It is known in Japanese as Operation Nekka and in many English sources as the First Battle of Hopei.
The Battle of Rehe was the second part of Operation Nekka, a campaign by which the Empire of Japan successfully captured the Inner Mongolian province of Rehe from the Chinese warlord Zhang Xueliang and annexed it to the new state of Manchukuo.

The Second Zhili–Fengtian War of 1924 was a conflict between the Japanese-backed Fengtian clique based in Manchuria, and the more liberal Zhili clique controlling Beijing and backed by Anglo-American business interests. The war is considered the most significant in China's Warlord era, with the Beijing coup by Christian warlord Feng Yuxiang leading to the overall defeat of the Zhili clique. During the war the two cliques fought one large battle near Tianjin in October 1924, as well as a number of smaller skirmishes and sieges. Afterwards, both Feng and Zhang Zuolin, the latter being ruler of the Fengtian clique, appointed Duan Qirui as a figurehead prime minister. In south and central China, more liberal Chinese were dismayed by the Fengtian's advance and by the resulting power vacuum. A wave of protests followed. The war also distracted the northern warlords from the Soviet-backed Nationalists based in the southern province of Guangdong, allowing unhampered preparation for the Northern Expedition (1926–1928), which united China under the leadership of Chiang Kai-shek.
Pang Bingxun was a high-ranking nationalist military commander who fought against the Imperial Japanese Army and Chinese Communist Army. He stopped the IJA 5th Division led by General Seishirō Itagaki, one of the principal architects of the 1931 Manchurian incident, from capturing Linyi and converging with General Rensuke Isogai's IJA 10th Division at Tai'erzhuang District, foiling their plan to assault Xuzhou.
The 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.
Tang Yulin was a Chinese general who served in the Northeastern Army. An important member of the Fengtian clique that governed Manchuria during the Warlord Era, he served as warlord of Rehe Province. His military incompetence was a major factor Japan's successful invasion of that province in 1934.
The Jilin Self-Defence Army was an anti-Japanese volunteer army formed in 1931 to defend local Chinese residents against the Japanese invasion of northeast China. General Ding Chao, Li Du, Feng Zhanhai, Xing Zhanqing, and Zhao Yi organised the Jilin Self-Defence Army in order to prevent the fall and occupation of Harbin city, Jilin province. This brought all their forces under a unified command. Calling for civilians to form volunteer units and join in the defense of the city, the army reached a strength of 30,000 men in six brigades of Zhang Xueliangs Northeastern army.

The Inner Mongolian campaign in the period from 1933 to 1936 were part of the ongoing invasion of northern China by the Empire of Japan prior to the official start of hostilities in the Second Sino-Japanese War. In 1931, the invasion of Manchuria secured the creation of the puppet state of Manchukuo and in 1933, Operation Nekka detached the province of Jehol/Rehe from the Republic of China. Blocked from further advance south by the Tanggu Truce, the Imperial Japanese Army turned its attention west, towards the Inner Mongolian provinces of Chahar and Suiyuan, with the goal of establishing a northern China buffer state. In order to avoid overt violation of the Truce, the Japanese government used proxy armies in these campaigns while Chinese resistance was at first only provided by Anti-Japanese resistance movement forces in Chahar. The former included in the Inner Mongolian Army, the Manchukuo Imperial Army, and the Grand Han Righteous Army. Chinese government forces were overtly hostile to the anti-Japanese resistance and resisted Japanese aggression only in Suiyuan in 1936.
