Blood diamonds (also called conflict diamonds, war diamonds, hot diamonds, or red diamonds") is a term used for a diamond mined in a war zone and sold to finance an insurgency, an invading army's war efforts, or a warlord's activity. The term is used to highlight the negative consequences of the diamond trade in certain areas, or to label an individual diamond as having come from such an area. Diamonds mined during the recent civil wars in Angola, Ivory Coast, Sierra Leone, and other nations have been given the label. The term conflict resource refers to analogous situations involving other natural resources.
Angola, a colony of Portugal, gained independence on November 11, 1975. Although independent, the Popular Movement for the Liberation of Angola (MPLA), the National Union for the Total Independence of Angola (UNITA), and the National Liberation Front of Angola (FNLA) fought in a civil war from 1974 to 2001. Between 1992 and 1998, in violation of the 1991 Bicesse Accords, UNITA sold diamonds, valued at US$3.72 billion, to finance its war with the government.
The U.N. recognized the role that diamonds played in funding the UNITA rebels and in 1998 passed United Nations Security Council Resolution 1173 and United Nations Security Council Resolution 1176, banning the purchase of Blood diamonds from Angola. Resolution 1173 was the first resolution by the UN which specifically mentioned diamonds in the context of funding a war.
