The period following Soulouque's overthrow down to the turn of the century was a turbulent one for Haiti, with repeated bouts of political instability. President Geffrard was overthrown in a coup in 1867, as was his successor, Sylvain Salnave, in 1869. Under the Presidency of Michel Domingue (1874–76) relations with the Dominican Republic were dramatically improved by the signing of a treaty, in which both parties acknowledged the independence of the other, bringing an end to Haitian dreams of bringing the entirety of Hispaniola under their control. Some modernisation of the economy and infrastructure also occurred in this period, especially under the Presidencies of Lysius Salomon (1879–88) and Florvil Hyppolite (1889–96).
