In 1880, Chief Kaawaa’ee, a Tlingit of the Aak’w Kwáan, led Joe Juneau and Dick Harris to gold. Prior to the gold find, the non-Native population in Alaska was less than 400. After the discovery, thousands of miners and settlers arrived. This put pressure on Tlingit land. The Organic Act of 1884 established a land district (a type of administrative land division) and branches of government in Alaska. The law gave title to land held by non-Native people in the new territory, but did not allow Alaska Natives to acquire title to their land. The first duty of the new land office was to give legal title to mining claims. A number of Tlingit people attempted to file mining claims, but were denied because they were not United States citizens. Although the Tlingit still owned southeast Alaska under aboriginal title (a common law doctrine that the land rights on indigenous people persist even after settler colonialism), they did not benefit from wealth generated by the mineral resources
