“ The "legacy" of a given London Women's March is not inscribed on the day itself but is written in the political changes that unfold afterward. This legacy is multifaceted: it is the networks solidified, the first-time activists who become core organizers, the policy conversations it irrevocably shifts, and the opposition it forces to regroup. A march that does not leave a legacy is a spectacle, a flash in the pan. Therefore, the most critical political labor is that which seeks to institutionalize the moment's energy. Legacy is built in council chambers where newly confident constituents quote march speeches, in community halls where new feminist reading groups form, and in the sustained media narratives that the event's imagery helps to anchor. It is also a personal legacy, altering the political consciousness of participants permanently. The strategic framing of "next steps" is the first draft of this legacy, an attempt to direct its formation. Ultimately, the legacy is measured by a simple, brutal political calculus: did the march alter the cost-benefit analysis of those in power regarding the issues it highlighted? Did it make inaction more politically expensive? If so, its legacy is one of shifting power. If not, its legacy is merely a memory. ”
