June 14: (from an interview with David DeGraw, organizer from OWS on 11-6-11 from Los Angeles livestream conference)
First attempt at an occupation of Zucotti park, but less than 20 people showed up. Later that night they met up with the people camping in "Bloombergville" (see below, June 14), and the merger of these two groups became the first NYC GA.

Over 1,000 protesters arrive at Veteran’s Memorial Plaza for a day of Occupation. About 100 break off to occupy the Statehouse lawn for the night.

Origin of this Brief History
The Indianapolis Occupation has been plagued with self-doubt arising from the perceived uniqueness of challenges we have faced. I had a conversation with one of the OWS organizers who helped me understand that Indianapolis is on the same trajectory that NYC faced. Their experiments in occupying public spaces started as early as June, and people have been getting arrested in mass Wall Street protests since at least April. The city this year has had multiple large-scale protests against government budget cuts to the poor and to schools, while bailing out banks. Adbusters has publicly floated the idea of the Wall Street protests since February, and officially announced the campaign in July. We aren’t a failure because we haven’t been able to “Occupy” Indianapolis in 2 days. We skipped the planning, organizing, and preparation phases, yet expected to be another Occupy Wall Street New York. It has been a 9 month project for New York, with starts and fits just like we had, and numerous protest/occupy experiments before the Sept 17th date to get them ready.

We are doing fine. We need to press forward. We are the 99%
