Academic research
Mann's main work is The Sources of Social Power (four volumes). The first two volumes of The Sources of Social Power were published in 1986 and 1993. The last two volumes were published in 2012 and 2013 respectively. He also published several works on the twentieth and early twenty-first centuries. These include Incoherent Empire, in which he attacks the United States' 'War on Terror' as a clumsy experiment in neo-imperialism. Two of his works, Fascists and The Dark Side of Democracy, focus on fascism and ethnic cleansing. His last work, On Wars, covers the experience of war around the world throughout history. Mann's work has been subject of several books, including John Hall and Ralph Schroder's The Anatomy of Power: Social Theory of Michael Mann (2006) and Ralph Schroder's Global Powers: Michael Mann's Anatomy of 20th Century and Beyond (2016). Social theory

One of Mann’s main ideas is his IEMP model, where IEMP stands for distinct ideological, economic, military, and political sources of power. The four components of the IEMP model are defined as follows:
 Ideological power is seen as deriving from “the human need to find ultimate meaning in life, to share norms and values, and to participate in aesthetic and ritual practices with others.” 
 Economic power is grounded in “the human need to extract, transform, distribute, and consume the products of nature.” 
 Military power pertains to “the social organization of concentrated and lethal violence.”
 Political power is “the centralized and territorial regulation of social life.”

In this model, counter to Marx, none of these sources of power is seen as determinative in the last instance. Counter to Weber, Mann treats military power as distinct from political power. In his theory of the state, Mann notes that “modern states formally monopolize the means of military violence” but that does “not end the autonomy of military power organization.”  Mann provides a definition of the state in terms of four attributes:

 "(1) The state is a differentiated set of institutions and personnel
 (2) embodying centrality, in the sense that political relations radiate to and from a center, to cover a
 (3) territorially demarcated area over which it exercises
 (4) some degree of authoritative, binding rule making, backed up by some organized physical force." Mann also suggests that Weber confuses two conceptions of state strength, those related to distributive despotic power and collective infrastructural power. For Mann despotic power refers to “the distributive power of state elites over civil society,” while infrastructural power is “the institutional capacity of a state, despotic or not, to penetrate its territories and logistically implement decisions.”

Comparative history
Mann’s main contribution to comparative history is his four-volume The Sources of Social Power. Volume I (1986) goes from the earliest recorded history to 1760. Volume II (1993) covers the long-nineteenth century. Volumes III and IV (2012, 2013) analyze the twentieth century. Wars
Mann’s (2023) On Wars is a work that focuses on military power and its main mechanism, war. It covers wars in Rome, imperial China, the Mongols, Japan, medieval and modern Europe, pre-Columbian and Latin America, the world wars, and recent American and Middle Eastern wars. Reception of Mann’s ideas

Mann has been called “one of the premier macro-historical sociologists” and “the Max Weber of our time.”

Gianfranco Poggi questioned Mann’s conceptual decision to treat military power as a distinct source of power and defended the classic distinction between economic, political and ideological power. David D. Laitin challenged two thesis in Mann’s The Dark Side of Democracy: Explaining Ethnic Cleansing: (1) that democracy and murderous ethnic cleansing are systematically associated, and (2) that genocide as a modern form of state murder is worse than other forms of mass murder. A special issue of Studies in Comparative International Development focuses on Mann’s concept of state infrastructural power. Mann has responded at length to various critiques. Selected publications
