While the mention of common purpose is prevalent in leadership studies, there are few attempts to explore the relationship between common purpose and leadership. This study delves into the questions of if and how common purpose and leadership inform one another. How leaders adapt purpose and leadership approaches in response to evolving and turbulent conditions may foster the depth and sustainment of immediate and subsequent accomplishments. Through phenomenological research in the venue of nuclear weapons reduction, a common purpose that is both globally pervasive and imbued with a sense of urgency, the lived essence of those engaged in common purpose can be illustrated. Exploring the symbiosis of the nuclear weapons reduction common purpose and associated leadership may have theoretical implications or provide lessons that can be utilized within other common purpose settings.
