Wartime sexual violence
Primarily the Imperial troops, most notably the "Clerfayt" Regiment, badly misbehaved by robbing, raping and killing.: 129–131  Both Imperial and Patriot sources report an astonishing lack of discipline amongst the Imperial soldiers, and that their crimes committed against civilians at the early stages of combat was a crucial factor in motivating the civilian population of Ghent to side with the rebels.: 133–134

Ottoman-Saudi War: The historian Abd al-Rahman al-Jabarti recorded in his history, The Marvelous Compositions of Biographies and Events (‘Aja’ib al-athar fi’l-tarajim wa’l-akhbar), that Ottoman forces in the Ottoman-Saudi War took Wahhabi Saudi women and girls as slaves, despite them being Muslim and enslavement of Muslims being illegal. The jihadist Islamist Saudi Nasir al-Fahd mentioned the Ottoman enslavement of Saudi women and girls in his book attacking the Ottomans, The Ottoman State and the Position of the Call of Sheikh Muhammad ibn Abd al-Wahhab on it, published in 1993.

Circassian genocide: Cossacks raped Muslim Circassian women.
Russians raped Circassian girls during the 1877 Russo-Turkish war from the Circassian refugees who were settled in the Ottoman Balkans.

Indian Rebellion of 1857: During the Indian Rebellion of 1857, known as "India's First War of Independence" to the Indians and as the "Sepoy Mutiny" to the British, Indian sepoys rebelled en masse against the East India Company's rule over India. Incidents of rape committed by Indian sepoys against British women and children were reported in the English press, particularly after British civilians fell into Indian hands after sieges such as at Cawnpore. However, after the rebellion was suppressed, detailed analyses by the British government concluded that although Indian sepoys had engaged in massacres of British civilians after they captured them, there had never been one single instance of war rape committed by the sepoys. One such account published by The Times, regarding an incident where 48 British girls as young as fourteen and ten had been raped by the Indian sepoys in Delhi, was criticised as an obvious fabrication by Karl Marx, who pointed out that the story was written by a clergyman in Bangalore, while the rebellion was mostly confined to the Punjab region.
As British troops suppressed the rebellion, angered by reports of massacres and rapes of British civilians, reprisals were often carried out against Indian civilians, particularly at Cawnpore. Indian women were often a target of rape by the enraged soldiers.

Boxer Rebellion: During the Boxer Rebellion, the Yihetuan committed several massacres of foreign civilians (motivated by their anti-Christian and anti-Western sentiment) but were said to avoid raping women.
The majority population of the hundreds of thousands of people living in the inner "Tartar" city of Beijing during the Qing were Manchus and Mongol bannermen from the Eight Banners after they were moved there in 1644. During the Boxer Rebellion in 1900, western and Japanese soldiers mass raped Manchu women and Mongol banner women.
Indeed, it appeared common practise for the invading soldiers to capture women, regardless of class or creed, to rape them. This was done by forcing them to work as sex slaves in rape-manors they had established in the Beijing hutongs (alleys formed by siheyuan residences). This excerpt from the "Miscellaneous Notes about the Boxers", written by Japanese journalist Sawara Tokusuke, describes one such rape-manor:

The Allied forces would frequently capture women, no matter virtuous, wretched, old or young, and would, as much as they could, displace them to Biaobei alleys and to live in row houses there as prostitutes for the soldiery. The West end of this alley the path would have been blocked off, in order to prevent escape, the East end was the only way in or out. This way was guarded. Any person from the Allied forces could enter for pleasure and rape to his heart's desire.
Sawara also reports on the seven daughters of the Manchu bannerman Yulu 裕禄 of the Hitara clan, the Viceroy of the province of Zhili (present day Hebei). Yulu was on good terms with the invaders. He was a man who always sought to create good impressions, and due to this, the British Consul at Tianjin offered him asylum on board of one of Her Majesty's ships for his loyalty to the British (Fleming 84). Later in the war Yulu perished in the battle for Yangcun. When Beijing fell, the Allies abducted all seven of his daughters and then sent them to the Heavenly Palace in Beijing where they were violated repeatedly. Then they were held captive as sex slaves for the soldiers in one of the rape-manors mentioned above (Sawara 268).
Another story relays the fate that befell the women of Chongqi's household. Chongqi 崇绮 was a nobleman from the Mongolian Alute clan and scholar of high standing in the Imperial Manchu court. He was also the father-in-law of the previous Emperor. His wife and one of his daughters, much like Yulu's daughters, were captured by the invading soldiers. They were taken to the Heavenly Temple, held captive and were then brutally raped by dozens of Eight Nations Alliance soldiers during the entire course of the Beijing occupation. Only after the Eight Nations Alliance's retreat did the mother and daughter return home, only to hang themselves from the rafters. Upon this discovery, Chongqi, out of despair, soon followed suit (Sawara 266). He hanged himself on 26 August 1900. His son, Baochu, and many other family members committed suicide shortly after (Fang 75).
Many Manchu bannermen in Beijing supported the Boxers in the Boxer Rebellion and shared their anti-foreign sentiment. The Manchu bannermen were devastated by the fighting during the First Sino-Japanese War and the Boxer Rebellion, sustaining massive casualties during the wars and subsequently being driven into extreme suffering and hardship. The forces of the Eight-Nation Alliance, upon their capture of Beijing, went on violent rampages against Manchu civilians, looting, raping, and murdering numerous civilians they came across. The number of women who committed suicide numbered in the thousands. A western Journalist, George Lynch, said "there are things that I must not write, and that may not be printed in Great Britain, which would seem to show that this Western civilization of ours is merely a veneer over savagery." All of the eight nations in the alliance engaged in looting and war rape. Luella Miner wrote that the behavior of the Russians and French was particularly appalling. Qing women and girls killed themselves in order to avoid being raped. The French commander dismissed the rapes, attributing them to the "gallantry of the French soldiers".
Manchu property including horses and cattle were looted while their villages were burnt by the Russian Cossacks as Manchus were driven out as refugees and slaughtered by Russian cossacks according to S. M. Shirokogoroff when he was in Heilongjiang along the Amur river garrison of Heihe (Aihun). Manchu banner garrisons were annihilated on 5 roads by Russians as they suffered most of the casualties. Manchu Shoufu killed himself during the battle of Peking and the Manchu Lao She's father was killed by western soldiers in the battle as the Manchu banner armies of the Center Division of the Guards Army, Tiger Spirit Division and Peking Field force in the Metropolitan banners were slaughtered by the western soldiers. Baron von Ketteler, the German diplomat was murdered by Captain Enhai, a Manchu from the Tiger Spirit Division of Aisin Gioro Zaiyi, Prince Duan and the Inner city Legation Quarters and Catholic cathedral were both attacked by Manchu bannermen. Manchu bannermen were slaughtered by the Eight Nation Alliance all over Manchuria and Beijing because most of the Manchu bannermen supported the Boxers in the Boxer rebellion. The clan system of the Manchus in Aigun was obliterated by the despoliation of the area at the hands of the Russian invaders.

Russo-Japanese war: It was reported in 1905 that many Russian women were raped by Japanese troops causing widespread venereal disease in many Japanese troops after the Russo-Japanese War. Hal Gold estimated there were 20,000 recorded incidents of rape against Russian women.

German South-West Africa: In German South-West Africa during the Herero rebellion against German rule (and the subsequent Herero and Namaqua Genocide), German soldiers regularly engaged in gang rapes before killing the women or leaving them in the desert to die; a number of Herero women were also violently forced into involuntary prostitution.: 31

Xinhai revolution: In October 1911, during the Xinhai revolution, revolutionaries stormed the Manchu quarter of Xi'an. Most of the city's 20,000 Manchus were killed. The Hui Muslim community was divided in its support for the revolution. The Hui Muslims of Shaanxi supported the revolutionaries, while the Hui Muslims of Gansu supported the Qing.
