HYDRA Uprising

The HYDRA conflict, also known as the HYDRA infiltration, was a major conflict that went back to as early as the 1940s. After World War II, the security agency S.H.I.E.L.D. was founded, but was soon infiltrated by HYDRA, the Nazi science group originally formed by the Red Skull prior to his disappearance. For the next several decades, HYDRA grew within S.H.I.E.L.D.'s ranks, manipulating the agency for to suit their plans. In 2014, the infiltration was exposed during Project Insight, and HYDRA, in an effort to save itself, started purging all S.H.I.E.L.D. facilities of non-HYDRA aligned individuals.
