Lý Cao Tông

At that time, the affairs of the state were abandoned. Civil belief was replaced by disgust. Many revolts and secessions exploded amongst the peasantry and small local nobles. The court tried to suppress the rebellions, but it was to no actual effect.

In 1192, the civilians from Cổ Hoằng, Thanh Hóa rioted. The rebellions of Câu Diễn and Đinh Khả followed in 1198, who professed to be the descendants of Đinh Tiên Hoàng.

In August 1203, the king of Champa, Vidyanandana, entered Cửa Lò seeking asylum from a Khmer invasion. Vidyanandana killed the governor of Nghệ An, Pham Gieng. Vidyanandana then fled, never to be heard from again.[4]^: 79–80

There was a potent force rebelling in September 1203 under the leading of two people from Đại Hoàng River. Many years ago they had accused Đàm Dĩ Mông of bleeding monetary and civil property. They used the turbulent society and lack of a central power to establish a force to oppose the court. All generals sent to suppress them failed. The first generals were Trần Lệnh Hinh and Từ Anh Nhữ, a minister, who were both killed, and the last general was Đỗ Kính Tu.

In 1207, in the mountainous area of Tản Viên ( now Hà Tây ) there has a revolt of some minorities, which was quite prestigious.

In addition to the internal conflict and constant hunger during this time, the Song dynasty invaded with their Northern Army and the Vietnamese living in the areas tried to flee.

March 1207, two squires in Hồng Châu area ( now Hải Dương and Hải Phòng) Đoàn Thượng and Đoàn Chủ rioted, built fortifications, and conferred the title Lord on themselves. Cao Tông dispatched a great number of soldiers, dividing them on some corps to suppress the rebellion. There were 4 main corps from 4 directions: the Đại Thông corps of Đàm Dĩ Mông, the Khả Liễu corps of Phạm Bỉnh Di, the Phù Đái corps of Trần Hinh, the Nam Sách corps of Bảo Trinh; they all would assemble to suppress Đoàn Thượng's army. Recognizing that confronting Du with such a large army would kill them all, Thượng bribed Du with costly furniture and willingly followed him, establishing a coalition between Du and Thượng. Thanks to Du's efforts to implore Cao Tông for forgiving Thượng, Thượng saved his neck.

Du went to Nghệ An to manage the army in 1209. This province underwent a catastrophic starvation whereby a large number of people died of hunger. The survivors left their homes and wandered, penniless. Most of them became beggars. Hence Phạm Du told the king that: "The society now is chaotic, and the pillaging and the rebellions are uncontrolled. Please allow me to recruit soldier for establishing a self-defense army ...."

Cao Tông agreed with him. Du recruited the local people to blockade the transport system, both on land and water. Cao Tông identified his army as rebellious and sent Phạm Bỉnh Di with an army from Đằng Châu Hưng Yên to conquer him. Du retreated to Cổ Miệt and united with the army of Đòan Thương and Đoàn Chủ from Hồng Châu. Pham Bỉnh Di was defeated in Đằng Châu. In February 1209, Bỉnh Di fought again with an army from Đằng Châu and Khoái Châu and defeated Du, who fled in retreat. He confiscated all of Du's property and set it on fire.

Đoàn Thượng's army was overthrown in April 1209. Phạm Du bribed high-ranking officials in the capital and accused Bỉnh Di of a ferocious massacre. Cao Tông allowed Trần Hinh to convoke Phạm Du to come to the court and also called Bỉnh Di back. Phạm Du returned to the capital first and told the king false rumors about Bỉnh Di. When Bỉnh Di arrived, Cao Tông sent both him and his son to prison.

After being told of Bỉnh Di's imprisonment, one of his subordinates named Quách Bốc led his army to the Đại Thanh Gate of the citadel and overthrew it to save *. . Phạm Du and Phạm Kinh killed Bỉnh Di and his son and then escaped the citadel with Cao Tông.

Quách Bốc occupied the citadel and enthroned the young prince Lý Thầm. Cao Tông fled to Tam Nông, Phú Thọ and lodged at the residence of Hà Vạn, who was a minority leader holding a substantial force. The Crown Prince Sảm, who later became the succeeding king Lý Huệ Tông, fled to Hải Ấp, Thái Bình with his mother, Noble Consort Đoàn and his two younger sisters. Sảm stayed at the residence of Trần Lý and married his daughter Trần Thị Dung. Then he conferred the title Minh Tự on Trần Lý, and the title Commander of Anterior Citadel on Trần Lý's brother-in-law Tô Trung Từ. Lý Thái Tổ also held the title of Commander of the Anterior Citadel during the time he was an official of the Anterior Lê dynasty ). They recruited soldiers from the surrounding area and fought against Quách Bốc.

When that Lý Sảm established his own court and arbitrarily conferred titles, Cao Tông sought to suppress his military power. He sent Phạm Du to associate with Đoàn Thượng, but Du missed the meeting with Đoàn Thượng because he spent time with the Princess Thiên Cực. Du was killed by the army of the landlord of Bắc Giang when crossing over Ma Lãng to go to another meeting.

Trần Lý and Tô Trung Từ led their army to the capital to defeat Quách Bốc. At the end of 1209, they suppressed the rebellion Cao Tông was once again king. Trần Lý died in battle. Because Phạm Du was dead and Tô Trung Từ held the most power in the court, Cao Tông was forced to work with him. Even though Đàm Dĩ Mông worked with the rebel Quách Bốc when he occupied the citadel, he became the Thái úy – a rather high official.

There is no document confirming how Quách Bốc and Lý Thầm died.
