The Italian War of 1551–1559 was a big conflict in Europe. It is also known as the Habsburg–Valois War or the Last Italian War. It began in 1551 when Henry II of France declared war on Emperor Charles V. Henry II wanted to take back parts of Italy. He also wanted France, not the Habsburg family, to be the most powerful in Europe.
The war ended in 1559 with the Treaty of Cateau-Cambrésis. This treaty was signed by the leaders of Spain, England, and France. During this war, new gunpowder weapons and stronger forts were very important. Soldiers also became more professional.

How the War Was Fought
Fighting in the Mediterranean Sea

Henry II of France made a special deal with Suleiman the Magnificent, the leader of the Ottoman Empire. They agreed to work together against the Habsburgs in the Mediterranean Sea. This alliance helped France attack areas near the Rhine River. Meanwhile, a combined French and Ottoman fleet protected southern France.
In 1551, Ottoman forces attacked Tripoli. French ships from Marseille joined the Ottoman fleet. In 1552, when Henry II attacked Charles V, the Ottomans sent many ships. These ships, along with three French ships, raided the coast of Southern Italy. They captured the city of Reggio.
Later, in the Battle of Ponza, the French and Ottoman fleet defeated the Genoese ships. This alliance also led to the combined invasion of Corsica in 1553. The Ottomans kept attacking Habsburg lands in the Mediterranean. One example is the Ottoman invasion of the Balearic Islands in 1558, which Henry II had asked for.
Fighting on Land
The War of Parma
The war started on land because of a problem in Parma. The new Pope, Pope Julius III, said Ottavio Farnese was the rightful Duke of Parma. But Charles V's troops had taken over the city in 1547. Ottavio Farnese decided to ally with Henry II of France in May 1551. France would protect Parma.
Charles V did not like this. He convinced the Pope to join him against France and Parma. This started the War of Parma in June 1551. A key battle was the Siege of Mirandola (1551). French and Parma defenders successfully fought off attacks from the Pope's, Emperor's, and Spanish forces. A two-year truce ended this part of the war in April 1552.
German and Sienese Conflicts
Henry II also made a deal with German Protestant princes in 1552. This was the Treaty of Chambord. France successfully attacked Lorraine. Henry captured the cities of Metz, Toul, and Verdun. He kept them by defeating the Habsburg army at the Battle of Renty in 1554.
In 1552, people in the Republic of Siena rebelled against Spain. Henry II gained another ally. A French and Sienese army kicked out the Spanish soldiers. Siena welcomed French troops to protect them. In 1553, a French army went into Tuscany to help Siena.
In January 1554, the Spanish began to surround Siena. The French troops were attacked by an army from the Emperor and Florence. They were defeated at the Battle of Marciano in August 1554. After a long siege, Siena fell to Spanish forces in April 1555. The land of Siena later became part of the Duchy of Florence in 1559.
Papal States and St. Quentin
A peace deal was signed in 1556 between Charles V and Henry II. But it did not last long. After Charles V gave up his power, his empire was split. Philip II of Spain became King of Spain. Ferdinand I became Holy Roman Emperor. The war then focused on Flanders.
Pope Paul IV was unhappy and asked Henry II to join him in attacking Spanish Naples. In September 1556, Philip II attacked the Papal States first. French forces coming from the north were defeated at the Siege of Civitella in August 1557. Philip, with the help of Emmanuel Philibert, Duke of Savoy, defeated the French at the Battle of St. Quentin (1557) in August 1557.
The Spanish tried to block Rome by taking over the port of Ostia. But the Papal armies pushed them back. When French troops could not help, the Papal armies were defeated. Spanish troops reached the edge of Rome. To avoid another attack on Rome, Pope Paul IV agreed to a peace deal. The Papal States became neutral in September 1557.
England Joins and Gravelines
A small rebellion in England, supported by France, led to England joining the war. Queen Mary I declared war on France in June 1557. English troops helped win the battle at St. Quentin. But England's entry into the war led to the French Siege of Calais in January 1558. This was a big defeat for England.
French armies attacked Spanish lands in the Low Countries. They also won the Siege of Thionville in 1558. However, Henry II lost badly at the Battle of Gravelines in July 1558. This forced him to agree to a peace deal. He gave up any claims to Italy.
The war ended for other reasons too. Both Spain and France ran out of money in 1557. Also, Henry II had to deal with a growing Protestant movement in France. He wanted to stop it.
Treaty of Cateau-Cambrésis (1559)
What the Treaty Did
The Treaty of Cateau-Cambrésis (1559) was actually two treaties. The first was signed by Elizabeth I of England and Henry II of France on April 2. The second was signed by Henry II of France and Philip II of Spain on April 3. These treaties officially ended the wars between the Emperor and France. They also ended the long conflict between the Habsburg and Valois families. The leaders did not meet in person. Instead, their representatives signed the agreements.
What Happened After the War
After the war, there were some important marriages. Emmanuel Philibert, Duke of Savoy married Margaret of France, Duchess of Berry, who was Henry II's sister. Philip II of Spain married Elisabeth, Henry II's daughter.
During a tournament to celebrate the peace, King Henry II was badly hurt. On July 1, a piece of a broken lance went into his eye and brain. He died ten days later, on July 10, 1559. His 15-year-old son, Francis II, became king. But he also died soon after, in December 1560. His 10-year-old brother, Charles, then became king.
This caused a lot of political problems in France. Many soldiers were also out of work and not paid. These issues led to the start of the French Wars of Religion in 1562. These wars would last for the next thirty years in France.
After the war, Italy was divided. The Spanish Habsburgs ruled in the south. The Austrian Habsburgs had control in the north. Different families ruled other areas, like the Medici in Tuscany and the House of Savoy in Piedmont. The Pope kept a lot of cultural and political power in central Italy.
This situation in Italy lasted until the 1700s. Then, northern Italy went to the Austrian Habsburgs. Southern Italy went to the Spanish Bourbons.
