Hispania Balearica

Hispania Balearica was a Roman province encompassing the Balearic Islands off the east coast of modern Spain. Formerly a part of Hispania Tarraconensis, Balearica gained its autonomy due to its geographic separation and economic independence from the mainland. The province included three major islands: Balearis Major (Majorca), Balearis Minor (Minorca), and Ebusus (Ibiza), and the small island of Colubraria or Ophiusa (Formentera). The islands were grouped as the Gymnesiae—Majorca and Minorca, and the Pityusae—Ibiza and Formentera. From Wikipedia
