The Cần Vương movement was a large-scale Vietnamese insurgency between 1885 and 1889 against French colonial rule. Its objective was to expel the French and install the boy emperor Hàm Nghi as the leader of an independent Vietnam. The movement lacked a coherent national structure and consisted mainly of regional leaders who attacked French troops in their own provinces. The movement initially prospered as there were only a few French garrisons in Annam, but failed after the French recovered from the surprise of the insurgency and poured troops into Annam from bases in Tonkin and Cochinchina. The insurrection in Annam spread and flourished in 1886, reached its climax the following year and gradually faded out by 1889.

The Keelung campaign was a controversial military campaign undertaken by the French in northern Formosa (Taiwan) during the Sino-French War. After making a botched attack on Keelung in August 1884, the French landed an expeditionary corps of 2,000 men and captured the port in October 1884. Unable to advance beyond their bridgehead, they were invested inside Keelung by superior Chinese forces under the command of the imperial commissioner Liu Mingchuan. In November and December 1884 cholera and typhoid drained the strength of the French expeditionary corps, while reinforcements for the Chinese army flowed into Formosa via the Pescadores Islands, raising its strength to 35,000 men by the end of the war. Reinforced in January 1885 to a strength of 4,500 men, the French won two impressive tactical victories against the besieging Chinese in late January and early March 1885, but were not strong enough to exploit these victories. The Keelung campaign ended in April 1885 in a strategic and tactical stalemate. The campaign was criticised at the time by Admiral Amédée Courbet, the commander of the French Far East Squadron, as strategically irrelevant and a wasteful diversion of the French navy.

The Battle of Kirbekan was a battle in the Mahdist War. It was fought February 10, 1885, when the British Nile Column, about 1,000 strong, under General Earle, stormed the heights of Kirbekan, which were held by a strong Mahdist force, and totally routed them, with heavy loss.

The Nauruan Civil War was fought from 1878 to 1888, between forces loyal to incumbent King Aweida of Nauru and those seeking to depose him in favour of a rival claimant. The war was preceded by the introduction of firearms to Nauru. For the majority of the war, the loyalists and the rebels found themselves in a stalemate, with one side controlling the north and the other controlling the south. In 1888, The German Empire intervened and restored Aweida to the throne, although the island was annexed in the process. By the end of the war, about 500 people had died, around a third of the population.

The Nile Expedition, sometimes called the Gordon Relief Expedition (1884–85), was a British mission to relieve Major-General Charles George Gordon at Khartoum, Sudan. Gordon had been sent to the Sudan to help Egyptians evacuate from Sudan after Britain decided to abandon the country in the face of a rebellion led by self-proclaimed Mahdi, Mahommed Ahmed. A contingent of Canadians was recruited to help the British navigate their small boats up the Nile River. The Nile Expedition was the first overseas expedition by Canadians in a British imperial conflict, although the Nile Voyageurs were civilian employees and did not wear uniforms.

The Battle of Nui Bop was a French victory during the Sino-French War. The battle was fought to clear Chinese forces away from the French forward base at Chu, and was an essential preliminary to the Lạng Sơn Campaign in February 1885.

The Panjdeh incident was an armed engagement between Afghanistan and the Russian Empire in 1885 that led to a diplomatic crisis between the British Empire and the Russian Empire caused by the Russian expansion south-eastwards towards the Emirate of Afghanistan and the British Raj (India). After nearly completing the Russian conquest of Central Asia the Russians captured an Afghan border fort. Seeing a threat to India, Britain came close to threatening war but both sides backed down and the matter was settled by diplomacy. The effect was to stop further Russian expansion in Asia, except for the Pamir Mountains and to define the north-western border of Afghanistan.

The Peruvian civil war of 1884–1885 was an internal Peruvian conflict that resulted from Peru's defeat in the War of the Pacific. The casus belli was the Treaty of Ancon.

The Battle of Khartoum, Siege of Khartoum or Fall of Khartoum was the conquest of Egyptian-held Khartoum by the Mahdist forces led by Muhammad Ahmad. Egypt had held the city for some time, but the siege the Mahdists engineered and carried out from 13 March 1884 to 26 January 1885 was enough to wrest control away from the Egyptian administration. After a ten-month siege, when the Mahdists finally broke into the city, the entire garrison of Egyptian soldiers was killed along with 4,000 Sudanese civilians.

The Siege of Tuyen Quang was an important confrontation between the French and the Chinese armies in Tonkin during the Sino-French War. A French garrison of 630 men, including two companies of the French Foreign Legion, successfully defended the French post of Tuyen Quang against vastly outnumbering Chinese forces in a four-month siege from 24 November 1884 to 3 March 1885. 'Tuyen Quang 1885' remains one of the Legion's proudest battle honours.

The Sino-French War, also known as the Tonkin War and Tonquin War, was a limited conflict fought from August 1884 through April 1885. There was no declaration of war. Militarily it was a stalemate. The Chinese armies performed better than in other nineteenth-century wars and the war ended with French retreat on land. However, one consequence was that France supplanted China's control of Tonkin. The war strengthened the dominance of Empress Dowager Cixi over the Chinese government, but brought down the government of Prime Minister Jules Ferry in Paris. Both sides were satisfied with the Treaty of Tientsin. According to Lloyd Eastman, "neither nation reaped diplomatic gains."

The Battle of Slivnitsa was a decisive victory of the Bulgarian army over the Serbians on November 17–19, 1885 in the Serbo-Bulgarian War. It solidified the unification between the Kingdom of Bulgaria and Eastern Rumelia.

It was the final of three wars fought in the 19th century between the Burmese and the British. The war saw the loss of sovereignty of an independent Burma under the Konbaung dynasty, whose rule had already been reduced to the territory known as Upper Burma, the region of Lower Burma having been annexed by the British in 1853, as a result of the Second Anglo-Burmese War.

The Battle of Tofrek was fought on 22 March 1885 some 5 miles inland from the port of Suakin on the Red Sea coast of Sudan. A contingent of some 3000 troops from the British and Indian "Suakin Field Force" led by Major General Sir John Carstairs McNeill VC, GCVO, KCB, KCMG was attacked by a Mahdist force under the leadership of Osman Digna. The Mahdists were heavily defeated, losing some 1000 of their 2000 fighters as compared to the loss of 70 British and Indian soldiers plus over 100 casualties.

The Tonkin Affair, named after the French protectorate of Tonkin, of March 1885 was a major French political crisis that erupted in the closing weeks of the Sino-French War. It effectively destroyed the political career of the French prime minister, Jules Ferry, and abruptly ended the string of Republican governments inaugurated several years earlier by Léon Gambetta. The suspicion by the French public and political classes that French troops were being sent to their deaths far from home for little measurable gain, both in Tonkin and elsewhere, also discredited French colonial expansion for nearly a decade.

The Tonkin campaign was an armed conflict fought between June 1883 and April 1886 by the French against, variously, the Vietnamese, Liu Yongfu's Black Flag Army and the Chinese Guangxi and Yunnan armies to occupy Tonkin and entrench a French protectorate there. The campaign, complicated in August 1884 by the outbreak of the Sino-French War and in July 1885 by the Cần Vương nationalist uprising in Annam, which required the diversion of large numbers of French troops, was conducted by the Tonkin Expeditionary Corps, supported by the gunboats of the Tonkin Flotilla. The campaign officially ended in April 1886, when the expeditionary corps was reduced in size to a division of occupation, but Tonkin was not effectively pacified until 1896.

The Treaty of Tientsin, signed on June 9th, 1885, officially ended the Sino-French War. The unequal treaty restated in greater detail the main provisions of the Tientsin Accord, signed between France and China on May 11th, 1884. As Article 2 required China to recognize the French protectorate over Annam and Tonkin established by the Treaty of Hue in June 1884, which implicitly forced China to abandon its claims to suzerainty over Vietnam, the treaty formalized France's diplomatic victory in the Sino-French War.

The Battle of Zhenhai was a minor confrontation that took place on 1 March 1885 between Admiral Amédée Courbet's Far East Squadron and Chinese warships and shore batteries near the coastal city of Zhenhai, 12 miles (19 km) downstream from Ningbo, China during the Sino-French War. French and Chinese sources disagree sharply as to what happened; French sources treat the encounter as a minor incident, while Chinese sources consider it a striking defensive victory. The Battle of Zhenhai is still commemorated in China as an important Chinese victory in the Sino-French War.
