Donghaegu

The term Donghaegu (: 东海寇), derived from a term meaning "eastern pirates", is an exonym originally used by historians from the late Cheonjean Empire to refer to maritime raiding peoples from Bangju and north Yeongju, especially Taniiluxans. Rather than a unified state or group of people, the Donghaegu comprised independent bands of raiders seeking wealth or glory. During the Donghaegu Age, which lasted from the 8th century CE to the end of the 11th century, the Donghaegu engaged in a vast campaign of raids radiating from Bangju to areas as distant as Jeongmi and Yaetteng. In some of the regions they raided—notably the northeast coast of Fusen—the Donghaegu formed permanent settlements and ruled as local princes. The cultural impacts of Donghaegu invasion and rule are felt in northeast Fusen and northwest Yeongju into the present day.
