where did the vibranium for captain americas shield come from
Captain America's shield While the origin and fate of the original shield were not described in the original comics from the 1940s, the shield's fate was revealed decades later in 2001 through a retconned story. According to the tale, King T'Chaka of the African nation Wakanda met Captain America in early 1941 and gave him a second sample of vibranium, an alien metal with unique vibration absorption properties and found only in Wakanda and the Savage Land.[4] The new Vibranium sample was used to make Captain America's circular shield and his triangular one was retired.
Captain America: Civil War Impersonating a psychiatrist sent to interview Barnes, Zemo recites the words to make Barnes obey him. He questions Barnes, then sends him on a rampage to cover his own escape. Rogers stops Barnes and sneaks him away. When Barnes regains his senses, he explains that Zemo is the real Vienna bomber and wanted the location of the Siberian Hydra base, where other brainwashed "Winter Soldiers" are kept in cryogenic stasis. Unwilling to wait for authorization to apprehend Zemo, Rogers and Wilson go rogue, and recruit Maximoff, Clint Barton, and Scott Lang to their cause. With Ross's permission, Stark assembles a team composed of Romanoff, T'Challa, James Rhodes, Vision, and Peter Parker to capture the renegades. Stark's team intercepts Rogers' group at Leipzig/Halle Airport, where they fight until Romanoff allows Rogers and Barnes to escape. The rest of Rogers' team is captured and detained at the Raft prison, while Rhodes is partially paralyzed after being inadvertently shot down by Vision, and Romanoff goes into exile.
