Early years and The New Reign (2003–2007)

In its early years, the band was part of the Northland Chicago metalcore scene along with other (now successfully signed) bands such as Veil of Maya, Monsters, Oceano, and For All I Am. The band members attended the same high school, Fremd High School.

While known as Diminished in 2003, they released a five-song demo EP titled Your Heart Engraved These Messages. This was the only release from the teenage band to feature two lead vocalists.

From that demo came their next name, Your Heart Engraved. Under that name, the band released a twelve-song demo known as Youm Wara Youm. During that time, the band also released a satirical rap song titled "Stressed". The song was originally featured on the band's Myspace account.

The band changed names once again in 2006, this time to Rosecrance. They released a self-titled seven-track demo EP, containing re-recordings of songs off their second demo and two extra satirical rap songs, named "HopeYouDie" and "Paddy Wack". The latter was based on the nursery rhyme of the same name.

In 2007, the group settled on Born of Osiris as a suitable band name. The first Born of Osiris song released was "Narnia", which would later be retitled "The Takeover" on The New Reign. The New Reign marked the end of their satirical rap songs and old post-hardcore/metalcore sound, and it marked the beginning of their critically acclaimed technical deathcore sound as well as the start of their stay with Sumerian Records.

A Higher Place, The Discovery and Richardson's departure (2008–2012)

In July 2009, the band released their debut album, A Higher Place, which peaked at number 73 on the Billboard 200.^[3] They co-headlined a tour named The Night of the Living Shred with All Shall Perish, After the Burial, Caliban and Suffokate;^[4] Born of Osiris also supported Hatebreed on the Decimation of the Nation Tour 2, alongside Cannibal Corpse, Unearth and Hate Eternal.^[5]

This began a two-year period of member stability which resulted in the writing and release of their second full-length album, The Discovery. Released on March 22, 2011, the album debuted at 87 on the Billboard 200.

In September 2011, members Cameron Losch, Joe Buras, and Lee McKinney recorded and mixed the self-titled first release by Virginia band Mind's I.

David Darocha has also started his own jewelry line called D A V I.^[6] Cameron Losch, Lee McKinney and former guitarist Jason Richardson were all instructors on the music teaching website Bandhappy, which was owned by Matt Halpern, the drummer of Born of Osiris's former labelmate Periphery.

Following the unrevealing of "Glorious Day", Born of Osiris announced that they were in the process of developing a new EP entitled The Eternal Reign — a re-recording of The New Reign EP.
