The name Kolt is a modern variant of the Old Norse name Koltr, which originated in Scandinavia during the Viking Age. It is derived from the Old Norse word "koltr," meaning "strip of land" or "clod of earth." The name likely referred to someone who lived or worked on a particular piece of land.

In ancient Norse mythology, there are no direct references to the name Kolt or its variants. However, the name may have been associated with the Norse god Freyr, who was revered as the god of fertility, prosperity, and the earth.

The earliest recorded use of the name Kolt dates back to the 11th century in Iceland. One of the earliest known individuals with this name was Kolt Þorvaldsson, an Icelandic chieftain who lived in the late 11th century.

Throughout history, there have been several notable individuals with the name Kolt or its variations:

1. Kolt Eriksson (c. 1220-1285), a Swedish nobleman and military commander during the Swedish-Novgorodian Wars.
2. Kolt Magnusson (c. 1340-1412), a Norwegian explorer and navigator who is believed to have explored parts of Greenland and the Arctic region.
3. Kolt Björnsson (c. 1480-1542), a Danish-Norwegian farmer and landowner who played a significant role in the Danish Reformation.
