The band's final lineup consisted of vocalist Rui Martins, guitarists Steeves Hostin and Baptiste Vigier, bassist Valentin Hauser, drummer Boris le Gal, and keyboardist Victor Guillet.

Through their previous label, Sumerian Records, Betraying the Martyrs released four studio albums: Breathe in Life (2011), Phantom (2014), The Resilient (2017), and Rapture (2019).

On 18 November 2009, Betraying the Martyrs released their debut EP The Hurt the Divine the Light, a self-produced recording funded entirely by the band and mixed by Stephane Buriez.

The band met current vocalist, British native Aaron Matts (born 1990), during that tour, as he replaced Czaicki shortly thereafter.

The tour included performances in Germany, Russia, Ukraine, Poland, the Czech Republic, Switzerland, Austria, Luxembourg, Belgium, France, the Netherlands and the United Kingdom.

Later that year, during the northern fall, the band toured the United States with Born of Osiris, Veil of Maya, Carnifex and Structures.

The release of the video brought attention to the fact that Mark Mironov, BTM's drummer since 2012, sadly had been replaced.

Welcoming Boris Le Gal to take his place, the band released the following statement on their official website: "As some of you may have noticed, our adored drummer and friend Mark Mironov is no longer a present part of the BTM line-up; this comes as a result of on-going VISA issues with Mark being a citizen of Russia.

"[12] A third single was released on 30 November, "Lost for Words", featuring a symphonic background and a more prominent clean refrain from Victor Guillet.

[16] In an interview with Wall of Sound, Matts explained his departure was because "I've been wanting to sing about gross shit and just go all out crazy on it for so long.

"[17] On 14 October 2021, Betraying the Martyrs introduced their new singer Rui Martins on the release of their new single and its music video, "Black Hole".

[27] Betraying the Martyrs completed touring with Asking Alexandria, While She Sleeps and Motionless in White,[28] Chelsea Grin, Attila, and Within the Ruins.

They played during the Greenfield Festival in Switzerland alongside bands such as Rammstein, Queens of the Stone Age, The Prodigy and Parkway Drive.

AllMusic said the band is known to "temper the punishing brutality of deathcore with melodic flourishes pulled from symphonic and progressive metal, giving it a theatricality that feels distinctly European.
