The 2000–2014 research survey of the Social Sciences Citation Index ranks him as the world's fifth most-cited social science scholar, and the foremost-cited communication scholar.

In 2012, Castells was awarded the Holberg Prize, for having "shaped our understanding of the political dynamics of urban and global economies in the network society." In 2013, he was awarded the Balzan Prize for Sociology for "his wide-ranging and imaginative thinking through of the implications of the great technological changes of our time."

In January 2020, he was appointed minister of universities in the second government of Pedro Sánchez in Spain, a position he held until his resignation in December 2021.

Biography

Early life

Manuel Castells was born on February 9, 1942, in the city of Hellín, in the La Mancha region, under the Spanish State. His parents, Fernando Castells Adriaensens and Josefina Olivan Escartin were both civil servants. He also has a younger sister named Irene. He grew up in Madrid, Cartagena, and Valencia, where his father, a financial inspector, was posted to.

Politics was a part of Castells' life from an early age. He notes:

My parents were very good parents. It was a conservative family — very strongly conservative family. But I would say that the main thing that shaped my character besides my parents was the fact that I grew up in fascist Spain. It's difficult for people of the younger generation to realize what that means, even for the Spanish younger generation. You had actually to resist the whole environment, and to be yourself, you had to fight and to politicize yourself from the age of fifteen or sixteen.Harry Kreisler, Manuel Castells, Conversations with History: Manuel Castells (video interview, 9 May 2001), Berkeley, CA: University of California Television (UCTV), 2001, 1min26sec.

Castells' engagement is evident in his early opposition to Francisco Franco’s semi-fascist regime. His father initially fought in its favor as a member of the Falange Party. Castells' father eventually abandoned this mentality, as he was no longer pleased with Franco's rule.

Early education and activism Castells completed his secondary education in Barcelona two years ahead of time in 1958, after which he studied law and economics at the University of Barcelona. As a student, he took an interest in literature and theatre. Government censorship of plays and crackdown on student journals moved him to join the broad anti-Franco movement opposition group Workers' Front of Catalonia in 1960, and he read Marxist and anarchist theory alongside his activism. In May 1962, Castells participated in solidarity action with the miners' strike in the Asturias region.

During the repression that followed, he escaped to France, interrupting his studies in Barcelona. He successfully claimed political asylum with the help of a fellow Spanish opposition member and settled in Paris. In Paris, he completed his first degree at the Sorbonne in 1964 and earned a doctorate in sociology from the University of Paris in 1967. He was supervised by the sociologist Alain Touraine at the Nanterre Faculty of Arts and Humanities and his thesis committee also included sociologist Henri Lefebvre and geographer .

Catalan identity

Castells identifies as Catalan largely because of his connection to Barcelona, which is recognized as the center of the Catalan movement for independence. He spent a large portion of his adolescence there, completing his secondary and beginning his college education at the University of Barcelona. Castells also traces his paternal lineage to the city. This aspect of Castells' identity is related to his resistance to Franco's oppressive regime. The Catalan language was not taught at school under Franco, and Castells' family, being from a Spanish speaking region of Spain, therefore did not speak it. However, he took the initiative to teach the language to himself while at University, which he states has helped him feel more connected to his Catalan identity. Castells is a Catalan nationalist, but not a separatist. He has expressed support for the Catalan Socialist Party.Castells, Manuel, and Martin Ince. 2003. “Manuel Castells: Life and Work.” Pp.8 in Conversations with Manuel Castells. Cambridge: Polity Press.

Academic career

Castells was appointed research assistant by his supervisor Alain Touraine at the Nanterre Faculty in 1966. From 1967 onwards, he worked as an instructor in several Parisian universities. He first taught at Nanterre, where Daniel Cohn-Bendit was among his students. He saw his contract there terminated as a result of the 1968 student protests. He spent a part of the period between 1968 and 1972 in Santiago, Chile, where he held visiting appointments at the University of Chile, working with the dependency theorists Fernando Henrique Cardoso and Enzo Faletto, and at the Pontifical Catholic University of Chile's Ford Foundation arm, the Interdisciplinary Committee for Urban Development (Centro Interdisciplinario de Desarrollo Urbano, CIDU) (a position he retained as late as April 1973). He taught at the École des Hautes Études en Sciences Sociales in Paris from 1970 to 1979.

In 1979, Castells joined the University of California, Berkeley, as a professor of sociology and a professor of city and regional planning.

In 2001, he was a research professor at the Open University of Catalonia in Barcelona. In 2003, he was appointed the inaugural Wallis Annenberg Chair of Communication and Technology at the University of Southern California's (USC) Annenberg School for Communication. He is a founding member of the USC Center on Public Diplomacy, a senior member of the diplomacy center's Faculty Advisory Council, and a member of the Annenberg Research Network on International Communication. He held the chair of network society at 's Collège d’Études Mondiales in Paris (closed in 2020).

Castells lives between Spain and the United States. In 2008, he was appointed to the governing board of the European Institute of Innovation and Technology. He served as the minister of universities in Spain from January 2020 to December 2021.

Theoretical contributions

The sociological work of Manuel Castells synthesizes empirical research literature with combinations of urban sociology, organization studies, internet studies, social movements, sociology of culture, and political economy. About the origins of the network society, he posits that changes to the network form of enterprise predate the electronic internet technologies (usually) associated with network organization forms (cf. Organization theory (Castells)).

Information Age

Castells' most well-known work is a trilogy of books, entitled The Information Age: Economy, Society and Culture. Overall, it comprehends three sociological dimensions—production, power, and experience—stressing that the organization of the economy, of the state and its institutions, and the ways that people create meaning in their lives through collective action, are irreducible sources of social dynamics—that must be understood as both discrete and inter-related entities.

The Information Age trilogy is his précis: "Our societies are increasingly structured around the bipolar opposition of the Net (social network) and the Self";Castells, The Rise of the Network Society (1996) p. 3 the "Social network" denotes the network organizations replacing vertically integrated hierarchies as the dominant form of social organization, the Self denotes the practices a person uses in reaffirming social identity and meaning in a continually changing cultural landscape. In other words, Castells' theory of the Information Age explores the dissonance between “universal, digital language,” and individual, even local identities. Our physical selves exist in different places and experience different cultures, but the mind has essentially migrated into the world of the internet and the television. They exist in a “global space of instant information".Mann, Douglas. 2008. “Postmodernism: Political Economy and Communications.” Pp. 265–275 in Understanding Society: A Survey of Modern Social Theory. Canada: Oxford University Press.

Castells maintains that the Information Age can "unleash the power of the mind", which would dramatically increase the productivity of individuals and lead to greater leisure, allowing individuals to achieve "greater spiritual depth and more environmental consciousness". Such change would be positive, he argues, in that it would cause resource consumption to decrease.

Castells also became an established cybernetic culture theoretician with his Internet development analysis stressing the roles of the state (military and academic), social movements (computer hackers and social activists), and business, in shaping the economic infrastructure according to their (conflicting) interests.

Informationalism

Castells' concepts of The Information Age, The Age of Consumption, and The Network Society are all perspectives attempting to describe modern life as it is known in the present and to depict the future of society. As Castells suggests, contemporary society may be described as "replacing the antiquated metaphor of the machine with that of the network". Put simply, this quote exemplifies Castells' concept of “Informationalism.” He asserts that from the 1970s to the present day, informational technology has allowed large businesses, organizations, and social structures in general to form global networks. The world is growing away from industrialism, which is focused on economic growth. Informationalism strives to develop knowledge and create massive networks. This theory is, of course, related to the growth of capitalism. As networks grow larger, the state gradually plays a smaller role in the capitalist system. Common systems of information have begun to replace it. They act as a connector between networks that may very likely be on opposite sides of the globe.Stevenson, Nick. 2003. “Manuel Castells.” Pp.92 in Key Contemporary Social Theorists, edited by Anthony Elliott and Larry Ray. Blackwell Publishers Ltd.

This development does not come without some level of exclusion. For certain areas of the globe that are not as connected with mainstream society and massive international networks, it is becoming increasingly difficult to keep pace with the expansion of capitalism. Excluded communities respond by developing their own systems, which are often based in illicit economic activity.Stevenson, Nick. 2003. “Manuel Castells.” Pp.92–93 in Key Contemporary Social Theorists, edited by Anthony Elliott and Larry Ray. Blackwell Publishers Ltd. These illicit economic activities illustrate another of Castells' points, that resistance to globalization is a result of the development of the information age. He explains this using an example:
