evidence: The town of Olivenza was under Portuguese sovereignty almost continuously between 1297 (Treaty of Alcañices) and 1801, when it was occupied by Spain during the War of the Oranges and ceded that year under the Treaty of Badajoz. Spain has since administered the territory (now split into two municipalities, Olivenza and also Táliga), whilst Portugal invokes the self-revocation of the Treaty of Badajoz, plus the Treaty of Vienna of 1815, to claim the return of the territory. In spite of the territorial dispute between Portugal and Spain, the issue has not been a sensitive matter in the relations between these two countries.
