1. Trần Khánh Dư (1240 - 1340)
Trần Khánh Dư, known by the title Nhân Huệ Vương, was a statesman and military leader during the Tran Dynasty. Although he belonged to the Trần family, he did not come from royal lineage. His father, Trần Phó Duyệt, was a high-ranking general, and they hailed from Chí Linh, Hải Dương.
During the first Mongol invasion of Vietnam in 1258, Trần Khánh Dư played a pivotal role in ambushing the enemy forces, leading to a decisive victory. He later fought against the Man people in the mountains. Due to these achievements, he was honored by the Tran Emperor, being adopted as a foster son (Thiên Tử Nghĩa Nam), granted the title Nhân Huệ Vương, and appointed as the Phiêu Kỵ Đại Tướng Quân. This rank was usually reserved for royal family members, but Khánh Dư's special status allowed for this rare distinction.
However, despite his military success, Trần Khánh Dư fell into disgrace when he was accused of an affair with Princess Thiên Thụy, wife of Trần Quốc Nghiễn (son of General Trần Quốc Tuấn). This scandal resulted in him being punished by the Emperor. Though he was severely beaten, he survived the ordeal, thanks to a secret order from the Emperor to spare him. He was stripped of his rank and sent back to his homeland to live a humble life selling coal.
In 1282, facing the imminent threat of a second Mongol invasion, Trần Khánh Dư was pardoned by the Emperor and invited to participate in the Bình Than Conference. His strategic proposals were well-received and helped shape Vietnam's defense. Trần Khánh Dư also played a crucial role in destroying 70 Mongol supply ships led by Trương Văn Hổ in Vân Đồn at the end of 1287, significantly shifting the balance of the war.
In May 1312, he led the army in a campaign against Champa, capturing the Champa King, Chế Chí. In 1323, he retired to his estate in Dương Hòa, Hà Nam, and passed away in 1340 at the age of 100.

2. Phạm Ngũ Lão (1255 - 1320)
Phạm Ngũ Lão was a renowned general during the Tran Dynasty, hailing from Phù Ủng village, Ân Thi district, Hưng Yên province. He was the great-grandson of the famous general Phạm Hạp.
From a young age, Phạm Ngũ Lão exhibited extraordinary intellect and ambition. One day, while weaving a basket on the street and absorbed in studying the military text 'Binh Thư,' he failed to notice a military procession led by Hưng Đạo Vương Trần Quốc Tuấn. A soldier, trying to get his attention, shouted at him and even pricked his thigh with a spear, but Phạm Ngũ Lão remained motionless, completely focused. Recognizing his potential as a future military leader, Trần Quốc Tuấn ordered the soldiers to tend to his wound and bring him to the court. Once in the capital, Phạm Ngũ Lão was appointed as the commander of the Imperial Guard.
He played a key role in both the second and third Mongol invasions. During the second invasion, he worked alongside Trần Quang Khải to defeat the Mongol navy at Chương Dương and Hàm Tử. In the third invasion, he was instrumental in ambushing the Mongol retreat along the Bạch Đằng River and later pursued the retreating forces on land.
In 1290, King Trần Nhân Tông promoted Phạm Ngũ Lão to the position of Hữu Kim Ngô Đại Tướng Quân. In 1294, after his successful campaign against the Lao forces, he was awarded the Golden Seal (Kim Phù). During the reign of King Trần Anh Tông, he was further promoted to the rank of Điện Súy Thượng Tướng Quân and given the title Quan Nội Hầu. Phạm Ngũ Lão passed away in 1320 at the age of 66.

3. Trần Quốc Toản (Birth and death dates unknown)
Trần Quốc Toản was a member of the Tran royal family, living during the reign of King Trần Nhân Tông. He is best known for his contributions during the second Mongol invasion and his heroic death, which became legendary. His story is seen as an embodiment of bravery and unwavering resolve, showcasing the courage of a young man who faced foreign invaders.
In 1282, when the threat of another Mongol invasion loomed, King Trần Nhân Tông convened the Bình Than conference to strategize with his royal officials and generals. Despite their youth, Trần Quốc Toản and Hoài Nhân Vương Kiện were excluded from the meeting. Frustrated and embarrassed, Trần Quốc Toản crushed a fruit in his hand, vowing to take action. He returned home, mobilized over a thousand of his relatives and servants, and equipped them with weapons and ships. He also created a flag emblazoned with the words, "Defeat the mighty enemy, repay the king’s grace."
In May 1285, King Trần Nhân Tông sent Trần Quốc Toản, Chiêu Thành Vương, Hoài Văn Hầu, and General Nguyễn Khoái to confront the Mongol army at Tây Kết (Khoái Châu, Hưng Yên) and achieved victory.
There is little historical record of his death, with the Đại Việt Sử Ký Toàn Thư being the only source that mentions it, stating that King Trần Nhân Tông was deeply saddened by his loss and composed a memorial eulogy, posthumously granting him the title of 'Vương' (Prince).
Trần Quốc Toản's legacy lives on in Vietnam’s history as a symbol of patriotism, bravery, and sacrifice for the nation’s independence and freedom.

4. Nguyễn Khoái
The birth and death dates of Nguyễn Khoái remain unknown, but historical records confirm that he was a prominent general from Hải Dương, serving under Emperor Trần Thánh Tông and King Trần Nhân Tông. He played a vital role in both the second (1285) and third (1288) Mongol invasions.
During the second invasion in 1285, Nguyễn Khoái was entrusted with leading the elite Thánh Dực troops, tasked with protecting Emperor Trần Thánh Tông and King Trần Nhân Tông, while also carrying out any combat orders given. In May 1285, Nguyễn Khoái, along with generals Trần Nhật Duật, Chiêu Thành Vương, and Trần Quốc Toản, led a successful defense at Hàm Tử and Tây Kết, securing a major victory. In this battle, Nguyễn Khoái’s wife tragically lost her life, and the local people later built a shrine in her honor.
In 1288, during the third Mongol invasion, Nguyễn Khoái participated in the decisive battle on the Bạch Đằng River. His Thánh Dực forces were assigned the task of splitting the Mongol fleet, a mission they executed flawlessly. His naval forces struck fear into the Mongol soldiers, who scrambled to defend themselves while trying to flee.
Following the war, the king honored the generals for their bravery, and Nguyễn Khoái was granted the title Liệt Hầu and a fief in Khoái Châu, Hưng Yên. This was a rare distinction, as he was not from the royal family but was still awarded such a prestigious title.
Today, his name is immortalized in Vietnam, with streets named after him, including Nguyễn Khoái Street in Hanoi’s Hai Bà Trưng district and in Ho Chi Minh City’s District 4.

5. Trần Quốc Tuấn (? - 1300)
Trần Quốc Tuấn, a distinguished politician, military leader, and royal family member during the Tran dynasty, was the son of Khâm Minh Đại vương Trần Liễu, the elder brother of King Trần Thái Tông. This made Trần Quốc Tuấn the nephew of King Trần Thái Tông. Described by history as exceptionally intelligent, he made notable contributions in both politics and military affairs.
During the first Mongol invasion of 1258, he was appointed by King Trần Thái Tông to lead the forces defending the border against the invaders. Afterward, he retired to his estate in Vạn Kiếp.
In October 1283, when the Mongols prepared for their second invasion, King Trần Thánh Tông and King Trần Nhân Tông appointed Trần Quốc Tuấn as National General (Quốc công tiết chế), commanding the entire Vietnamese army.
In 1285, he led the Vietnamese forces to repel the Mongol invasion under General Toa Hoan. After initial setbacks, the Vietnamese forces, under the leadership of the two kings and Trần Quốc Tuấn, launched a successful counteroffensive, defeating the Mongols in the battles of Hàm Tử, Chương Dương, Trường Yên, and Vạn Kiếp, driving them out of the country.
In 1288, when the Mongols returned for a third invasion, Trần Quốc Tuấn was again appointed by the kings to lead the national defense. When asked by the king, “What should we do about the invaders?” Trần Quốc Tuấn confidently replied, “This year, fighting the enemy will be easy.”
He employed a tactic from the Battle of Ngô Quyền, decisively defeating the Mongol navy led by Ô Mã Nhi and Phàn Tiếp in the Battle of Bạch Đằng River. He then led a fierce counterattack, crushing the Mongol infantry and cavalry under General Toa Hoan as they attempted to retreat by land.
In April 1289, King Trần Nhân Tông formally granted him the title of Đại Vương (Great King). However, the actual power in the court still rested with Chiêu Minh Vương Trần Quang Khải. During his lifetime, Trần Quốc Tuấn authored influential military texts such as Hịch Tướng Sĩ, Binh Thư Yếu Lược, and Vạn Kiếp Tông Bí Truyền Thư, which motivated his troops and outlined advanced military strategies.
He later retired to Vạn Kiếp and passed away in 1300. After his death, the court posthumously honored him with the title “Thái Sư Thượng Phụ Thượng Quốc Công Nhân Vũ Hưng Đạo Đại Vương.” He was venerated by the people as “Đức Thánh Trần” (Saint Trần), and many temples were built in his honor, with the most famous being the Kiếp Bạc Temple in Hưng Đạo, Chí Linh, Hải Dương.

6. Trần Quang Khải (1241 – 1294)
Trần Quang Khải was a notable politician, military leader, and royal family member during the Tran dynasty. He was the third son of King Trần Thái Tông and the younger brother of King Trần Thánh Tông. By blood, he was the nephew of Trần Quốc Tuấn, whom he would refer to as his older cousin.
From a young age, Trần Quang Khải was appointed by his father as Chiêu Minh Vương. In 1258, King Trần Thánh Tông elevated him to Chiêu Minh Đại Vương, and in 1261, he was appointed as Thái Úy (Grand General). By 1265, he was promoted to Thượng Tướng (Senior General) and assigned to defend Nghệ An. In early 1271, he was made Tướng Quốc Thái Úy, a position above that of Hưng Đạo Vương Trần Quốc Tuấn.
Trần Quang Khải played a pivotal role in the second Mongol invasion of Vietnam. In February 1285, Toa Đô's forces attacked Nghệ An. Although Trần Nhật Duật initially resisted the invasion, reinforcements led by Trần Quang Khải arrived too late to prevent the enemy's victory.
After capturing Nghệ An, Toa Đô advanced towards Thanh Hóa. Trần Quang Khải, along with local commanders and the people of Thanh Hóa, mounted a fierce defense to protect their villages and block the enemy’s progress. However, due to the overwhelming strength of the Mongols, he was forced to retreat temporarily.
In May 1285, under the supreme command of Quốc Công Tiết Chế Trần Quốc Tuấn, Trần Quang Khải, along with Chiêu Văn Vương Trần Nhật Duật and other generals, led a counteroffensive to the north. Trần Quang Khải and Trần Nhật Duật were tasked with attacking Mongol fortifications along the banks of the Red River. Trần Quang Khải personally led the assault on Chương Dương (located in Thường Tín, Hanoi, on the right bank of the Red River, across from Hàm Tử).
The historical records are unclear regarding Trần Quang Khải’s role in the third Mongol invasion in 1288. After the war, he resumed his position as Tướng Quốc Thái Úy and continued to manage the affairs of the state.

7. Trần Nhật Duật (1255 – 1330)
Trần Nhật Duật, known as Chiêu Văn Vương, was a prominent political and military figure during the Tran dynasty. He was the sixth son of King Trần Thái Tông and the younger half-brother of King Trần Thánh Tông and Chiêu Minh Đại Vương Trần Quang Khải. He was also the maternal brother of Chiêu Quốc Vương Trần Ích Tắc and Chiêu Đạo Vương Trần Quang Xưởng.
Despite his royal background, Trần Nhật Duật led a simple, humble, and generous life, gaining respect for his approachable and tolerant nature. He was well-versed in the languages and cultures of neighboring countries such as Song, Ai Lao, and Champa, and made significant contributions to the cultural development of Đại Việt, particularly in literature, music, and language.
He played a crucial role in the second (1285) and third (1288) Mongol invasions, particularly in the victory at Hàm Tử (located in Khoái Châu, Hưng Yên). His success at Hàm Tử paved the way for the later victory at Chương Dương, which was led by famous generals Trần Quang Khải and Trần Quốc Toản in 1285.
In 1302, King Trần Anh Tông appointed him as Thái Úy Quốc Công to assist with the governance of the state. King Trần Anh Tông held him in high regard and often sought his counsel on state affairs.
In 1324, King Trần Minh Tông promoted Trần Nhật Duật to Tá Thánh Thái Sư. Later, in 1329, after ascending the throne, King Trần Hiến Tông elevated him to the title of Chiêu Văn Đại Vương.
Trần Nhật Duật passed away in 1330 at the age of 75.
