Defense of the Great WallThe defense of the Great Wall () (January 1 – May 31, 1933) was a campaign between the armies of Republic of China and Empire of Japan, which took place before the Second Sino-Japanese War officially commenced in 1937 and after the Japanese invasion of Manchuria in 1931. It is known in Japanese as Operation Nekka and in many English sources as the First Battle of Hopei. During this campaign, Japan successfully captured the Inner Mongolian province of Rehe from the Chinese warlord Zhang Xueliang, and incorporated it into the newly created state of Manchukuo, whose southern frontier was thus extended to the Great Wall of China.
ManchuriaManchuria refers to a region in Northeast Asia encompassing the entirety of present-day Northeast China or, historically, those areas combined with parts of the Russian Far East (Russian Manchuria). Its definition may refer to varying geographical extents as following: the Chinese provinces of Heilongjiang, Jilin, and Liaoning but broadly also including the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng, collectively known as Northeast China.
Pacification of ManchukuoThe Pacification of Manchukuo was a Japanese counterinsurgency campaign to suppress any armed resistance to the newly established puppet state of Manchukuo from various anti-Japanese volunteer armies in occupied Manchuria and later the Communist Northeast Anti-Japanese United Army. The operations were carried out by the Imperial Japanese Kwantung Army and the collaborationist forces of the Manchukuo government from March 1932 until 1942, and resulted in a Japanese victory.
Inner MongoliaInner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia.

ManchukuoManchukuo, officially the State of Manchuria prior to 1934 and the Empire of Great Manchuria after 1934, was a puppet state of the Empire of Japan in Northeast China that existed from 1932 until 1945. It was founded ostensibly as a republic in 1932 from the lands seized by the Japanese during their invasion of Manchuria, and in 1934 it became a constitutional monarchy still under de facto Japanese control, with the final Emperor of China Puyi as its figurehead.
