Summary

In April 1985, students at Columbia University in New York City, organized by the Coalition for a Free South Africa (CFSA), blockaded the administrative building Hamilton Hall to demand total divestiture from corporations operating in apartheid South Africa. The blockade grew to involve thousands of students and drew national attention. After the blockade ended, a trustee panel recommended divestment, and the full board adopted the recommendation in October 1985, leading to full divestiture.

Background

Black Africans in South Africa had been oppressed by colonial and apartheid governments since the early 19th century. Columbia University held investments in corporations operating in South Africa, and student activists sought total divestiture as a moral and economic stance against apartheid.

What happened

On April 4, 1985, seven CFSA members chained closed the doors of Hamilton Hall and blockaded the entrance, joined within hours by over 250 students [source: nv-database]. The blockade was the culmination of years of activism; CFSA had formed in 1982 and previously secured supportive motions from the Student Senate and University Senate, but the Trustees stalled [source: nv-database]. The CFSA planned the blockade for two months, with seven leaders beginning a fast a week beforehand [source: nv-database]. The blockade drew immediate news attention, and the university threatened expulsion and criminal charges, but a sympathetic judge issued a restraining order preventing police action [source: nv-database]. The student grocery store donated supplies, African-American alumni assisted with publicity, and leaders like Jesse Jackson and Desmond Tutu declared solidarity [source: nv-database]. On April 8, the fasters met with President Michael Sovern and ended their fast, but the blockade continued [source: nv-database]. At its height, 1,000 students sat on the steps at all times, and when Jesse Jackson spoke, over 5,000 attended [source: nv-database]. The blockade ended on April 25 with a march into Harlem, and CFSA threatened continued action [source: nv-database]. A six-trustee panel formed immediately after, and in late August it confirmed that divestiture was both moral and economically viable [source: nv-database]. On October 7, the full board of 24 Trustees adopted the recommendation and proceeded to divest all remaining South Africa-related investments [source: nv-database].

Tactics used

The campaign combined a sustained nonviolent blockade with fasting, public speeches, marches, petitions, and coalition-building to maintain pressure and visibility, forcing the university to address the divestment demand. [source: nv-database]

Outcome

Verdict: won.

The campaign achieved full divestiture: the Trustees adopted the panel’s recommendation and divested all South Africa-related investments, meeting the students’ demand for total divestiture. The outcome is classified as won because all six points for success were achieved. [source: nv-database]

Lessons

  • Sustained nonviolent direct action like blockades can force institutional decision-makers to form committees that may recommend the desired change.
  • Building broad coalitions with alumni, community groups, and prominent figures amplifies pressure and sustains media attention.
  • Careful planning to ensure safety and legality (e.g., marking alternate exits) can undermine claims of disruption and reduce repressive violence.
