Ahmadou Tall vs Heonjong of Joseon

Ahmadou Tall succeeded his father Umar Tall as ruler of the Toucouleur Empire after Umar's death. He faced immediate challenges from rival brothers and regional rebellions, weakening the empire's unity.

Ahmadou Tall signed a treaty with France at Nango, recognizing French protectorate status over parts of the Toucouleur Empire. The treaty ceded territory and trade rights, marking the beginning of French domination over the empire.

French forces captured the Toucouleur capital of Segou, forcing Ahmadou Tall to flee eastward. The loss of the capital effectively ended Toucouleur sovereignty and marked the collapse of the empire.

Ahmadou Tall died in exile in Sokoto after years of fleeing French forces. His death ended the last remnants of Toucouleur resistance and the dynasty founded by his father.

King Heonjong ascended the throne at age 7, with the Andong Kim clan continuing to dominate the court. Queen Sunwon acted as regent. The clan's corruption and factionalism weakened the state and led to widespread discontent.

As Heonjong grew older, he attempted to reduce the Andong Kim clan's power by promoting officials from other factions. However, his efforts were largely unsuccessful due to the clan's entrenched influence. He died before achieving significant change.

King Heonjong died at age 22 without a son, ending the direct line of succession. His death led to a succession crisis, with the Andong Kim clan choosing a distant relative (Cheoljong) as the next king, perpetuating in-law rule.
