From the end of the 19th century until the present, journalists have created associations, trade unions, clubs, and major international networks to organize workers, defend their rights, set out their duties, establish rules of good conduct, and structure their professional journalistic skills. These journalistic organizations are central actors in the history of the professionalization of journalistic groups around the world. They have enabled journalists to make their demands public, exchange views with journalists from other countries, and sometimes even promote and achieve legal recognition of their profession. In general terms, they have provided journalists with fora to discuss their working conditions, their profession, and the social role of the media and journalism. In this way, they have helped to structure not only discourses and practices, but also networks of solidarity at both national and international levels. These organizations can exist in different arenas: within media companies, at the national level, or internationally. And, despite their variety over time, they have often pursued similar objectives: protect journalists’ pay and employment conditions and status; conceive strategies to maintain a certain form of autonomy in authoritarian political contexts; nourish international networking ambitions that have made it possible to disseminate ways of doing and thinking journalism; and finally generate a set of actions that aims to defend the ethics of journalism, the quality of news, and the lives of journalists.
