Resource mobilization, a dominant theoretical approach to the study of social movements for
many decades, points to social movement organizations (SMOs) as a focal point for efforts to understand
the variations in both the impact and fate of social movements. SMOs, like other types of political
organizations, are expected to repr esent members’ common preferences for some specified social change,
acting to bring about such change through influence on formal political decision-making, or on general
behaviors of the members of a polity, or on both. In this context, the classic analysis offered by Robert
Michels ([1911] 1962) of typical evolutionary processes in the governance of political organizations, and
the impact of such processes on organizations’ goals, is very relevant to scholars of social movements.
Early studies of social movements often drew heavily on Michels’ work (e.g., Messinger, 1955; Sills,
1957; Zald and Denton, 1963), documenting and fleshing out the nature of the evolutionary processes he
posited, and the transformational consequences for social movements. Concern with movement
transformation has been less dominant in contemporary work, despite a lack of evidence that such
processes are any less operative in current movement organizations. Below, the key processes involved
in what Michels’ referred to as the “iron law of oligarchy” are sketched, followed by a brief discussion of
some of the implications of this analysis for social movement researchers.
Drawing on his own disillusioning experiences as a member and supporter of a socially
liberal political party in early 20th
century Germany, Michels described a number of conditions
and processes that inevitably impelled (in his view) even the most democratically-committed
organizations to become divided into a set of elites, or oligarchs, with their own set of distinctive
interests in the organization, and the rest of the membership, whose labor and resources are
exploited by the elites. The first condition precipitating the drift to such an oligarchical system is,
ironically, success in recruiting new members to the organization’s cause. As organizations
grow, the ability of members to participate equally in organizational decisions becomes
progressively more difficult, both because it is hard to find a place and time for all members to
assemble and because decision-making is significantly slowed – not infrequently to a standstill –
as the number of decision-makers increases. The usual response is to such problems is
de legation of responsibility to a relatively small subset of members for formulating and
recommending lines of action. Although members may attempt to maintain democratic control
by demanding extensive explanations for leaders’ proposals and maintaining ultimate voting
rights on these, a number of forces militate against such control.
First, as a very large body of research on organizations has documented, increases in
organizational size lead to increases in complexity – the creation of separate, specialized
positions and units to carry out different tasks – as well as to increases in rules and formal
processes. Thus, effective administration requires both hard-to-gain, specialized knowledge of
these aspects of the organization (Michels referred to this as “administrative secrets”), and what
are often scarce organizing talents, such as the ability to manage interpersonal relations and to
conduct logistical planni ng. This limits the ability of rank-and-file members to challenge
leaders’ recommendations or decisions, and to replace them; thus, power increasingly inheres in
the leadership.
Moreover, once ensconced, leaders are likely to acquire vested interests in maintaining
their po sitions in the organization. As with complexity and formalization, increasing
organizational size also typically leads to the creation of full-time administrative positions; thus,
office-holding becomes a means through which incumbents make their livelihood. Michels
argued that this, in turn, makes it likely that the leaders will ultimately recognize their common
interests in maintaining their positions within the organization, and develop a sense of solidarity
with one another (becoming, in Marxian terminology, like a classe fur sich). As such, they are
inclined to act cohesively in fending off criticisms and warding off displacement efforts by the
membership. If serious challenges are not readily suppressed, the leaders may resort to
cooptation of individual rank-and-file members, thus effectively hobbling lower-level resistance.
Because their continued position also depends on the survival of the organizations, Michels also
suggested that leaders of once-radical protest organizations are likely to guide them in an
increasingly conservative direction, to minimize chances of state or general social sanctioning,
and the ultimate disbanding of the organization. Given these commonplace evolut ionary
developments in organizations, Michel was led to the famous, pessimistic conclusion ([1911]
1962: 365), “He who says organization, says oligarchy.”
As noted at the outset, Michels’ analysis has provided the basis for a number of classic
studies documenting the evolution and transformation of social movements; it has also generated
efforts to define conditions that may mitigate the postulated evolutionary processes (see Lipset,
Trow and Coleman, 1956; Rothschild-Whitt, 1979). (For an extended discussion of Michels’
arguments and the implications for studies of hierarchical economic organizations, see Tolbert
and Hiatt, 2009). It has been revisited, although somewhat less directly, in research and debates
on the advantages and disadvantages of the use of professional employees by social movement
organizations (e.g., Jenkins, 1977; McAdam, 1983; Staggenborg, 1988). A key implication of
Michels’ work for social movement researchers, however, has been given only limited attention:
the need to understand sources of variations in governance arrangements, and their impact on
SMO decision-making processes and outcomes. Some progress has begun to be made on this
front (e.g., Carmin and Balser, 2002; Jasper, 2004; Osterman, 2006), and recent studies have
explicitly called for more work (Minkoff and McCarthy, 2005), but it remains an important,
largely unexplored legacy of Michels
