A long-running territorial dispute over the border between Venezuela and the British colony of British Guiana prompted the two parties to seek resolution. The Arbitral Treaty of Washington D.C., signed on 2 February 1897, established an international arbitral tribunal to adjudicate the boundary question amicably.
On 3 October 1899, the arbitral tribunal convened in Paris issued its award, defining the border to the west of British Guiana and east of Venezuela. The United States represented Venezuela in the proceedings, while the United Kingdom acted on behalf of British Guiana.
Venezuela protested the award in 1962 before the United Nations following publication of the Mallet-Prevost Memorandum, alleging the process was flawed. This led to the Geneva Agreement of 17 February 1966, which acknowledged Venezuela's claim regarding the award's validity, though the border controversy has remained unresolved.
Political Outcome
The arbitral tribunal delimited the Venezuela–British Guiana border; Venezuela later contested the award's validity, leading to the 1966 Geneva Agreement acknowledging the dispute remains open.
