Long ago, there was a leader. 
Long ago, a leader named Ramon Berenguer lived. 

Ramon Berenguer IV was a leader from long ago. 

This marriage joined two lands together. They formed the Crown of Aragon. This union made the lands safer. It also gave Aragon a way to reach the sea. Ramon was a brave leader. He led many battles. He helped win cities like Tortosa and Lleida. He also helped in a holy war called a Crusade.
In 1151, he built a monastery called Poblet. He was known as a wise and noble man. He had a strong body and a bright mind. He died in Italy in 1162. His son took over his lands. His son became Alfonso II of Aragon. This helped the new lands stay strong for a long time.
Ramon Berenguer IV was a very important leader in the Middle Ages. He was the Count of Barcelona and a prince of Aragon. 
His rise to power happened through a special marriage plan. Ramon was born around the year 1114. He became the Count of Barcelona in 1131 after his father died. In 1137, he was promised to a one-year-old girl named Petronilla. She was the princess of Aragon. Her father, King Ramiro II, stepped away from public life. This left Ramon and Petronilla to rule their lands together. They made a deal so their children would rule both lands.
This plan was a very smart political move. The two lands kept their own laws and ways of doing things. They stayed separate but worked together as one family. 
Ramon was also a very active leader in many battles. He took part in the Second Crusade in 1147. He helped conquer the city of Almería in October of that year. Later, he captured the city of Tortosa in December 1148. He did this after a long siege of six months. His army also took the cities of Fraga, Lleida, and Mequinenza in 1149. These cities were near the Segre and Ebro rivers.
People described Ramon as a very noble and brave man. He was known for having a steady mind and a lively spirit. He even helped lead Provence for many years. 
Ramon Berenguer IV was a powerful ruler during the Middle Ages. He was the Count of Barcelona and a prince of Aragon. 
His rise to power began with his birth around 1114. He was the son of Count Ramon Berenguer III and Countess Douce I of Provence. On August 19, 1131, he inherited the County of Barcelona from his father. 
This political arrangement was very complex. Ramon Berenguer was the ruler of Aragon in practice. However, he was never officially a king. He acted as a prince-consort instead. He used titles like "Count of the Barcelonans and Prince of the Aragonians." 
This union was a major political masterstroke. The two realms remained legally distinct. They kept their own laws, institutions, and autonomy. They were federated under one ruling house instead. This allowed both lands to gain strength and security. Aragon specifically gained a much-needed outlet to the sea. 
During his rule, Ramon Berenguer engaged in many military campaigns. He fought against the Moors during the middle years of his reign. In October 1147, he joined the Second Crusade. He helped the kingdom of Castile conquer the city of Almería. He also invaded the Almoravid taifa kingdoms of Valencia and Murcia. 
His military success continued into the following year. In 1149, his army captured several important cities. These included Fraga, Lleida, and Mequinenza. These locations were at the confluence of the Segre and Ebro rivers. Ramon Berenguer also spent time in Provence. He helped his brother, Berenguer Ramon, and his nephew. Between 1144 and 1157, he acted as the regent of Provence. In 1151, he signed the Treaty of Tudilén with Alfonso VII. This treaty helped define conquest zones in Andalusia to prevent conflict. That same year, he founded the royal monastery of Poblet.
Historical records describe Ramon Berenguer's character in detail. The Chronicle of San Juan de la Peña called him a man of great nobility. It said he possessed prudence, probity, and a steady intellect. He was described as having a lively temperament and great bravery.
