The Battle over Tobacco happened when Persia started selling tobacco to Europe which made a leader, Jamal al-Din al-Afghani, outraged because he was against it and was for modernization of Persia. This caused riots to break out over tobacco and the ruler couldn't do anything about it. Resulting in Russia and Britain taking over Persia.
In 1899, the Boer War was a South African War between the British and the Boers. It was the first modern "total" war. Britain won this war in 1902.
