The region was especially attractive to German speakers and settlers, and when the town was established Hollenberg continued to draw to settlers of German, as well as Czech origin. Until World War I many residents of Hanover and the surrounding continued to speak their native languages, and to this day many German traditions remain an important aspect of town identity. German settlers often encountered Native people groups such as the Pawnee, Kansa, and the Kaw. Contact between the German settlers and natives were mainly non-violent and few conflicts were reported between the various groups. In fact, a substantial amount of trade took place between the settlers and the native groups.
