Bunad is a Norwegian umbrella term encompassing, in its broadest sense, a range of both traditional rural clothes (mostly dating to the 19th and 18th centuries) as well modern 20th century folk costumes. In its narrow sense the word bunad refers only to clothes designed in the early 20th century that are loosely based on traditional costumes. The word bunad in itself is a 20th century invention.

The bunad movement has its root in 19th century national romanticism, which included an interest for traditional folk costumes not only in Norway, but also in neighbouring countries such as Denmark and notably Germany. However, in Norway national romanticist ideas had a more lasting impact, as seen in the use of folk inspired costumes.

The designs are typically elaborate, with embroidery, scarves, shawls and hand-made silver or gold jewelry known as sølje. There are bunads both for men and women, although women's bunads are more diverse and popular. However, according to daily manager Turid Liss Agersborg at Husfliden Oslo, they now produce and sell more men’s bunads than women’s for the first time in history. The male customers are often characterized as urban and modern, and range between the ages of 20 and 40 years old.

Leif Ericson ( /ˈleɪf/ LAYF or /ˈliːf/ LEEF; Old Norse: Leifr Eiríksson; Icelandic: Leifur Eiríksson; Norwegian: Leiv Eiriksson c. 970 – c. 1020) was a Norseexplorer regarded as the first European to land in North America (excluding Greenland), nearly 500 years before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada.

It is believed that Leif was born around the 970s—the son of mother Thjodhild and father Erik the Red, an explorer and outlaw from Western Norway. Erik founded the first Norse colonies in Greenland, and was based at the family estate Brattahlíð in the so-called Eastern Settlement, where Leif had his upbringing. Leif had two known sons: Thorgils, born to noblewoman Thorgunna in the Hebrides; and Thorkell, who succeeded Leif as chieftain of the Greenland settlement.

Leif was the son of Erik the Red and his wife Thjodhild, and the grandson of Thorvald Asvaldsson. His year of birth is most often given as c. 970 or c. 980. Though Leif's birthplace is not accounted for in the sagas, it is likely he was born in Iceland, where his parents met—probably somewhere in Breiðafjörður, and possibly at the farm Haukadal where Thjodhild's family is said to have been based. Leif had two brothers, Thorstein and Thorvald, and a sister, Freydís.
