See how people around the country are celebrating the landmark legalization of gay marriage

After the Supreme Court's landmark 5-4 ruling legalizing same-sex marriage nationwide Friday, people everywhere had a major reason to celebrate.

Justice Anthony Kennedy issued the 5-4 ruling, finding that the Fourteenth Amendment - which guarantees "equal protection under the law" and the right to "due process of law" - requires a state to license a marriage between two people of the same sex.

Festivities across the country started just moments after the ruling. Take a look at how people celebrated the victory from Washington DC to San Francisco.

Outside the Supreme Court, crowds cheered and hugged one another. 

The Gay & Lesbian Advocates & Defenders (GLAD) offices in Boston were overjoyed at the decision.

 Much of Boston shares the same spirit.

Lots of excitement at The Huffington Post in New York.

... and at the Stonewall Inn in Greenwich Village, considered the starting place of the modern gay liberation movement, a crowd had just started to filter in. 

And out on the West Coast, pride is in the air - this is in San Francisco.

The good news reached Atlanta, too.

 The rainbow flag promptly went up at the city hall in Chicago.
