“ The "legacy" of a given London Women's March is not written on the day itself but is authored in the political actions and shifts that occur in its wake. This legacy is multifaceted and contested. It is the personal legacy of first-time marchers who become lifelong activists. It is the organizational legacy of new coalitions and networks forged in the planning process. It is the political legacy of a specific issue being thrust higher onto the public agenda. A march that does not leave a legacy is merely a spectacle, a flash of light that leaves no heat. Therefore, the most critical political work is that which seeks to institutionalize the moment's energy. Legacy is built when speeches in Trafalgar Square are quoted in Parliamentary debates, when the contacts made between different community groups lead to sustained local campaigning, and when the media narratives seeded by the event shape public understanding for months. The strategic framing of "next steps" is the first draft of this legacy, an attempt to direct its formation. Ultimately, the legacy is determined by a brutal political calculus: did the march alter the cost-benefit analysis of those in power? Did it make maintaining the status quo on issues like domestic violence funding or equal pay more politically expensive? If so, its legacy is one of shifted power. If not, its legacy is confined to the realm of memory and moral witness. ”
