Last year, an estimated 5 million protestors marched in an international mass demonstration the day after President Donald J. Trump’s inauguration. The Women’s March will return in 2018.

Kicking off in Las Vegas, Nevada, organizers say the new effort seeks to realize substantial political gains in this election year. Dubbed the “Power to the Polls” march, the mass demonstrations look to capture the momentum from the last year that saw a transgender woman of color elected to Minneapolis city council, Black men and women were elected mayors of Helena, Montana, Charlotte, North Carolina, and St. Paul, Minnesota, and an massive turnout of Black women defeated Roy Moore’s run for Senate in Alabama.

Las Vegas was chosen for its unique character as both a battleground state and the site of deadliest mass shooting by an individual in U.S. history.

Last year also saw the J20 protests during the Trump inauguration January 20. In the aftermath,  204 people, arrested en masse, were charged with riot-related felonies and misdemeanors. While an initial six defendants, including professionals such as journalists and nurses, were acquitted, the Department of Justice is still moving forward with charges on the remaining 188 defendants.

Late last January, after the announcement of Executive Order 13769, what has been called the Muslim ban, protestors severely compromised the operations of airports such as John F. Kennedy International, O’Hare International and Baltimore-Washington International. Demonstrations occurred at over twenty U.S. airports daily until early February. Matching protests took place in airports as far away as Manchester, England and Berlin, Germany.

Since then, various federal courts challenged the ban. In a 7-2 December decision, the Supreme Court allowed the President’s modified order 13780 to go in full effect. On Dec. 22, the Ninth Circuit Court ruled that the order “exceeds the scope of his delegated authority.”

The Women’s March will not be returning to Portland, Oregon this year, but will return to Oahu, Hawaii. Still devastated by Maria and an incomplete U.S. relief effort, Puerto Rico has not announced a Women’s March in 2018. The Florida Women’s March, encompassing Jacksonville, St. Petersburg, Orlando and Miami has announced it will be holding a donation drive for Puerto Rico, the U.S. Virgin Islands, and the Florida Keys all affected by Hurricane Maria.

Baltimore’s Women’s March will begin at City Hall in War Memorial Plaza. Starting at 11 a.m. a march will proceed from the plaza to McKeldin Square. Mayor Catherine E. Pugh, Sen. Ben Cardin and Maryland State’s Attorney Marilyn J. Mosby are expected to attend and speak.

2017’s Baltimore March, at North Charles Street and 33rd Street, drew almost 5,000 people while a sizable contingent travelled south to D.C. to protest at the nation’s capital.

“This resistance needs all of us, every day, fighting for the collective liberation of all people,” the Women’s March Global website says. “Because none of us are free until all of us are free.”
