Pedro Joseph Piernas was a Spanish military official who rose to the rank of commandant in 1768 and served as Lieutenant governor of Illinois between 1770 and 1775.
In 1747, Pedro Piernas is believed to have joined the Spanish Army and he probably obtained the ranks of infantry captain,colonel, commandant, and lieutenant.
Piernas had already ruled Upper Louisiana in 1768, but he arrived in Saint Louis on March 10, 1769 . In August of that year, he was appointed Lieutenant Governor of Illinois by Alejandro O'Reilly. The French commandant of the village, Louis Groston de Saint-Ange de Bellerive, transferred formal control to Piernas on May 20, 1770. St. Ange was then named assistant to Piernas and special adviser on Amerindian affairs. Piernas also made St. Ange an infantry captain in the service of the Spanish Crown and maintained friendly relations with him. After the transfer, Piernas confirmed St. Ange's and Laclède's land grants. He rented Laclède's headquarters as government offices, with Spanish soldiers providing local security.
When Piernas assumed the office of Lieutenant Governor of Upper Louisiana, he realized that the population rejected the Spanish government. Louisiana was French territory until the colony passed into Spanish hands under the terms of the Treaty of Paris at the end of the Seven Years' War) in 1763. Piernas immediately began working to reconcile the provincial public to the Spanish government; although he changed very little in the government of the colony, he introduced some new regulations that benefited the population.
Additionally, Piernas appointed Martin Duralde as Land surveyor to establish conclusive proof of the provincial borders. The appointment of a Frenchman as surveyor was unexpected and supported by the population. Piernas also publicly registered all donations that he had made without any legal requirement to do so. These acts of power, combined with a less oppressive government and the incorporation of French people in many subordinate offices, helped Piernas gain support as the new Spanish governor.
