History

Gradually most residents moved over to the larger, more metropolitan city of Petersburg.

Kupreanof remained a separate municipality when the Petersburg Borough incorporated, unlike the neighboring city of Petersburg. However, Kupreanof now lies inside the Petersburg Borough, whereas before, it was a home-rule city inside the unorganized Petersburg Census Area.
