Among Deia's founding principles were the highlighting of timely and accurate information as well as focusing on news about individual and collective human rights, promoting solidarity of Basque society, defending Basque tradition, culture, language, politics, social life and family, alongside the promotion of the coexistence of its inhabitants within democratic institutions. Although at an early stage Deia assumed the daily role of unifying of all current opinions that opposed the dictatorship, their lack of definition made the daily newspaper seek a closer identification with the moderate Basque nationalists, represented publicly by the Partido Nacionalista Vasco.
