ANCSA meaning in Regional ?

The Alaska Native Claims Settlement Act (ANCSA) was signed into law by President Richard Nixon on December 18, 1971, constituting at the time the largest land claims settlement in United States history. ANCSA was intended to resolve long-standing issues surrounding aboriginal land claims in Alaska, as well as to stimulate economic development throughout Alaska.

The settlement established Alaska Native claims to the land by transferring titles to twelve Alaska Native regional corporations and over 200 local village corporations. A thirteenth regional corporation was later created for Alaska Natives who no longer resided in Alaska. The act is codified as 43 U.S.C. 1601 et seq.
