Dai Viet (Mighty Dai Viet Empire)

Daiviet (Daivietian: 大粤) is a constitutional monarchy in Southeast Asia. It is bordered by China to the north, Siam to the southwest and the South China Sea (known as "East Sea") to the east. It is one of the most developed countries in the world and is a great power.

History
In 1225, The Ly Dynasty of Dai Viet collapsed and the Tran Dynasty was born.

After three Mongol invasions, Trần Hưng Đạo wanted Dai Viet not to be underestimated by greater nations like China and Mongolia. He wanted to expand the land of Dai Viet, making it great like its name.

In 1290, Dai Viet invaded Champa. Just three years after, in 1293, Champa was annexed to Dai Viet, as well as some parts of the unconquered southern land.

In 1295, Most of the unconquered land in the west (Laos) were annexed to Dai Viet.

Noticing the inanity of the Khmer Empire, Dai Viet invaded Khmer, much to their demise. They managed to successfully conquer all the land in three years. However, Trần Hưng Đạo died shortly after that. His son, Tran Quoc Hien, succeeded his father as the general.

In 30 years, the empire would become like the image here. This is Dai Viet's greatest territorial extent.

Nations declaring their independence
India was able to take back the invaded land after two years.

In the mid-14th century, the kingdom of Ayutthaya, was established after a successful rebellion. A peace treaty was signed to avoid future invasions between the two nations. The kingdom was later divided into Burma, Siam and Malaya.

French Dai Viet
In this timeline, the French never successfully colonized Dai Viet due to its size and power and the patriotism of the emperor. The United States, wanting the French to get out of Dai Viet, starting helping and having foreign relations with Dai Viet. With US intervention, Dai Viet would Westernize their government, turning it into a constitutional monarchy, much like Japan.

World War II
Dai Viet was invaded by Japan in 1940. Ther goal was to conquer all of the Far East, and block all of the US support for China during the Sino-Japanese War through the Haiphong Harbor. The new Prime Minister conducted a rebellion against the Japanese. During this time, a treason clan was set up by the Japanese as the "fascist collaborators" and created a puppet government called  "Empire of Dai Viet". The Japanese was able to took control until the bombings of Nagasaki and Hiroshima; when the rebellion successfully defeated the Japanese. Dai Viet would join the United Nations on October 24th, 1945.

Johnson South Reef Skirmish
On March 14, 1988, The People's Republic of China Navy sailed to the  Johnson South Reef in the Union Banks region of the Spratly Islands, which is a territory of Dai Viet. It was later known as a massacre in Dai Viet since the Chinese Navy killed all of the Daivietian Navy Soldiers on the island. After the conflict, the Daiviet Prime Minister had made a public speech, stating that "We consider that an act of war. The islands belong to Dai Viet. We demand a release of all the prisoners you have taken." Dai Viet removed all of its relations with China. No business of any kind is allowed. And after that was the Asian Cold War.
