Peter II von Turn
Peter II von Turn (c. 1260–1308), son of Aymon II, was the first of his house to style himself baron of Niedergesteln at the Gestelnburg in the Valais. In 1291 he served the counts of Savoy as Landvogt of the Waadt.
He led the Valais nobility in revolt against Bishop Boniface de Challant of Sion, but after defeat at the Sustmatten in 1296 he made peace with the bishop in 1299. He ruled until his death in 1308 and was followed by his son Johann.
