Inauguration Day already was historic for women, with Kamala Harris becoming the first woman and person of color to become vice president, and she soon could be joined by a similarly record-breaking Cabinet.
Twelve of Biden's nominations for Cabinet and Cabinet-level positions are women, including eight women of color, and if they're all confirmed it would shatter former President Bill Clinton's record of nine women serving concurrently, which happened during his second term.
When former President Donald Trump was in office, six women served at the same time, excluding two who served in acting roles, per Rutgers University's Center of American Women and Politics
"Joe Biden made a commitment during his campaign that he would work to be sure that his administration looks like the constituencies it serves," Kelly Dittmar, director of research at CAWP, told ABC News. "I think what we're seeing in his Cabinet is that he's gotten pretty close to making good on that promise."
"These women will bring diverse lived experiences and perspectives to the work that they do, which is some of the most important policy work for the country," she added. "They're heading agencies that will set the terms and agenda for the next four years."
Here are the women nominated to Cabinet and Cabinet-level positions by Biden:
Rep. Marcia Fudge, D-Ohio, has been nominated to serve as secretary of Housing and Urban Development. She's a former chair of the Congressional Black Caucus.
Former Michigan Gov. Jennifer Granholm, who worked closely with the Obama administration amid the 2009 recession, has been nominated to head the Department of Energy.
Isabel Guzman, director of the Office of the Small Business Advocate in California, has been selected to serve as administrator of the Small Business Administration.
Rep. Deb Haaland, D-N.M., who made history by becoming one of the first two Native American women elected to Congress in 2018, has been nominated to lead the Department of the Interior. If confirmed by the Senate, Haaland would be the first Native person to oversee an agency that played a major role historically in the forced relocation and oppression of Indigenous people.
Avril Haines was selected for the role of director of national intelligence. Haines is a former deputy director of the CIA and principal deputy national security adviser under the Obama administration -- the first woman to hold both roles.
Rhode Island Gov. Gina Raimondo was nominated to head the Department of Commerce. She was elected governor in 2014 and is a former chair of the Democratic Governors Association.
Cecilia Rouse Chair, an economist and dean of Princeton University's School of Public and International Affairs, was nominated to lead the president's Council of Economic Advisers.
Katherine Tai, who serves as chief trade counsel for the United States House Committee on Ways and Means, was chosen for the position of U.S. trade representative.
Neera Tanden, a longtime policy adviser and president of the Center of American Program was nominated to serve as director of the Office of Management and Budget.
Linda Thomas-Greenfield, a career foreign service officer who served as assistant secretary of state for Africa during the Obama administration, was tapped to serve as U.S. ambassador to the United Nations.
Janet Yellen, the first woman to head the Federal Reserve, was nominated as secretary of the U.S. Treasury.
As it takes shape, the Biden administration has been widely praised for being the most diverse in history, but some progressives have voiced concerns over lobbying and corporate ties of some nominees.
Nominees like Tanden have drawn intense criticism from Republicans, with some vowing to block her confirmation.
Once the gavel switches and incoming Democratic Georgia Sens. Jon Ossoff and Raphael Warnock are sworn in, the Democratic Party will hold a slim majority in the upper chamber, with Harris as the tie-breaking vote.
