Clemente I

 (Clemente Ploerio Carres Abarca, November 24, 926 – October 6, 972) was the first king of Ventora (959–972) and last Duke of Plenas (954–972).

Family
Born at Plenas on November 24, 926, Clemente Ploerio was the eldest son of Próspero Lepho Carres Lepe, Duke of Plenas, and Conchita Teresa Abarca Tremanca. He married Anabel Trena Olguín Dalí, Countess of Olguín, on February 25, 950. They had two sons: Florencio Marco Carres Olguín (b. July 23, 951) and Teo Edgardo Carres Olguín (b. December 29, 954).

Duke of Plenas
Clemente became the ruling Duke of Plenas when his father died on June 22, 954. Strong-willed, Clemente set about ensuring his peers in the other member duchies of the Coastal Confederation saw and treated him as first among equals. To accomplish this, Clemente furthered trade beyond the region and built up a military coalition to extend confederal influence northward into the midlands and toward the Kanakan region.

When Clemente became King of Ventora, he retained his title and reign as Duke of Plenas. After his death in 972, his younger son, Teo, became reigning duke as part of treaty that ended the War of Ventoran Succession. The treaty also changed the duchy's name to Arava. This recognized the extent of its holdings beyond the municipality of Plenas and dissociated Plenas with the holdings of a duke beholden to the king.

King of Ventora
In 955, the Montañan Confederation ventured into Eshar territory and found itself overextended as a result. Haksarad saw this as an opportunity to increase its influence in southwestern Alutra and offered to constitute a kingdom incorporating the two confederations. Negotiations among the member counties continued, with Clemente's prestige growing while that of Teodosio de Montaña Pranice, Count of Ascara y Montaña, became more fragile as he sought to secure his holdings in both Esharat and the Kanakan area.

The Concords of Plenas, signed by both confederations' member counts on August 17, 959, established the Kingdom of Ventora. The name derives from the old ventosus (windy) and ora (coast) and represented the rise in power of the coastal duchies under Clemente. He was crowned as first King of Ventora, with a formal coronation on September 12, 959. Clemente ruled until his death when his eldest son claimed the throne as Florencio I. The treaty that ended the War of Ventoran Succession recognized Florencio's claim to the throne but divested him of the duchy of Arava.
