More than 1 million people around the world are expected to hit the streets Saturday to advocate for gun safety in what some reports are saying will be one of the largest marches in history.

Students from Marjory Stoneman Douglas High School in Parkland, Florida, organized the March For Our Lives rally after 17 people were killed at their school on Feb. 14.

Six weeks after the tragedy, organizers have brought the debate about gun control to the national forefront, and according to the mission statement for March for Our Lives, organizers want to put an end to gun violence in schools.

Not one more. We cannot allow one more child to be shot at school. We cannot allow one more teacher to make a choice to jump in front of a firing assault rifle to save the lives of students. We cannot allow one more family to wait for a call or text that never comes. Our schools are unsafe. Our children and teachers are dying. We must make it our top priority to save these lives.

Survivors of the school shooting have sat down with President Donald Trump and challenged senators on their support of the National Rifle Association.

The mounting pressure about gun control even prompted Florida Gov. Rick Scott to sign a law that tightened rules in the state, much to the NRA’s objections.

On March 14, Woman’s March organizers organized a national school walkout, which led to thousands of students around the country to walk out of their schools for 17 minutes; one minute for each victim of the Parkland shooting.

Celebrities including Oprah Winfrey, John Legend, and George and Amal Clooney have donated thousands of dollars in support of the organization. Dwyane Wade and Gabrielle Union have donated $200,000 to send students to the rally in Chicago.

The grass-roots movement has raised over $4 million, according to ABC News. 

Over 500,000 people are expected at the main rally in Washington, D.C., and thousands more at rallies in NYC, Boston and Los Angeles, according to multiple reports.

There will be a reported 800 marches worldwide, with most being in the U.S.
