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 monitorized 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
Wakanda also supported the Sokovia Accords, but lost their king in Helmut Zemo's revenge plot against the Avengers. Their prince, T'Challa sought to avenge him, but relented when he refused to let vengeance consume him. To atone for his attacks againt Captain America and Winter Soldier, he allowed the two refuge in Wakanda, even granting the latter access to his Cryostasis Chamber as a personal favor, as Bucky Barnes wished to remain under cryostatis until such a point when his HYDRA brainwashing could be undone.
