In 1932 the poem "Jólasveinarnir" was published as a part of the popular poetry book "Jólin Koma" (e. Christmass arrives) by Icelandic poet Jóhannes úr Kötlum. The poem reintroduced Icelandic society to Icelandic Yuletide folklore and established what is now considered the 'official' thirteen Yule Lads, their personalities and connection to other folkloric characters.
The Yule Lads are traditionally said to be the sons of the mountain-dwelling trolls Grýla and Leppalúði. Additionally, the Yule Lads are often depicted with the Yuletide Cat, a beast that, according to folklore, eats children that don't receive new clothes in time for Christmas.
In modern times the Yule Lads have been depicted as taking on a more benevolent role comparable to Santa Claus and other related figures and putting small gifts (or potatoes if the child has misbehaved) into shoes placed by children into their windows the last thirteen nights before Christmas Eve. They are occasionally depicted as wearing the costume traditionally worn by Santa Claus, but are otherwise generally shown wearing late medieval style Icelandic clothing.
