieved the third largest circulation in Portugal. It ceased publication as a daily periodic on 26 May 1927, when its premises were destroyed by the police. It was re-published numerous times, with different frequency, and was relaunched in 2017 by a team made up of old and new militants.

When it first appeared, A Batalha was so successful that it made repressive action against the new newspaper difficult. A Batalha was a daily newspaper - something unthinkable nowdays, and became the third best-selling newspaper in Lisbon, after O Século and Diário de Notícias. It had a great advantage: when there was a typographers' strike, it was the only newspaper in circulation. In addition to its political content, its success was due to the literary talent of its contributors, such as Ferreira de Castro, author of The Jungle, among others, and who was the most translated Portuguese writer in his time.
