The term Fourth Estate or fourth power refers to the press and news media in their explicit capacity, beyond the reporting of news, of wielding influence in politics.[1] The derivation of the term arises from the traditional European concept of the three estates of the realm: the clergy, the nobility, and the commoners.
The equivalent term "fourth power" is somewhat uncommon in English, but it is used in many European languages, including German (Vierte Gewalt), Italian (quarto potere), Spanish (Cuarto poder), French (Quatrième pouvoir), Swedish (tredje statsmakten [Third Estate]), Polish (Czwarta Władza), and Russian (четвёртая власть) to refer to a government's separation of powers into legislative, executive, and judicial branches.
The expression has also been applied to lawyers, to the British Queen Consort (acting as a free agent independent of her husband), and to the proletariat. But, generally, the term "Fourth Estate" refers to the press and media, emphasizing its role in monitoring and influencing the other branches of government and society.
A Fifth Estate, while not recognized in the same way as the first four, includes bloggers, social media influencers, and other online platforms that can influence public discourse and politics independently of traditional media.[2][3][4]
