摘要:For centuries, groups and individuals have continually resisted unjust social processes and structures by asserting their political agency through sustained collective actions. While these actions have varied depending on particular circumstances and locations, they have always been greatly determined by the historical context in which they have occurred. Thus, as the world was organized through the construction of modern nation states in the eighteenth and nineteenth centuries, localized actions against immediate authorities diminished and modern forms of social movements emerged within a national context (Tilly 1984). In turn, transformations that have occurred on a global scale in the latter half of the twentieth century have begun to alter the ways in which collective action is carried out. In the context of an integrated and increasingly pervasive global economy, many social movements have recognized the extent to which overarching global economic processes can exert influence over social, political, economic, and ecological circumstances in local and national realms. In contrast to past movements that operated solely within the nation state and international state system, several movements have responded strategically to the transnational practices of global capitalism by fostering connections with an expanding web of transnational networks that allow for interactions with globally dispersed allies and opponents. As such, their political activities have expanded beyond the state to include actions at transnational and global scales.
