Petar I of Serbia vs Tewodros II

Petar I became King of Serbia in June 1903 after the assassination of Alexander I and the end of the Obrenovic dynasty. His accession restored the Karadjordjevic dynasty to the throne.

Petar I led Serbia during the First and Second Balkan Wars (1912-1913), which resulted in significant territorial expansion. Serbia gained Kosovo, Macedonia, and parts of Albania, doubling its territory.

Petar I led Serbia through World War I after the Austro-Hungarian invasion in 1914. Despite initial victories, Serbia was overrun in 1915, and the king led the army and government in exile on Corfu.

Petar I was proclaimed King of the newly formed Kingdom of Serbs, Croats, and Slovenes in December 1918. This united South Slavic peoples into a single state, later known as Yugoslavia.

Kassa Hailu (later Tewodros II) defeated the forces of Dejazmach Wube Haile Maryam at the Battle of Ayshal. This victory consolidated his control over northern Ethiopia and paved the way for his coronation as Emperor.

Kassa Hailu was crowned Emperor Tewodros II at the church of Derasge Maryam. He began a campaign to unify Ethiopia's fragmented provinces, centralize power, and modernize the military and administration.

Emperor Tewodros II imprisoned British missionaries and diplomats, including Consul Charles Duncan Cameron, after failing to receive a response from Queen Victoria to his letter requesting military assistance. This act led to the British Expedition to Abyssinia.

British forces under General Robert Napier stormed the fortress of Magdala, defeating Tewodros II's army. Rather than surrender, Tewodros committed suicide with a pistol given to him by Queen Victoria. His death ended the British Expedition to Abyssinia.
