Gay allies in Congress have introduced a resolution that would recognize the birth of the modern gay rights movement.

Three openly gay representatives – Tammy Baldwin of Wisconsin, Barney Frank of Massachusetts and Jared Polis of Colorado – along with Jerrold Nadler of New York have introduced a resolution that would recognize the 40th anniversary of the Stonewall riots.

The riots, which took place in Greenwich Village, are often credited for sparking the modern gay rights movement when patrons of the Stonewall Inn, mostly drag queens, rebelled against police harassment in 1969. Rioters violently fought back against officers over the course of several days starting on June 28.

“We honor all those who stood their ground at Stonewall as we carry on their quest for full and equal rights for all Americans,” Baldwin said in a statement.

“As we move ahead in the movement for legal equality, it is important to remember those who had the courage to fight hard when things were much tougher,” Frank said.

Last month, New York City unveiled a new marketing effort titled Rainbow Pilgrimage Campaign. The $1.9 million campaign urges gay men and lesbians to visit the birthplace of the gay movement in Manhattan during its 40th anniversary.

“The events at Stonewall 40 years ago had a profound effect on how LGBT Americans came to see their struggle for equality,” Nadler, who represents Greenwich Village, said. “Stonewall catalyzed gay Americans – and those who support their rights – into putting gay rights on the forefront, out in the open, unafraid and unapologetic.”

A spokesman for Nadler told San Francisco Chronicle blogger Carla Marinucci that the resolution is expected to pass in June, ahead of New York City's June 28 gay and lesbian pride parade and march.

UPDATE: Ilan Kayatsky, the spokesman for Nadler, has clarified his statement and Marinucci has updated her blog post. Kayatsky told On Top Magazine that Nadler is "hopeful" the resolution passes in June.
