One month ago, several hundred demonstrators gathered together in New York City to protest Wall Street.

Their demands were somewhat broad, they had no clear leaders and no political affiliation.

What was clear was that they were fed up with the top-down economy and were united by their anger over the gap between the rich and the poor.

That movement has quickly gained traction, spreading to hundreds of cities around the world from Occupy Hong Kong to Occupy London and Occupy Vancouver.

Following are 10 key moments in the Occupy Wall Street movement as it has made its way around the globe.

July 13: Adbusters, the Canadian anti-corporate publication, plants the seed that will grow into a global movement. Editors at the Vancouver-based magazine, inspired by Arab Spring events in the Middle East and North Africa, call on readers to form "one big swarm of people" to call for change.

"The time has come to deploy this emerging stratagem against the greatest corrupter of our democracy: Wall Street, the financial Gomorrah of America," Adbusters wrote, calling for supporters to flood into Lower Manhattan on Sept. 17. They did.

Sept. 17: It begins. The social media dialogue around #OccupyWallStreet has become a storm of Tweets and Facebook messages as demonstrators answer Adbusters' call and make their way to New York's financial district to demonstrate, chanting slogans such as "We are the 99 per cent" in reference to the fact that 1 per cent of the U.S. population owns 30 per cent of the wealth. Protesters set up camp in Zuccotti Park, which becomes a base camp of sorts for the movement.

Oct. 2: Roughly 500 protesters are arrested in New York, mostly for disorderly conduct and resisting arrest, after swarming the Brooklyn Bridge and blocking traffic for several hours. Many demonstrators claimed police had lured them into a trap, allowing them to congregate on the bridge, then switching tactics and making arrests.

Oct. 15: Wikileaks founder Julian Assange speaks to Occupy London protesters in the U.K., applauding the movement and complaining about Guantanamo Bay and money laundering in the Cayman Islands and London, before grabbing a handful of candy from a girl who was giving it out to the crowd, and throwing the sweets to the demonstrators, before leaving with his security guards.

Oct. 16: Tensions are on the rise in London, England, as police try to relocate protesters from their location at St. Paul's Cathedral near the London Stock Exchange. However, senior priest Giles Fraser steps in and tells officers that the Occupy London demonstrators are more than welcome to stay.

Oct. 17: An Occupy Wall Street demonstrator in New York brought his girlfriend to Liberty Plaza and asked her to "occupy his life." The man used the so-called people's mic, whereby the crowd shouts back a speaker's words, to make his proposal.

"I don't know what's going to happen to this moment but I hope it's half as successful as our marriage is going to be," the man said, the crowd faithfully repeating his words. "So Deb, will you occupy my life?" She said yes.
