<h1 class="pgc-h-arrow-right" data-track="4" > north Korea's geographic location</h1>
North Korea is a peninsula in Northeast Asia, surrounded by the sea on three sides, connected to the Russian Federation to the northeast, and bordered by the People's Republic of China across the Yalu River and the Tumen River in the northwest. North Korea has an average elevation of about 440 meters above sea level, and its mountainous terrain accounts for about 80% of the country.
North Korea's geographical location is extremely important to China, and if it is occupied by hostile forces, China's northeast will be completely exposed to hostile forces.
<h1 class="pgc-h-arrow-right" data-track="1" > the historical origins of China and North Korea</h1>
North Korea and China have deep historical ties.
Korea first appeared in Sima Qian's "Records of History", Shang's uncle Jizi fled to northern Korea after the fall of the Shang, the Zhou Dynasty recognized his country, and King Wu of Zhou made Jizi the Marquis of Joseon, known in history as "Jizi Joseon".
Hundreds of years after the "Mizi Joseon", Wei Man, who fled from the Han Dynasty, ran to Korea to drive out the then monarch Ji Zhun and established the "Wei Man Joseon". The "Wei Manchu Joseon" was destroyed by the Han Wu Emperor Liu Che, and the Korean Peninsula became several counties of the Han Dynasty. After the fall of the Han Dynasty, Korea was divided into three states, Goguryeo, Baekje, and Silla.
Silla and the Tang Dynasty joined forces to destroy Baekje and Goguryeo, taking advantage of the situation to unify the Korean Peninsula. Later, after a series of divisions and unification processes, the Goryeo Dynasty was established. In 1231, the Mongols destroyed Goryeo and established provinces, and within a few years the Goryeo rebellion was restored.
After the fall of the Yuan Dynasty in 1368, Li Chenggui launched a coup d'état and established himself as king, changing the name of the country to Joseon, and establishing friendly relations with the Ming Dynasty.
In 1591, after the Japanese Toyotomi Hideyoshi unified Japan, he sent 200,000 troops to invade Korea, in a vain attempt to use Korea as a springboard to invade the Ming Dynasty at that time, and once occupied Pyongyang. The Chinese Ming Emperor Wanli sent 100,000 troops to aid Korea, and after 8 years finally defeated the Japanese army, preserved the Korean mountains and rivers, the friendship between China and North Korea reached its peak in history, and the Korean king was grateful to the Ming Dynasty and vowed to become a Ming Dynasty vassal forever. After the Qing Dynasty replaced the Ming Dynasty, Korea became a vassal state of the Qing Dynasty.
In 1895, the Sino-Japanese Treaty of Maguan ended Sino-Korean clan relations, China recognized the independence of Korea, and Korea became a "protectorate" of Japan. After the victory in the Russo-Japanese War, Japan annexed Korea in 1910, and Korea officially became a springboard and military base for Japan to attack China. From then on, Japan began to use Korea as a springboard to begin its aggression against China.
<h1 class="pgc-h-arrow-right" data-track="16" > the division of North Korea</h1>
From February 4 to February 11, 1945, at the Yalta Palace on the Crimean Peninsula in the northern Black Sea of the Soviet Union, the leaders of the United States, the Soviet Union, and Britain, Roosevelt, Stalin, and Churchill, held a crucial summit on the formulation of a new post-war world order and the distribution of the interests of the great powers.
The meeting affected many countries that were unable to have leaders present, including the Korean Peninsula.
After Japan's surrender in 1945, the United States and the Soviet Union divided the Korean Peninsula into two countries, bounded by the 38° north latitude line. With the support of the United States, Syngman Rhee established the Republic of Korea in the southern part of the Korean Peninsula in August 1948. With the support of the Soviet Union, Kim Il Sung established the Democratic People's Republic of Korea in the northern part of the Korean Peninsula in September 1948. Both sides declared the sole legitimate government on the Korean Peninsula.
In this way, the Korean Peninsula, which ended colonial rule, was divided into two countries with completely different ideologies, laying the foundation for the subsequent Korean Civil War.
<h1 class="pgc-h-arrow-right" data-track="23" > The Korean War</h1>
Two countries split into the same ancestor, and neither side obeys the other, then military friction is a common thing. From January 1949 to June 1950, there were more than 2,000 disputes between the two Koreas near the "38th Line." Then the occurrence of a large-scale military conflict to seek the reunification of the peninsula is also inevitable. So who moved the hand first?
After the collapse of the Soviet Union, with the publication of the archives of the former Soviet Union, historians widely acknowledged that at 4 a.m. on June 25, 1950, with Stalin's consent, North Korean Prime Minister Kim Il Sung ordered the army to cross the 38th Line and launch a surprise attack on South Korea.
The Korean War was originally a national civil war between the north and the south on the Korean Peninsula. Because of the intervention of the United Nations military led by the United States, which forced China to enter the war, the war turned into an international local war, resulting in the death of more than 3 million civilians and the enlistment of about 3 million refugees.
Chinese People's Volunteer Army, a name that makes Americans shudder and reluctant to mention; the name that makes the Western world tremble is about to enter the stage of history.
