Wakanda

"When stolen Wakandan Vibranium was used to make a terrible weapon, we in Wakanda were forced to question our legacy. Those men and women killed in Nigeria were part of a goodwill mission from a country too long in the shadows. We will not, however, let misfortune drive us back. We will fight to improve the world we wish to join."

- T'Chaka at the signing of the Sokovia Accords

Wakanda, officially the Kingdom of Wakanda, is a small, isolationist country located in the center of Africa. It is ruled by the heir of the title of Black Panther, and currently the only known source of the rare metal Vibranium.

Discovery of Vibranium
Howard Stark, founder and CEO of Stark Industries, sent his researchers to Africa. In one of its deepest regions, they managed to discover Vibranium, a rare metal that supposedly absorbed vibrations and kinetic energy naturally. Stark crafted a shield with the Vibranium to host a demonstration of this discovery at, a famous local nightclub in Los Angeles.

S.H.I.E.L.D. Surveillance
Wakanda was marked as a "hot-spot" for activities monitored by S.H.I.E.L.D. As such, it was displayed in the holographic maps used by the organization to oversee those activities, such as the ones present in the room where Nick Fury met with Tony Stark to discuss his formal integration into the Avengers Initiative.

Theft of Vibranium
Ulysses Klaue was in Wakanda once, where he stole large amounts of Vibranium and had the word "thief" branded on his neck.

Sokovia Accords
"You know if they find out he's here, they'll come for him." "Let them try."

- Steve Rogers and T'Challa After a terrorist attack in Lagos claimed the lives of twenty-six people, eleven of the victims being relief aid workers from Wakanda, King T'Chaka was one of several international politicians who called for the United Nations to create a system of accountability.

Sometime later, the United Nations passed the Sokovia Accords before arranging a formal ceremony at the Vienna International Centre in Austria. T'Chaka and his son T'Challa were among those in attendance.

During the ceremony, as T'Chaka gave the keynote address, a bomb detonated and decimated the building, killing T'Chaka and twelve other people.

Immediately following the bombing, T'Challa was crowned King and set out to avenge his father's death after security footage "revealed" that Bucky Barnes orchestrated the attack. He eventually learned, however, that former intelligence officer Helmut Zemo framed Bucky Barnes in an attempt to divide the Avengers.

Following Zemo's arrest, T'Chaka granted both Barnes and Steve Rogers asylum in Wakanda, promising to watch over Barnes as he chose to remaine in cryogenic stasis until his mind could be cleansed of the mental programming implemented by HYDRA.
