The International Meridian Conference, held in Washington DC in 1884, adopted a number of resolutions of which the first two were:
- That it is the opinion of this Congress that it is desirable to adopt a single prime meridian for all nations, in place of the multiplicity of initial meridians which now exist.
- That the Conference proposes to the Governments here represented the adoption of the meridian passing through the centre of the transit instrument at the Observatory of Greenwich as the initial meridian for longitude.
The second resolution was passed by 22 votes to one (the Dominican Republic, for some reason, voted against – one wonders what they were doing there anyway). Brazil and France abstained.
