Women’s March on Washington: 11 Things You Should Know About the Event

4. Protesters have already been banned from prime spots.

Every march needs a meeting place and a predetermined route, which has been a little tricky to plan for a demonstration of this size. (According to some reports, the number of expected participants is in the hundreds of thousands.) The Women’s March website says the demonstration will start at Independence Avenue and Third Street SW. But the most visible spots in Washington D.C.—that is, the National Mall, Pennsylvania Avenue, the Washington Monument, and the Lincoln Memorial—will be blocked to protesters. Typically, the National Park Service grants First Amendment permits to protesters wanting to use the iconic areas, but this year, according to the Guardian, the Park Service is blocking all protesters on behalf of the Presidential Inauguration Committee.

Despite the setback, the organizers are undeterred. “The planning process will be ongoing until days before the march, and we will continue to work closely with the National Park Service, Metropolitan Police Department, Homeland Security, Capitol Police, and other agencies to ensure a safe march with all logistics in place to accommodate the number of people we anticipate convening,” organizers said in a statement on the march’s official site.

5. It’s not just a symbolic gesture.

The official Unity Principles driving the Women’s March are ending violence, preserving and expanding reproductive freedoms, and heightening awareness of LGBTQIA rights, workers’ rights, civil rights, freedom of speech, protections for all citizens regardless of race, gender, age, or disability (and a call for federal adoption of an Equal Rights Amendment to the U.S. constitution), disability rights, immigrant rights (and a denouncement of the word “illegal”), and environmental justice.
