Papal States

Lore & Background

In the world of Europa Universalis IV, the Papal States are the earthly seat of the Roman Catholic Church. The Pope rules not merely a patchwork of Italian provinces but the conscience of half the map. Every Catholic nation looks to Rome for spiritual legitimacy, and every heretic nation fears the weight of a Papal Bull. The Papal States exist in a paradox: a theocratic state that must maintain a standing military, collect taxes, and navigate the same diplomatic webs as any other power, yet whose true authority is spiritual rather than merely territorial. The game captures the historical tension between the Pope's temporal ambitions and his spiritual duties. The Papal States can expand, build armies, and pursue trade, but their national identity is inextricably bound to the Church. Their national ideas reflect this duality—some grant military and economic power, while others reinforce the Pope's unique role as head of the Catholic faith. The Conclave mechanic, in which Cardinals vote to select a new Pope upon the death of the current one, adds a layer of internal political drama unique to this nation. As the game progresses through the 15th, 16th, and 17th centuries, the Papal States confront the Reformation, the rise of Protestantism, the Sack of Rome, and the slow erosion of their temporal power. The fall of the Papal States to the unification of Italy in the late 19th century is one of the game's most poignant historical endings, transforming a once-dominant power into a rump state confined to the Vatican.

In Their Own Story

The morning light catches the gold leaf on the papal tiara as it rests on the velvet cushion before the throne. Outside the windows of the Vatican, the bells of Rome ring in unison, their bronze voices rolling over the Tiber and into the narrow streets where merchants are already calling their wares. The Pope rises from the chair of state, his white robes catching the candlelight, and turns to face the assembled Cardinals in the conclave chamber. "Brothers," he says, and the word carries the weight of every Pope who has spoken it before him, "the faith is wounded. The heretics in the north multiply. The faithful look to us and find only silence." He pauses, letting the silence fill the room like incense smoke. "We will not be silent. We will call the war. We will name the target. And every Catholic sword in Christendom will answer." The Cardinals murmur among themselves, the rustle of their robes the only sound in the vast chamber. The Pope watches them, patient as the city outside, eternal as the stone walls of Rome itself.

Reader's Guide

The Papal States use the Theocracy government type, which grants modifiers such as reduced religious conversion resistance and unique theocratic bonuses, while imposing restrictions like the inability to be a vassal or subject of another nation. The Pope is the sole ruler type, and succession occurs through the Conclave, where Cardinals vote from a candidate pool. The 15 national ideas are grouped into three sets of five. Set 1 centers on the Pope's spiritual authority: ideas covering Papal Authority (prestige and diplomatic weight), the Catholic Church's institutional influence, Infallibility (reinforcing the Pope's doctrinal authority), the ability to call a Holy War designating a target for all Catholic nations, and Indulgences (economic and trade benefits tied to the Church's financial mechanisms). Set 2 focuses on the Papal institution itself: Papal Bull (diplomatic and religious powers including excommunication), the Conclave (affecting the succession process), the Papal Guard (military bonuses reflecting the Swiss Guard), the Vatican (a general institutional bonus), and Catholic Doctrine (faith-related modifiers). Set 3 addresses the temporal state: Papal Decree (administrative and legal powers), Sovereignty (reinforcing the Papal States' independent status), Papal Revenue (economic income from tithes and Church lands), the Eternal City (bonuses tied to Rome as capital), and the Apostolic See (a broad institutional bonus). Key unique mechanics include: calling a Holy War (designating a target that all Catholic nations can join), excommunicating a nation (imposing penalties), issuing Papal Bulls, and the Conclave succession system. The Papal States do not have a unique trade company or a unique colonial type. Notable in-game events include the Reformation crisis, the Sack of Rome, the Counter-Reformation, and the eventual loss of temporal territory to the unification of Italy, which reduces the Papal States to a small state around the Vatican.

Did You Know?

• The Papal States is the only nation in Europa Universalis IV whose ruler is selected through a Conclave, with Cardinals voting from a pool of candidates rather than inheriting the throne.
• The Pope can designate any nation as the target of a Holy War, allowing all Catholic nations to join a single coordinated military campaign—a mechanic unique to the Papal States.
• The Papal States cannot be made a vassal or subject of another nation, reflecting the historical principle that the Pope answers to no earthly sovereign.
• The fall of the Papal States to Italian unification in the late 19th century is one of the game's most dramatic historical endings, reducing a once-majestic power to a tiny state around the Vatican.
