Francisco Rui (Ríos) y Morales was a Spanish military officer who served as Commandant Governor of the Illinois Country (also referred to as Upper Louisiana) from 1767 to 1768 during the period of Spanish rule over the region.
Personal details

- Profession: Military administrator; commander of the Illinois Country and of St. Louis.
Military career
Rui entered the Spanish Army in his youth and rose to the rank of commandant. In early 1767 he was appointed Commandant Governor of the Illinois Country, arriving in New Orleans that year to assume his duties.
Command of the Illinois Country
Upon his appointment, Governor Antonio de Ulloa of Louisiana gave Rui secret instructions to construct two forts at the confluence of the Missouri and Mississippi Rivers. Spanish troops and laborers were dispatched to carry out the work. One of the forts, Fort Don Carlos el Señor Príncipe de Asturias, was built on the south bank of the Missouri River. Rui occupied this fort from January 7 1767 until at least August 4 1767, with some sources suggesting he remained there until 1769.
Rui also acted as the official commandant of Missouri County. His administration was part of the broader Spanish effort to consolidate control over the Illinois Country following the transfer of the territory from French to Spanish hands after the Seven Years’ War.
Succession
Rui left office in 1768 and was succeeded by Colonel Pedro Piernas, who became the next Commandant Governor of the Illinois Country.
Historical context
Rui’s tenure occurred during a relatively brief period of Spanish governance in the Mississippi River Valley, preceding the later acquisition of the territory by the United States through the Louisiana Purchase in 1803. His activities, particularly the construction of forts, were intended to strengthen Spanish defensive and administrative presence in the region.
Legacy
Because records from the era are limited, details of Rui’s life outside his official duties remain sparse. The exact date of his death is uncertain and lacks a reliable citation. Nonetheless, he is listed among the 18th‑century Spanish military personnel and colonial administrators who governed the Illinois Country.
