Gregorio Pacheco Leyes (July 4, 1823 – August 20, 1899) is the constitutional President of Bolivia from 1884 to 1888.
A native of Livilivi, Province of Potosí, Pacheco wins a disputed election that is a virtual three-way tie between him, Conservative leader Aniceto Arce, and Liberal chief Eliodoro Camacho.
Pacheco is a self-made wealthy man (he was born poor) and the country's foremost philanthropist.
He had made his money purchasing shares in defunct silver mines which he rehabilitated.
By the mid 19th century Pacheco emerges as a wealthy, efficient, progressive, and pragmatic silver tycoon.
Bolivia's state of instability, fraught with coups and international conflicts concerns him greatly. .
