This year's election is drawing comparisons to the 1992 elections dubbed the "Year of the Woman", when a record number of women won seats in Congress, bringing total representation to around 10 percent.
Women also contested governor's races across the country.
Beyond the election night tallies, female candidates also shattered long-held gender stereotypes about how women should run for office.
In split-gender races, women have won 65 races and lost 101, but this is not necessarily a strong indication of gender bias.
The victory made her the national face of young, discontented Democrats - often women and minorities - trying to drag their party to the left.More news: EPL: Chelsea identify Premier League star to replace Morata, Giroud
"This is a pretty exciting time because we will increase our numbers drastically and what I want for those women, I want them to serve in the majority on the Democratic side", said Mrs Pelosi of California. The victories by the two Democrats - Ilhan Omar and Rashida Tlaib - came on an election night when members of multiple minority groups had a chance to score electoral firsts.

In races still too close to call, Abrams, if elected, would become the first female African-American governor in US history, and in Arizona's competitive Senate race, the state will elect either Republican Martha McSally or Democrat Kyrsten Sinema as the state's first woman to serve in the chamber. "So that's our objective".
If more than 84 of those women candidates won on Tuesday, it would set a record for the number of women serving in the House.More news: A Breaking Bad movie could come from creator Vince Gilligan
"Tonight, we reaffirm what an wonderful state that we live in", he said in his victory speech.
"It may be women candidates who save our enthusiasm advantage by mobilizing women voters", Lake said. "This could be the beginning of a decade of the woman where you have more women running and moving up because you filled the pipeline". Vermont has never sent a woman to Congress.
