Long ago, there was a kingdom. 

Long ago, a kingdom sat on a big island. 
Many different leaders ruled the land. Some came from far away. They fought to stay in control.
Later, a new group of rulers took over. They lived on the mainland. They ruled from a city called Turin. 
This group grew very strong. They added more lands to their kingdom. They worked hard to build power.
Finally, the kingdom changed its name. It became the Kingdom of Italy. 
It is amazing how one place can change so much!
The Kingdom of Sardinia was a place in Southern Europe. It lasted from the late 1200s until the mid-1800s. 
At first, the island was part of the Spanish Empire. This began when leaders from Aragon conquered the island in 1324. They ruled for a long time. In 1720, a new group took control. This was the House of Savoy.
The Savoy rulers lived on the Italian mainland. They ruled from a city called Turin. Because of this, the island was less important to them. The kingdom grew much larger under their rule. They added lands like Liguria and Piedmont. 
By 1853, the kingdom was a strong power. The rulers added even more lands to their state. In 1861, the kingdom changed its name. It became the Kingdom of Italy. 
This new kingdom was the start of the Italy we know today. It grew from many different parts into one large nation.
The Kingdom of Sardinia was a significant state in Southern Europe. It existed from the late 13th century until the mid-19th century. 
To understand the kingdom, we must look at how it changed hands. In 1297, the Pope granted the islands of Corsica and Sardinia to King James II of Aragon. Starting in 1324, the Aragonese began to conquer the island of Sardinia. They eventually gained full control by 1420 after a long war. Later, the island became part of the huge Spanish Empire. In 1720, the island was given to the Duke of Savoy, Victor Amadeus II. This moved the kingdom into a new era of rule.
Under the Savoyard rulers, the kingdom changed its focus. The rulers lived on the Italian mainland instead of on the island. They kept their main power in the city of Turin. Because of this, the island of Sardinia was often less important to the monarchy. The state was officially called the "States of His Majesty the King of Sardinia." People often called it Piedmont-Sardinia or Sardinia-Piedmont. In 1847, a law called the Perfect Fusion centralized all government in Turin. 
As time passed, the kingdom grew much stronger and larger. After Napoleon was defeated, the Congress of Vienna gave Savoy new lands. This included a place called Liguria. By 1853, the Savoyards had built a very strong power. They added many territories through various steps. They took Lombardy in 1859 and the Two Sicilies in 1860. They also added Venetia in 1866 and the Papal States in 1870. 
These many changes led to a very big moment in history. On March 17, 1861, the kingdom changed its name completely. It became the Kingdom of Italy to match its new size. The capital moved from Turin to Florence and then to Rome. This new kingdom was the direct predecessor of the modern Italian Republic. The history of Sardinia is a key part of how Italy became a single country. 
The Kingdom of Sardinia was a major state in Southern Europe. It existed from the late 13th century until the mid-19th century. 
Long before the formal kingdom, the islands had many rulers. In 238 BC, Sardinia and Corsica became provinces of the Roman Empire. After the Romans, the Vandals occupied the islands in the mid-5th century. In 534 AD, the Eastern Roman, or Byzantine, Empire reconquered the area. By the 9th century, Arab conquests in Sicily made communication with the Byzantine capital, Constantinople, very difficult. This led to local families taking control of the land.
During the middle ages, Sardinia was organized into four small kingdoms called Judicates. These were the Judicates of Cagliari, Arborea, Gallura, and Logudoro. These local rulers, known as judges, organized themselves using ancient Roman and Byzantine models. This was called the principle of *translatio imperii*, or the transfer of rule. The island faced many threats during this time. For example, the Taifa of Denia launched a massive sea attack in 1015–16. This invasion was led by Mujāhid al-ʿĀmirī. The Judicates eventually stopped the attack with help from the fleets of Pisa and Genoa.
In 1297, a major change occurred when Pope Boniface VIII created a hypothetical kingdom. He granted the islands of Corsica and Sardinia to King James II of Aragon. The Aragonese began a conquest of Sardinia in 1324. They established actual authority through military force. By 1420, the last competing claims to the island were bought out after the Sardinian–Aragonese war. Later, the island became part of the expanding Spanish Empire.
The second major phase began in 1720. The island and kingdom were ceded to the Duke of Savoy, Victor Amadeus II. This transfer happened between the Habsburg and Bourbon claimants of the Spanish throne. The Savoyard state united Sardinia with its mainland possessions. These mainland areas included Savoy, Aosta, the Principality of Piedmont, and the County of Nice. The formal name of this complex state was the "States of His Majesty the King of Sardinia." Because the monarchy focused on the mainland, the island was often of secondary importance. 
Under Savoyard rule, the center of power moved to the mainland. While Cagliari was the official capital of the island, the city of Turin became the *de facto* seat of power. Turin had been the capital of Savoy since the mid-16th century. In 1847, a process called the Perfect Fusion centralized all government institutions in Turin. This act unified the various Savoyard states under one legal system. They also granted a constitution known as the *Statuto Albertino*. By the time of the Crimean War in 1853, the Savoyards had built a very strong power.
The kingdom grew rapidly through several annexations. In 1859, they took Lombardy. In 1860, they added the central Italian states and the Two Sicilies. They later acquired Venetia in 1866 and the Papal States in 1870.
