Hamengkubuwono IX vs Mai of Borno

Hamengkubuwono IX became the Sultan of Yogyakarta, a princely state in the Dutch East Indies. His reign began during the Japanese occupation, and he later played a key role in the Indonesian National Revolution.

Hamengkubuwono IX declared his support for the newly proclaimed Republic of Indonesia, offering Yogyakarta as the republic's capital. His decision provided a safe haven for the republican government during the war for independence.

Hamengkubuwono IX, along with other senior military figures, was involved in the transfer of executive authority from President Sukarno to General Suharto via the Supersemar document. This event marked the beginning of Suharto's New Order regime.

Hamengkubuwono IX was elected Vice President of Indonesia under President Suharto, serving until 1978. His role symbolized the integration of traditional Javanese monarchy into the modern Indonesian state.

Hamengkubuwono IX died in Jakarta and was given a state funeral. He was buried in the royal cemetery at Imogiri, Yogyakarta. His death marked the end of an era for the Yogyakarta Sultanate and Indonesian politics.

The Mai became the traditional ruler of the Bornu Empire, a Kanuri state in the Lake Chad region. His reign occurred during the empire's decline, facing pressure from the Fulani jihad and internal rebellions.

The Mai's army was defeated by Fulani jihadists at the Battle of Ngala, leading to the loss of western Bornu territories. This defeat weakened the empire's control over trade routes and reduced its political influence.

The Mai signed a commercial treaty with the British Empire, granting trading rights in Bornu. This agreement aimed to counter the Fulani threat by securing European support, but it also increased British influence in the region.
