Long ago, the Pope ruled lands. 
Long ago, the Pope ruled many lands. 
The Pope was a ruler of people. He also led the Church. The lands grew very large. They covered many parts of Italy.
Later, the lands began to change. New groups wanted to rule Italy. They took much of the land.
By the year 1870, the lands were mostly gone. Only a small part stayed. This part was inside the city of Rome.
Today, a tiny city stays with the Pope. It is called Vatican City. It is a very special place.
For a long time, the Pope was a ruler of land. 
In the 8th century, a king named Pepin the Short helped the Church. He gave lands to Pope Stephen II. This made the Pope a ruler of a real place. Before this, the Church owned some land. But now, the Pope had his own power.
At its biggest, the Papal States covered many parts of Italy. These parts included places like Lazio and Umbria. The Pope was a leader of the Church. He was also a leader of many people. 
Things began to change in the 1800s. A new group called the Kingdom of Italy wanted to rule. They took much of the land. By 1870, the Papal States were almost gone.
In 1929, a new deal was made. It was called the Lateran Treaty. This deal created Vatican City. It is a small city-state inside Rome. The Pope still rules there today.
The Papal States were a group of lands in Italy. These lands were ruled directly by the pope. This rule lasted for a very long time. It began in the year 756 and went until 1870. People often called these lands the State of the Church.
How these lands were ruled changed over many years. At first, the Church was not allowed to own property. Early Christians met in private homes to pray. Later, a law in the year 321 changed this. A leader named Constantine the Great allowed the Church to own land. The Church began to own houses and large farms.
The official start of the Papal States came from a king. His name was Pepin the Short. He was the king of the Franks. In the 8th century, he helped Pope Stephen II. Pepin gave the pope lands that were held by the Lombards. 
At its largest size, the Papal States were very big. They covered many parts of the Italian peninsula. These areas included Lazio, which contains Rome. They also included Marche, Umbria, and Romagna. Parts of Emilia were also part of the state. 

Eventually, the Papal States began to disappear. In the 1800s, the Kingdom of Italy began to form. This new kingdom wanted to control all of Italy. By 1860, they had taken most of the papal lands. 
The Papal States, also known as the State of the Church, were a collection of territories on the Italian peninsula. For over a thousand years, these lands were under the direct sovereign rule of the pope. This unique arrangement meant the pope acted as both a spiritual leader and a secular ruler. A secular ruler is someone who governs a physical country with laws and territory.
To understand how these lands were formed, one must look at how the Church acquired property. For its first 300 years during the Roman Empire, the Church was persecuted and could not own land. Early Christians met in private homes or small churches held by individuals. However, a law passed by Constantine the Great in 321 changed everything. This law allowed the Church to possess property and get back what was taken from it.
The transition from being a landowner to a sovereign ruler happened due to political shifts. As the Western Roman Empire fell, central authority disappeared. The Italian peninsula saw many different groups, like the Ostrogoths and Lombards, take control. While the popes remained spiritual leaders, they began to take on more local ruling duties. This happened because the Byzantine Empire, which technically ruled the area, could not always protect Rome from invasions.
A major turning point occurred in the 8th century with the help of the Franks. In 751, Pope Zachary helped Pepin the Short become king. Later, Pepin's successor, Pope Stephen II, gave Pepin the title of Patrician of the Romans. In response, Pepin led armies into Italy and defeated the Lombards. Between 754 and 756, Pepin gave lands to the pope, making him a temporal sovereign. 
As the centuries passed, the relationship between the popes and emperors was often complicated. Between the 9th and 12th centuries, people debated if the Papal States were independent or part of the Frankish or Holy Roman Empires. There were many disagreements over who held true authority. 
At its peak, the Papal States covered a massive amount of territory. The state included most of the modern Italian regions of Lazio, Marche, Umbria, and Romagna. It also included parts of Emilia. 
The end of the Papal States came during the movement to unify Italy. Between 1859 and 1870, the Kingdom of Italy was formed through a process of unification. By 1860, most of the papal lands had been conquered by this new kingdom. By 1870, the pope held only the Leonine City within Rome.
