The chapter presents the analytical approach developed in this book, conceptualized as a ‘structural field of contention approach.’ We first discuss the benefits of existing field approaches in the study of social mobilization, as well as their limitations. Deriving inspiration from Nick Crossley’s notion of social movements as ‘fields of contention,’ we then elaborate our own analytical approach, which, more than Crossley’s, stresses the structural factors that formulate the conditions of group formation and struggle. Structural factors are conceived as elements of the field of contention which both produce the conflicts around which contention arises and influence relationship-making among actors. The chapter proposes an approach which can conceptualize both the antagonisms and solidarities in housing mobilization, as well as the parallel but ideologically polarized mobilizations of different groups in the same social-structural context. The approach developed is intended to capture and theorize such complexity of contemporary housing mobilizations.
