The Anglo-Zulu War was fought in 1879 between the British Empire and the Zulu Kingdom.

The Second Anglo–Afghan War was fought between the United Kingdom and the Emirate of Afghanistan from 1878 to 1880, when the latter was ruled by Sher Ali Khan of the Barakzai dynasty, the son of former Emir Dost Mohammad Khan.

The war ended after the British emerged victorious against the Afghan rebels and the Afghans agreed to let the British attain all of their geopolitical objectives from the Treaty of Gandamak. Most of the British and Indian soldiers withdrew from Afghanistan. The Afghans were permitted to maintain internal sovereignty but they had to cede control of their nation's foreign relations to the British
