Divestment was also used against South Africa to help end apartheid: Wikipedia
Disinvestment (or divestment) from South Africa was first advocated in the 1960s in protest against South Africa’s system of apartheid, but was not implemented on a significant scale until the mid-1980s. A disinvestment policy the US adopted in 1986 in response to the disinvestment campaign is credited with playing a role in pressuring the South African government to embark on negotiations that ultimately led to the dismantling of the apartheid system.
