Kingdom of Earth (fictional)

The Kingdom of Earth, known as the Earth Kingdom at times, or simply called Earth, is a (fictional) nation that spans the entire world. The Kingdom of Earth rules every inch of the world with the exception of the Empire of the Philippines, State of Chula (California), the Collectivity of Malay Principalities, and the Holy City of Jerusalem. The Kingdom of Earth is ruled by a constitutional directorial monarchy, with the Earth King and the Council of Monarchs as the Head of State and the Supreme Chancellor as the Head of Government.

The Kingdom of Earth was established following the unification of the kingdoms of China, Korea, Japan, Dai Viet, Mongolia, and Tibet. All of the nations formed together to create the Kingdom of East Asia with the King of China being the monarch of East Asia. Over time, various nations joined the confederation. By the time of 1900, the entire world was united under one single monarch. However, in the early 2000s, the Chula State seceded, breaking the union. The Malay Principalities and Jerusalem also broke off, forming their own nations.

"Building the Roots"
The numerous kingdoms and republics in Southeast Asia have caused infinite chaos in the region. The biggest nation, the Kingdom of China, was already crippling apart and fragmenting. However, a prince of the Kingdom of China, known as "Delphin", secured Chinese stability and crowned himself the King of China, deposing his incompetent father.

King Delphin modernized the Chinese Army to be the biggest military in the world at the time. The fleet of Chinese Junks were known to be unsinkable and undestructable. Using their advanced army, China conquered the Kingdom of Dai Viet and incorporating the land into the Kingdom of China. The King of Dai Viet was allowed to keep his throne, now as an autonomous monarch under the authority of the King of China. With this, the Chinese army started their glorious conquest of the world.

After the Sino-Japanese War ended with the Chinese annexation of Japan, Korea, Manchuria, and Taiwan, China was renamed into the "Kingdom of East Asia". Following this transformation, the nations of Mongolia, Tibet, Xinjiang, Yunnan, Gansu, Laos, Kampuchea, Siam, and Myanmar all joined East Asia on the condition that their leader remained in power. Republics that joined (ex. Myanmar, Gansu), were rebranded as monarchies and their presidents renamed as kings.
