This paper analyzes how collective leadership develops from more individualistic leadership through ethnographic analysis of the rise of urban environmental stewardship in Grand Rapids, Michigan. Longitudinal analysis of a 30-year period reveals how leadership shifted from being highly individualistic, to become more pluralistic, and ultimately more collective. I demonstrate how specifying the location of leadership action in the case addresses ambiguity regarding the definitions of and distinctions among collective, plural, and integrative leadership. I identify two processes that helped to relocate leadership from more individualistic to increasingly collective, emergent spaces, namely fueling a public imaginary and organizing inclusively. These processes were central to connecting and mutually advancing collective leadership and collective impact.
