The city of Dnipropetrovsk was renamed Dnipro in May 2016 as part of the decommunization laws enacted a year earlier. Constitutional Court refused to consider renaming Dnipropetrovsk, Ukrayinska Pravda (12 October 2016)</ref> Dnipropetrovsk Oblast was not renamed because it is mentioned as such in the Constitution of Ukraine, and the oblast can only be renamed by a constitutional amendment. In April 2018 a group of over a hundred deputies formally initiated a proposal in the Ukrainian Parliament to change the name to Sicheslav Oblast; in February 2019, the Verkhovna Rada voted to officially amend the Constitution thus granting state sanction to the name change. Later that year the Constitutional Court officially approved the change. The oblast's administrative centre and largest city, Dnipro, had the unofficial name "Sicheslav" in 1918–21 during the Ukrainian War of Independence, commemorating the Zaporizhian Sich.
