While several countries made [[territorial claims in Antarctica|claims to parts of Antarctica]] in the first half of the 20th century, the remainder, including most of [[Marie Byrd Land]] (the portion east from [[150th meridian west|150°W]] to [[90th meridian west|90°W]]), has not been claimed by any sovereign state. Signatories to the [[Antarctic Treaty System|Antarctic Treaty]] of 1959 agreed not to make such claims, except the [[Soviet Union]] and the [[United States]], who reserved the right to make a claim in the future.<ref>{{cite journal |last1=Dodds |first1=Klaus |title=Governing Antarctica: Contemporary Challenges and the Enduring Legacy of the 1959 Antarctic Treaty |journal=Global Policy |date=2010 |volume=1 |issue=1 |pages= |url=https://onlinelibrary.wiley.com/doi/full/10.1111/j.1758-5899.2009.00006.x |access-date=30 May 2025 |at=Historical Context |location=Wiley Online Library}}</ref>

An undefined area from [[20th meridian west|20°W]] to [[45th meridian east|45°E]] was historically considered potentially unclaimed; the Norwegian claim in [[Queen Maud Land]] was interpreted as covering the coastal regions, but not continuing all the way to the South Pole. In 2015, the claim was extended to reach as far as 90°S.<ref>{{cite news |last=Rapp|first=Ole Magnus |title = Norge utvider Dronning Maud Land helt frem til Sydpolen |journal=Aftenposten |url = https://www.aftenposten.no/norge/i/dw1q/norge-utvider-dronning-maud-land-helt-frem-til-sydpolen |access-date=22 September 2015 |date=21 September 2015 |location=Oslo, Norway |language=no |quote = …formålet med anneksjonen var å legge under seg det landet som til nå ligger herreløst og som ingen andre enn nordmenn har kartlagt og gransket.
