The answer is 1999 because Nunavut was established as a Canadian territory on April 1, 1999. Prior to this, it was part of the Northwest Territories. The creation of Nunavut was a result of the Nunavut Land Claims Agreement, which aimed to provide self-government and land rights to the Inuit people in the region. Therefore, 1999 marks an important milestone in the history of Nunavut as it became a separate territory with its own government and distinct cultural identity.
