[1] Every summer, Jerslev Marked, one of the largest market festivals in the region of its kind, is held.

In 1231, one of these herreds was recorded as Jarlsefheret, a name which implies that the town had been the seat of an earl (Danish: jarl).

[5] Jerslev Herred once covered a significant portion of central Vendsyssel and functioned as its own local government.

[6] By 1835, the administrative region was completely dissolved into the neighboring Herreds of Børglum and Dronninglund, though the town retained its name.

[7][8] Before the construction of a railroad through the neighboring city of Brønderslev, Jerslev was located at a heavily trafficked crossroads and in 1711 there were four substantial inns in the town.

[9] During the occupation of Denmark of World War II, approximately 150 German soldiers were quartered at the inn and the town hall.

The church underwent major renovation and expansion in 1927; the ceiling and pews were replaced, heating and electricity were installed, and a tower room and chapel were added to the existing structure.

[14][15] In 1877, the Danish-American minister, John G. Matteson returned to Denmark to organise a Seventh Day Adventist congregation in Vendsyssel.
