In the wake of the civil rights movement, new organizations formed which were based on the collective interests and identities of their constituencies. Some of these organizations brought together national origin groups who often differed by ethnicity, language, culture, religion and immigration history. In this paper, 1 focus on the conditions that facilitate the institutionalization of a socially constructed panethnic community. Using a new longitudinal data set of Asian American organizations, I draw upon a theory of panethnicity which emphasizes the structured relations between groups at different boundary levels to understand panethnic organizational foundings. When controlling for resource availability, political opportunities and organizational dynamics, the boundary formation variables remain important in explaining new organizational activity.Since the 1970s, organizational activity based on a collective identity derived from members' common interests and experiences has become an increasingly prevalent option for social change efforts. The organizational forms that emerged during the Civil Rights era illuminate the new ways in which groups not only fulfilled the social and economic needs of their respective communities, but demonstrate how ethnic minorities were able to institute collective identities and provide a framework for the articulation of group interests. Some of these organizations served and brought together national origin groups who often differed by language, culture, religion and immigration history. Based on the socially constructed notion of a panethnic community, organizations such as the National Council of La Raza, Asian Pacific American Labor Alliance and the National Urban Indian Development Corporation played an important role in securing civil rights for their respective communities by providing services and advocacy for different ethnic and tribal communities under a unified panethnic framework while contributing to the creation of new cultural and political identities. Recently, such organizations have been successful in campaigns against anti-immigrant legislation, unfair wages, poor working conditions and the Jack of affordable housing and economic opportunities. Under what conditions are national-origin groups who differ by language, culture, collective history, religion and immigration status able to construct a panethnic identity upon which to form a larger collective? What conditions influence the institutionalization of a socially constructed panethnic community?
