Treaty of Paris (1900)
The Treaty of Paris was signed on June 27, 1900 between representatives of the Kingdom of Spain and the French Third Republic, regarding Río Muni and Río de Oro in Africa.
Based on the terms of the treaty, Río Muni was relieved of all conflicting claims. Spain was left with a mere 26,000 km2 out of the 300,000 stretching east to the Ubangi River which they initially claimed. Moreover, the treaty granted the French the right to pre-emptively seize all territories if Spain decided to abandon its possessions in Río Muni.
