Rafael Zaldívar (San Alejo, 1834 - Paris, 2 March 1903) was President of El Salvador from 1 May 1876 until 21 June 1885. He studied medicine in Europe and began his career as a physician. In 1860 he was appointed to the Chair of Philosophy and Hygiene at the University of Guatemala. After leaving this post, Zaldívar entered politics and was elected to the House of Representatives, then to the Senate, and finally elected president in 1876.
It was under his administration that liberal reforms abolished the existence of collectively owned ejidos and tierras comunales throughout the country. President Zaldivar was not in favour of the proposed rebirth of the Unified Central Republic agreed to by his predecessors and decided to withdraw from the Union. He was later overthrown in a military coup and succeeded by General Francisco Menéndez. He died in Paris in 1903 while serving as his country's minister to France.
Rafael Zaldívar also remains a key figure in what later became known as the "Coffee Revolution." It was Rafael Zaldívar who introduced reforms that paved the way for cultivation on large scale. Under the Zaldívar administration, virgin land was turned into farmlands. This was done by allowing for the sale of Indian lands. Resistance resulted from the Indians, but it quelled by the Zaldívar government, mostly by creating a then deploying a rural police force.
