Reclaim Philadelphia was founded after Bernie Sanders had suspended his 2016 presidential campaign, as several Philadelphia-based activists disappointed with his loss decided to form an activist group in order to continue to advocate for what they viewed as progressive policies.[4] The victory of Donald Trump in that year's presidential election galvanised the group, which began to hold more regular meetings as a result.[5] Officially the Philadelphia chapter of the national group Our Revolution, Reclaim was active in Larry Krasner's successful 2017 campaign to become Philadelphia district attorney, credited by Krasner as having a "key role" in his victory.[6] In the 2018 election cycle, Reclaim members took control of the 1st and 2nd Philadelphia wards, located in South Philadelphia.[6] Reclaim is noted for its approach to city politics, instructing its members to run for the position of Democratic committeeman in their local area as a way to take control of the Philadelphia ward system.[7]
