The roots of this band date back to the year 1997, when Emilio and Matias formed a 4 member band named Century. This project became of lesser importance when both joined Feanor, and was finally postponed in 2001 when the two musicians became full members of this band. The year 2004 saw the re-awakening and continuation of the project and furthermore a name change from Century to Skiltron.

The band's name is derived from the term schiltron (also sheltron, shiltron or schiltrom), which refers to a formation of soldiers carrying pikes and polearms held in front of them to fight off approaching cavalry. In the First War of Scottish Independence, the Battle Bannockburn was won by the Scots using an offensive variation of this military formation. This modified tactic was a response to the crushing defeat that resulted from the schiltron's traditional defensive use in the Battle of Falkirk sixteen years earlier.

Bagpipe player Pablo Allen also took over woodwind duties when Diego Spinelli left Skiltron.

Four members of the band departed in 2011 and started a project in a similar style called Triddana.

Skiltron played their first ever European show on August 25th 2012 when Emilio Souto and Matias Pena performed a short set with Martin Walkyier and members of Achren at the Wallace Day celebration in Elderslie, Scotland.

Skiltron have made their first two albums available for free download through Don't Pay Music.

Keeping with the band's affiliation for Scottish history, they contributed the song "The Ballad of William Kidd" to the Running Wild tribute: "Reunation - A Tribute to Running Wild".

In 2014 the band played in Europe once again, featuring the festivals HORNERFEST and DONG OPEN AIR, playing together with bands like ANNIHILATOR, GRAVE DIGGER and ARCH ENEMY.

Throughout the last 10 years, Skiltron have constantly earned recognition within the Folk and Metal scene, projecting themselves as one of the references of the style.
