Idris Alooma vs Peter I of Serbia

Idris Alooma introduced firearms, including muskets and cannons, to the Kanem-Bornu army. He hired Turkish and North African mercenaries to train his troops, creating a professional standing army that gave Bornu a military advantage.

Idris Alooma made a pilgrimage to Mecca, traveling through Egypt and Arabia. He established diplomatic ties with the Ottoman Empire and secured support for his military reforms, including the supply of firearms.

Idris Alooma led campaigns against the Sao people, who had long raided Bornu. He defeated them and incorporated their territory, securing the empire's southern borders and gaining control over trade routes.

Idris Alooma built fortified military camps (ribats) along Bornu's borders. These camps housed garrisons and served as bases for campaigns, improving defense against raids from the Tuareg and other groups.

Idris Alooma codified Islamic law and established a system of courts in Bornu. He appointed qadis (judges) and standardized legal procedures, strengthening the rule of law and centralizing authority.

Peter I Kara

King Peter I led Serbia during the First and Second Balkan Wars, which resulted in the expansion of Serbian territory and the expulsion of the Ottoman Empire from most of the Balkans. Serbia emerged as a regional power.

After the Austro-Hungarian and German invasion of Serbia, King Peter I led the Serbian army and government on a retreat through the mountains of Albania to the Adriatic coast. The retreat was a humanitarian disaster but preserved the army for future campaigns.

Following the end of World War I, King Peter I was proclaimed King of the newly formed Kingdom of Serbs, Croats, and Slovenes (later Yugoslavia). This united South Slavic peoples under a single monarchy.
