Gregorio Pacheco Leyes (4 July 1823 – 20 August 1899) was a Bolivian businessman and entrepreneur who served as the 21st president of Bolivia from 1884 to 1888.

[2] It was now up to Pacheco to guide his nation to the path of peace and order, since it was only four years prior that the War of the Pacific, in which Bolivia lost its coastal provinces, devastated the country.

[4] In order to incorporate distant territories into the national sphere, he founded Puerto Pacheco on 13 July 1885, located on the right bank of the Paraguay River.

During his presidency, the first international telegraphic service from La Paz to Lima was inaugurated and the Banco Hipotecario was opened in Sucre.

Other acts include: A unique characteristic of Pacheco was his philanthropy since he partook in many charitable works with his own money,[1] spending his vast wealth he had acquired as silver tycoon.

Although conservative by temperament, he was originally not a member of Arce's party, and ran against him, as well as against the Liberals, on the basis of his personal resources and fame as an efficient administrator.

[3] Arce, in fact, initially resented Pacheco's intrusion in politics, understanding that no one in the country could match his personal fortune, which would no doubt make him hard to beat.
