Edward III (November 13, 1312 – June 21, 1377). The seventh King of England of the Plantagenet Dynasty (reigned from 1327 to 1377), who initiated the Hundred Years War and dealt a huge blow to France.
Another major hostile target during the reign of Edward III was Scotland. As early as 1333, Edward III defeated Scotland in the Battle of Harrington Hill. In 1356, he once again entered southern Scotland.
Edward III was one of the most feared kings of England. For over 30 years, he has consistently demonstrated demonic vitality. After eliminating Mortimer, Edward quickly established his reputation among other nobles and reached the pinnacle of power at the age of twenty five or six. He is very tall, good-looking, with a thin and long nose, a pointed yellow beard, and a long drooping beard. According to people at the time, his face was "like the face of God.". He is noble and dignified. Charming. Speaking English is as good as French, with a gentle and soothing voice. He is extremely elegant and noble, treats friends with great enthusiasm, and treats enemies with a heart of stone. At the same time, he is prone to self indulgence and indulging in women, which ultimately harms his health. In the last decade of his rule, he suffered a stroke, leading to a reversal of the situation in England and France. It was also at this time that the Roland Reformation movement, which was considered heretical, flourished.

Edward III was the son of the murdered tyrant Edward II, born in Windsor, Berkshire. After her mother Isabelle of France conspired with her lover Roger Mortimer, the first Earl of March, to depose Edward II, she became the actual ruler of England. The Earl of March gained a large number of fiefdoms (including the famous Dombey fiefdom) and dominated England.
After his father was deposed in February 1327, Edward III was crowned King of England by the Archbishop of Canterbury, Walter Reynolds (one of Edward II's favorites). Real power was held by the regent empress dowager and her lover Count March. However, Edward III quickly gathered his strength to punish those who had killed his father. In 1330, Edward III came to power and immediately ordered the execution of Roger Mortimer and the confiscation of his property (but in 1348, he re awarded the title of Count March to Roger Mortimer's grandson).

In 1332, Edward III sent troops to support Scottish exiled nobleman Edward Barrio, achieved victory in the Battle of Dublin, and proclaimed himself king in Stirling, Scotland. However, the new king, like his deposed father, was unpopular. The Homecoming Corps found that they continued to face consistent isolation and hostility. In December, they were attacked by forces still loyal to the Bruce family in Annan, causing heavy losses and had to flee the River Tweed to seek refuge from the English.
In 1333, Edward III personally led his army to support and defeated the Scottish army in the Battle of Harrington Hill. Barrio's power reached its peak and his sphere of influence reached a larger area in eastern Scotland. In early 1334, Bario signed a treaty with England to cede eight counties in Scottish territory. Edward III then generously ceded these eight counties to Barion, but acquired these lands as English nobles rather than Scottish kings.
After the content of the agreement was exposed, the resistance of Scottish nobles and the people against the Barion regime increased dramatically. In 1334, the third Earl of Murray, John Randolph, returned from France to Scotland to lead military operations, and the situation began to change. In September, Barrio withdrew from Scotland and took refuge in England.
Barrio returned to Scotland several times in the following years, but each time he followed the English army. His own puppet nature is also evident, and even in the stationed fortress, the command of the army is firmly held in the hands of English noble officers, while this "King of Scotland" has no authority. In areas that the English army could not defend, they completely did not recognize Barion and still supported the young king David II in France.
In 1337, the Hundred Years' War broke out between England and France, and England had no power to organize a large army into Scotland, causing Bario to lose power.

In 1336, in retaliation for King Philip VI's invasion of British merchants in Flanders, Edward III ordered a ban on exporting wool to France. Due to dissatisfaction with Philip VI's succession to the French throne (Edward was the nephew of Charles IV, the last king of the Capetian dynasty), Edward III harbored increasing hostility towards France. In 1337, Edward III officially proclaimed himself as the King of France, and thereafter until 1801, every English king also claimed to be the King of France. He immediately joined forces with Holy Roman Emperor Louis IV to assemble an anti French force. When Philip VI announced the confiscation of all his territories in France in 1338, Edward's anger erupted. In 1339 and 1340, he launched two failed offensive attempts from northern France; In June 1340, the British fleet achieved a complete victory in the Battle of Sluis. But the excessive military spending made it impossible for Edward III to sustain the war. In 1344, he even declared bankruptcy, leading to the collapse of two large banks in Florence. In 1346, Edward III and his eldest son, Prince Edward, made a comeback and defeated the French army in the Battle of Cresi. This battle marks the first appearance of the outstanding general, Prince Edward of Black. By 1347, Edward III had captured the important French town of Calais and was preparing to advance to Paris for coronation. In 1348, he refused the invitation to run for the Holy Roman Emperor.
In 1356, the British army once again achieved a great victory in the Battle of Poitiers and captured King John II of France. Edward III signed the Treaty of Calais with various intentions of the French nobility, controlling large territories in northern France but promising to renounce the French throne.
In 1359, Edward III invaded France again, besieging Reims, and then advancing further to Paris; There, he signed the Treaty of Brittany with the French Regent Prince Charles (later King Charles V). In 1360, he conferred the title of Duke of Aquitaine on Prince Edward of France.
After Charles V officially ascended the throne in 1364 and refused to recognize the Treaty of Calais, Edward began to use the title of King of France again. But Charles V was a difficult opponent to deal with, and he took many powerful reform measures. At the same time, in France, excellent generals such as Di Guerlain (Bertrand Du Guerlain) emerged. Edward III's war plan began to fail from then on. His expansion activities have come to an end.

In 1348, England under the rule of Edward III suffered one of the greatest disasters in history - the Black Death. He issued some laws to force people to continue working. In 1353, the English Parliament passed a bill prohibiting citizens from appealing to church courts and paying tithes to the Pope. Around 1348, Edward III founded the Knights of Gard.
Edward III was a wise ruler, but suffered a stroke in the last ten years of his reign, becoming unconscious in his later years and under the control of his mistress, Mrs. Perez. It was also at this time that the Roland Reformation movement, which was considered heretical, flourished.

Edward III's most famous military achievement was the opening of the Hundred Years' War, which led to the seizure of a large amount of land from France.
Another major hostile target during the reign of Edward III was Scotland. In 1333, Edward III defeated Scotland in the Battle of Harrington Hill. In 1356, he once again entered southern Scotland.
