The day聽after Donald Trump was elected President, a march in protest on Washington sprung up as an event on Facebook and very quickly聽had over 40,000 planning to attend, with over 100,000 marked as interested.

Originally聽called the Million Women March and聽planned for the day after Trump鈥檚 January 20 inauguration, the event, now known as the Women鈥檚 March on Washington, has become a full-on movement that鈥檚 expected to draw around 200,000 people (some of whom will even be traveling to the US聽for it). The mission of the march is to 鈥渟tand together in solidarity with our partners and children for the protection of our rights, our safety, our health, and our families.鈥

With well over a million more people planning to march in over 600 solidarity sister marches around the world, as well as with celebrity support from the increasingly politically outspoken聽Katy Perry, Amy Schumer, Cher and many, many more, the March is already making history, joining generations of hard-won victories, rallies and major milestones for women. Here are a few key moments to also keep in mind when marching with and for your sisters this weekend.

1. Abigail Adams鈥 letter (1776): Abigail was an early champion of women鈥檚 rights. In a letter to her husband John Adams, who later becomes the second US president, she famously urged lawmakers to 鈥渞emember the ladies鈥 when fighting for independence from Britain. The letter included this fire quote that still, sadly yet inspiringly, feels just as relevant: 鈥淚f particular care and attention is not paid to the ladies, we are determined to foment a rebellion, and will not hold ourselves bound by any laws in which we have no voice or representation.鈥 Told you: fire emojis.

2. The Seneca Falls Convention (1848):聽Spanning two days in July, the first women鈥檚 rights convention took place in Seneca Falls, NY, to 鈥渄iscuss the social, civil and religious condition and rights of woman.鈥 At the convention, co-organizer Elizabeth Cady Stanton, a leading figure of the early women鈥檚 rights movements,聽presented her聽Declaration of Sentiments, which many credit for initiating the women鈥檚 suffrage movement in the US.

3. The Suffrage Protest (1913): One of the suffrage movement鈥檚 biggest and most well-known protests聽happened the day before Woodrow Wilson鈥檚 Presidential Inauguration in聽1913. Approximately聽8,000 women seeking voting equality marched past the White House, with many being聽assaulted and injured by onlookers opposing the campaign. The violence against the protesters resulted in outrage and a deeper support for the suffrage movement.

4. Women Get the Right to Vote (1920): The 19th Amendment to the US Constitution is ratified, giving (some) women the legal right to vote. It鈥檚 worth noting that the first women鈥檚 suffrage petition was presented to UK Parliament in 1832.

5. The Equal Pay Act (1963):聽John F. Kennedy started the long road to pay parity by signing The Equal Pay Act, aiming to abolish wage disparity based on sex.

6. Civil Rights Act (1964): Although some US women gained the right to vote in 1920, African-American women in some Southern states remained聽subject to unfair voter registration requirements. It wasn鈥檛 until the Civil Rights Act was signed into law by President Lyndon B. Johnson in 1964 (1964!) that they were able to freely exercise their rights too.

7. 鈥淏ra Burning鈥 (1968):聽In 1968, a group of women protesting the Miss America pageant in聽Atlantic City threw what they saw as items of feminine oppression, such as makeup and, yep, bras, into a trash can. It was widely rumored that the trash can was set on fire, hence the myth of the bra-burning feminists that remains to this day.聽No fire was ever actually set, but the protest 鈥 and therefore feminism鈥檚 second wave 鈥 got tons of press and attention.

8. The聽Ladies鈥 Home Journal Sit-In (1970): How鈥檚 this for some inspiration: In March 1970, approximately 100 women stormed the Ladies鈥 Home Journal offices to protest the way the male-run magazine portrayed them, demanding the resignation of then Editor-in-Chief John Mack Carter in favor of an all-female editorial staff.聽They refused to leave for 11 hours, when John agreed to聽give the protestors聽their own聽section of the August issue. Three years later, senior editor Lenore Hershey took over as Editor-in-Chief of the magazine.

9. Equal Rights Amendment Marches (1970s): Passed by Congress in 1972, the ERA (which sought to聽guarantee women the same rights as men 鈥 how novel!) had 10 years to be ratified by 38 states, but some states stubbornly resisted, sparking many demonstrations throughout the decade. The biggest happened on Mother鈥檚 Day in 1980, when 90,000 people demonstrated in Chicago in support of the amendment. The聽marches聽remain a major effort聽of the modern women鈥檚 movement.

10. Roe v Wade (1973): The historic Supreme Court decision that legalized abortion. Roe v Wade feels particularly precarious in 2017 as Trump鈥檚 presidency is already changing聽reproductive rights.

11. Take Back the Night (1975):聽The earliest Take Back the Night March, which saw women walk through the聽streets at night with candles, occurred in Philadelphia in 1975 in response to an increasing amount of聽violent crimes against women. Take Back the Night is now an official organization that focuses specifically on sexual violence against women, and marches happen all over the world every year.

12. Women鈥檚 History Month (1987): Congress expands Women鈥檚 History Week, first celebrated in California in 1978, to a month-long event celebrated annually in March.

13. Violence Against Women Act (1994): Signed by President Bill Clinton (and under the leadership of then-Senator Joe Biden) in September 1994, this act provided funding and legislation for聽the investigation and prosecution of domestic and sexual violence against women.

14. Million Mom March (2000): Held on Mother鈥檚 Day in May 2000, hundreds of thousands of聽people showed up for this word-of-mouth, grassroots protest聽at聽Washington鈥檚 National Mall to advocate for more strict聽gun control, displaying the names of over 4,000 victims of accidental child firearm deaths. With the聽marches that followed in聽other cities,聽the Million Mom March brought out almost a million protestors.

15. March for Women鈥檚 Lives (2004): President George W. Bush鈥檚 anti-abortion policies brought聽somewhere between 500,000 to 800,000 people聽to Washington to march for women鈥檚 reproductive rights and to protest Bush鈥檚 reelection. The March聽was supported by the likes of Julianne Moore聽and Susan Sarandon, among others. Bush served a second term.

16. Slutwalk (2011): Though the Slutwalk originated in Toronto after a police officer said聽women shouldn鈥檛 鈥渄ress like sluts,鈥 more than 50 sister聽walks have taken place in major cities around the world. Amber Rose has specifically brought a ton of visibility to the Walk聽through her annual LA SlutWalk.

17. Lilly Ledbetter Fair Pay Act (2009):聽The gender pay gap took another small but important hit when Obama signed the Lilly Ledbetter Fair Pay Act into law in 2009, allowing employees to file lawsuits regarding equal pay for up to 180 days after receiving a discriminatory paycheck. It was during Lilly Ledbetter鈥檚 time as a production supervisor at an Alabama Goodyear tire plant when she filed an equal-pay lawsuit regarding pay discrimination under the Civil Rights Act of 1964.

18. Black Lives Matter (2013):聽BLM was founded by a group of female activists in 2013 after George Zimmerman was acquitted聽for the shooting death of Trayvon Martin, and has聽surged in scope聽as the police killings聽of African Americans became a bigger part of the national conversation in the years following. The hashtag #SayHerName was also launched聽to focus on聽violence against black women and girls, and names like Rekia Boyd, Sandra Bland and Kayla Moore also got due聽attention in聽the conversation.

19. Women鈥檚 Expanded Roles in the Armed Forces (2016): Defense Secretary Ash Carter finalized the allowance of women to have any job in the armed services, pending the passing of non-discriminatory performance tests. The move opened up聽approximately 220,000 jobs to women.
