The Prespa agreement of June 2018 saw the country change its name to the ''Republic of North Macedonia'' eight months later. A non-binding national referendum on the matter passed with 90% approval but did not reach the required 50% turnout amidst a boycott, leaving the final decision with parliament to ratify the result. Parliament approved of the name change on 19 October, reaching the required two-thirds majority needed to enact constitutional changes. The vote to amend the constitution and change the name of the country passed on 11 January 2019 in favour of the amendment. The amendment entered into force on 12 February, following the ratification of the Prespa agreement and the Protocol on the Accession of North Macedonia to NATO by the Greek Parliament. Despite the renaming, the country is unofficially referred to as 'Macedonia' by most of its citizens and most of the local media outlets.
