A crowd of thousands gathered in Washington to celebrate the Supreme Court striking down a part of a federal law denying federal benefits to married gay couples.
The court's 5-4 vote said the Defence of Marriage Act, known as Doma, denied equal protection to same-sex couples.
The ruling means that previous anti-gay marriage laws denying legally married same-sex couples from receiving tax, health and pension benefits has been swept away.
The court also upheld a trial court declaration that ruled that California's Proposition 8 was unconstitutional, paving the way for same-sex marriages to continue in the state.
Proposition 8 was approved in 2008 with 52% of the vote and put same-sex marriages on hold.
The verdict read:
"Under Doma, same-sex married couples have their lives burdened, by reason of government decree, in visible and public ways.
"Doma's principal effect is to identify a subset of state-sanctioned marriages and make them unequal."
President Obama has welcomed a US Supreme Court decision to make married gay men and women eligible for federal benefits, whilst stressing the ruling does not change the way religious institutions define marriage. In a written statement, he said:
We are a people who declared that we are all created equal, and the love we commit to one another must be equal as well.
The US president said the ruling applies only to civil marriages and that how religious institutions define and consecrate marriages has always been up to those institutions.
The US Supreme Court has extended Federal benefits to married gay couples.
Gay marriage campaigners have welcomed the House of Lords' decision to reject a bid aiming to block the legislation.
– Peter Tatchell, who co-ordinates the Equal Love campaign
This is a victory for love, marriage and equality.
We are another step closer to our goal of equal marriage. It signals that the House of Lords accepts the principle that we should all be equal before the law.
– Ben Summerskill, Stonewall chief executive
In the last 24 hours alone, opponents of equality in the House of Lords have compared loving, committed relationships to incest and polygamy.
Britain's 3.7 million gay people don't deserve to be second class citizens in their own country. A tough fight lies ahead and we'll continue to work tirelessly every single day to get equal marriage through the Lords.
An anti-gay marriage group said today's House of Lords vote showed there was "huge opposition to almost every part of the bill".
Peers rejected a bid to block the Government's plan to legalise gay marriage by 390 votes to 148.
– Colin Hart, Campaign Director for the Coalition for Marriage
The Government may have won the vote today but what was clear from the debate was the huge opposition to almost every part of the Bill.
We will continue to campaign to save traditional marriage and today's vote and the concerns expressed by many peers mean we will be able to introduce safeguards that will protect teachers, registrars, chaplains and anyone who works in the public sector. If the Government refuse to accept these changes, they risk losing the legislation at third reading.
