Sigtrygg Gnupasson

Sigtrygg Gnupasson was semi-legendary a king of Denmark of the House of Olaf who ruled in the 10th century, according to Adam of Bremen.

He is remembered on the two Sigtrygg Runestones found near Schleswig, (DR2 and DR4), erected by his mother after his death, suggesting this area represented the power-base of the family.

The lost Gesta Wulinensis ecclesiae pontificum, of which the authenticity is highly disputed, states that Gnupa outlived his son Sigtrygg.

Adam himself mentions the existence of other kings at this time and expresses doubt that Denmark represented a single united realm.
