Snorri Sturluson relates that Tiundaland was the richest and most fertile region of Sweden. It was the seat of the Swedish kings at Uppsala and later the Swedish Archbishopric. All the Swedish lawspeakers were subordinate to the lawspeaker of Tiundaland.

The name of Attunda was revived as Attunda district court (Attunda tingsrätt) in April 2007, through the fusion of Sollentuna and Södra Roslags district courts. The seat of Attunda district court is situated in Sollentuna Municipality.
