The regiment has its origins in fänikor (companies) raised in Hälsingland and Gästrikland in the 1550s and 1560s.

In 1615, these units—along with fänikor from the nearby provinces of Medelpad, Ångermanland and Västerbotten—were organised by Gustav II Adolf into Norrlands storregemente, of which eleven of the total 24 companies were recruited in Hälsingland and Gästrikland.

In 1973, the regiment gained the new designation I 14/Fo 49 as a consequence of a merge with the local defence area Fo 49.
