Sovereignty Claims

Where
Graham Island
Part of
The volcanic Graham Island briefly emerges in the Mediterranean

Multiple nations claimed sovereignty over the newly emerged island, leading to a four-way dispute that remained unresolved.

On 2 August 1831, Humphrey Fleming Senhouse, captain of HMS St Vincent, claimed the island for the British Crown and named it after Sir James Graham, the First Lord of the Admiralty, planting the Union Jack. An unnamed claimant named the island Julia, because it was born in July and probably also in reference to France's July Monarchy. During this time a four-way dispute over the island's sovereignty arose, which remained unresolved.
