Assassination of N'Jobu

"I found my daddy with panther claws in his chest! You ain't the son of a king, you're the son of a murderer!"

- Erik Killmonger to T'Challa

The Assassination of N'Jobu was an unplanned attack by Wakandan prince T'Chaka on his brother N'Jobu who betrayed his people.

Background
Over time, Wakandan Prince N'Jobu became convinced that Wakanda's isolationist policies were doing more harm than good and that people of African descent around the world were being oppressed. He then decided that the only course of action was to initiate a global revolution. To arm his cause, he revealed his country's existence to black-market arms dealer Ulysses Klaue and helped him infiltrate Wakanda in order to steal a cache of vibranium resulting in the deaths of several Wakandan citizens.

Assassination
Unbeknownst to both N'Jobu and Klaue, his brother T'Chaka had learned about his brother's treachery from his confidant Zuri, who previously disguised himself as an American citizen named James in order to gain the Prince's trust. T'Chaka made his way to the United States and confronted his brother. During the encounter, "James" revealed his true identity, so N'Jobu attempted to shoot him, only to be stopped by T'Chaka resulting in N'Jobu's death.

Aftermath
"No tears for me?" "Everybody dies. It's just life around here."

- N'Jobu and N'Jadaka

At that night N'Jobu's son Erik Stevens held his father's body and cried, before recovering his father's diary. Several years later, Stevens joined Navy SEALS and became Killmonger. He struck a deal with Klaue but later killed him and brought his body to Wakanda.

He then said to T'Challa that he wanted to be King of Wakanda, and revealed his true identity. Killmonger then challenged T'Challa to a duel, one which T'Challa accepted. In the duel, T'Challa was defeated and presumed dead, Zuri was killed and Killmonger became the King. As per tradition, Killmonger underwent the ritual of the Heart-Shaped Herb and traveled to the Ancestral Plane, where he conversed with his father one last time.
