Yukon was split from the Northwest Territories in 1898 and was originally named the Yukon Territory. The federal government's Yukon Act, which received royal assent on March 27, 2002, established Yukon as the territory's official name, though Yukon Territory is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of YT. Though officially bilingual (English and French), the Yukon Government also recognizes First Nations languages.
The History of Yukon begins with disputed evidence of the oldest remains of human inhabitation in North America. A large number of apparently human-modified animal bones were discovered in the Old Crow area in the northern Yukon that have been dated to 25,000–40,000 years ago by carbon dating. The central and northern Yukon were not glaciated, as they were part of Beringia.
