Supporters of divestment ended their encampment last spring in exchange for a promise that their proposal for divestment would get a vote from the board this fall.

After nearly a decade of student activist groups pushing for Brown University to divest its endowment from companies affiliated with Israel, the university’s governing board voted against the proposal on Tuesday. The timing of the vote came as a shock to the campus community, which expected a vote on divestment later this month.
