Uli I of Mali

Mansa Uli, also known as Yérélinkon, was the second mansa of the Mali Empire. He was the son and successor of Sunjata.
Uli was one of the greatest rulers of Mali. The 20th-century historian Nehemia Levtzion suggested that Uli may have been the first mansa of Mali to extend his rule to Walata, Timbuktu, and Gao, though Timbuktu and Gao are usually regarded as later additions to the empire.

Name

Mansa Uli's real name is Kon, as his mother's name Jurunin was added as a prefix, people wrongly called him Yérélenkon. Because his body was clear, people called him Mansa Ulay, who was meant as the "red king".

Haji

Uli went on the hajj at some point between 1260 and 1277.
Uli was apparently succeeded by his brother Wati, who is not attested by oral tradition. Some oral traditions assert that Uli was Sunjata's only biological son, though Sunjata may have adopted others.

Sousou's migration

When Yérélenkon became the emperor, he claimed that his father didn't retaliate well at the Soso Empire. If he returned from his pilgrimage from Mecca, he would destroy the rest of them.
When the Soso's got information, they migrated to Jalon and confided in the Yalonke People. They remained there for many centuries until the Fulani's arrival in the seventeenth century, who changed their language from Mandingo to "proto-Yalonke". During the Fulani's arrival, the Yalonkes shared the lands giving to the Soso people to Fulani's who made them Immigrate to the coastal area.
Uli had a son, Qu, who would gain the throne during the early 14th century.
