The band was formed in 2010 by Morgan Korsmoe and Ludwig Larsson. Morgan grew up playing bass in his father's band Larz Kristerz but had a heavy urge for the rockmusic of the 1970s and wanted to start a group playing hard rock/blues rock. Morgan and guitarist Ludwig recruited drummer Björn "Binge" Inge from the legendary Swedish hard-rock band November, Hammond organ playerMax Lorentz and the legendary rock vocalist Göran Edman, world known for his work with amongst others Yngwie Malmsteen. The group decided to write their own material in their native tongue of Swedish. October 2011 saw the release of Mårran's debut CD-single "Gärdesbrud" on Blind Boyscout Records in a limited edition of 500 copies. In March 2012 the debut album Mårran was released in Sweden on S-Rock Records produced and mixed by Max Lorentz. The songs on the album are:
1. Än sen
2. Folkvisa från Helvetet

On November 16, 2012 Mårran released their second album Mårran 2 in Sweden on S-Rock Records produced and mixed by Max Lorentz. The album got ever better reviews in the Swedish press.

On Record Store Day April 20, 2013 Mårran released a limited edition vinyl only single, each in its own unique cover made by the Swedish artist Anders Hultman. Hultman, who also constructed the "Mårran-train" depicted on Mårran 2, made the covers out of old record covers, mostly of the religious kind, from the 1960s. This was considered as an environmental statement for re-cycling. The songs were recorded during the making of Mårran 1.
