Emperor Kammu vs Sundiata Keita

Kammu launched a major military campaign to subdue the Emishi people in northern Honshu. The campaign was initially unsuccessful, with a defeat at the Battle of Koromo River, but later efforts under Sakanoue no Tamuramaro achieved victory.

Emperor Kammu moved the imperial capital from Nara to Heian-kyo (modern Kyoto). This relocation was intended to escape the influence of powerful Buddhist monasteries in Nara and marked the beginning of the Heian period.

Kammu commissioned the construction of several Buddhist temples in Heian-kyo, including To-ji and Sai-ji. These temples were intended to protect the new capital and promote Buddhism as a state religion.

Sundiata Keita led the Mandinka coalition against Soumaoro Kant

After the Battle of Kirina, Sundiata was proclaimed Mansa (emperor) of the Mali Empire at the Kouroukan Fouga assembly. He established a constitution and divided the empire into provinces, laying the administrative foundation of Mali.

Sundiata conquered the remnants of the Ghana Empire, incorporating its territory into Mali. This gave Mali control over the trans-Saharan gold trade routes, significantly increasing its wealth and power.

Sundiata established Niani as the capital of the Mali Empire. The city became a center of trade and governance, located near gold fields and on trade routes, facilitating the empire's economic growth.

Sundiata promoted the cultivation of cotton and the weaving of cloth, which became a major industry in Mali. This economic reform diversified the empire's economy and increased its self-sufficiency.
