Protesters will mark the anniversary of the Occupy Wall Street movement today with rallies in more than 30 cities around the world, including a march on the New York Stock Exchange, not far from the park where the movement was born.
But as the last of its urban encampments close and interest wanes in a movement without an organizational hierarchy or an action agenda, it's unclear whether Occupy's first birthday will be its last.
Hector Cordero-Guzman, a City University of New York sociologist who has studied the movement, says it has made an impact. Many of its complaints and some of its rhetoric -- notably "We are the 99%!" -- have become the stuff of mainstream politics.
Occupy, he says, "changed the political conversation from where it was last summer. Income inequality, money in politics, the influence of Wall Street -- you can see those now in the presidential campaign. You see it in questions about Bain Capital and about Mitt Romney's tax returns."
He was referring to Democratic claims that the GOP nominee's venture capital firm profited by cutting jobs at companies it bought and to Democratic calls for Romney to release more information about his personal income taxes.
About 300 people observing the anniversary marched in New York on Saturday, the first of three days of rallies, teach-ins and other events designed to mark the year since protesters first gathered last Sept. 17 at Zuccotti Park in Lower Manhattan.
At least a dozen were arrested, mostly on charges of disorderly conduct, police said.
The anniversary comes as Occupy encampments continue to close.
A week ago, Occupy protesters abandoned their spot in front of the Ohio Statehouse in Columbus after getting an eviction notice from the city for failing to obtain a $100 permit and lay down a security deposit of at least $500.
In Tampa, Occupy members on Saturday moved out of a private park where they'd been ensconced for eight months with permission from its owner. Neighborhood residents complained that the tent city had become an eyesore populated mostly by the homeless.
Jared Hamil of Occupy Tampa says members probably would reform into a network of smaller groups.
At the political conventions this summer, Occupy's ability to mobilize large street protests seemed spent.
Cordero-Guzman predicts the movement will survive the loss of its urban encampments, because it's changing: "They're in a second wave now. Connections have been made; they have social media. They don't need the camps as much as they did."
