Mezentio was the king of Algarve. A charismatic political and military leader, Mezentio was completely ruthless in his ambition to raise Algarve to supreme power in the world and take revenge on rival powers who had humbled Algarve in earlier wars. His decision to take back the Duchy of Bari precipitated the Derlavaian War.
After a well received occupation and annexation of Bari by the people of the former duchy, Mezentio's armies had to face an alliance of the kingdoms of Forthweg, Valmiera, Jelgava, and Sibiu. Despite being badly outnumber, Algarve subdued all of their enemies. Mezentio then turned westward, and initiated a war against Unkerlant. He had earlier provoked Lagoas into entering the war when he conquered Sibiu.
Mezentio initiated the use of Kaunians to fuel his army's "Special Magecraft", ordering the deaths of thousands. His country used this method to attack Yliharma, the capital of Kuusamo, in an attempt to keep them from entering the war. Instead, he ensured their entrance.
Mezentio appointed members of his close family to rule the countries his army conquered. His brother Mainardo was made king of Jelgava, and their cousin Raniero was put on the newly reestablished throne of Grelz.
When Unkerlanter armies entered Trapani, Mezentio took up a stick and defended his palace as a common infantryman. Knowing that King Swemmel of Unkerlant intended to torture him if captured alive, Mezentio asked a number of his soldiers to kill him when his capture became imminent, and Corporal Sidroc of Plegmund's Brigade was the one who honored the request.
Mezentio appears to be named for Mezentius, an Etruscan king in Roman legend, known for his bloodthirsty nature.
- Adolf Hitler, who serves as a partial inspiration for Mezentio.
- Napoleon I of France, who serves as a secondary inspiration for Mezentio. In particular, Mezentio and Mainardo's rule of Jelgava appears to be based on Napoleon and Joseph Bonaparte's rule of Spain.
- Jake Featherston, a POV character in Southern Victory, who is also based on Hitler.
