The band then signed with Inside Out Music for the release of their 2015 album "Bloom". The band released their fourth album In Contact on 15 September 2017. In early 2011 Caligula's Horse was formed by Sam Vallen and Jim Grey. The band is named after the prized possession, Incitatus, of Roman Emperor Caligula by Grey, who is studying ancient history and classical languages at university. Initially
Holy Roman Emperor with very few exceptions, taken on a role as promoters and defenders of Christianity . The title of "Emperor" became defunct in Western Europe after the death of Julius Nepos in AD 480, although the rulers of the barbarian kingdoms continued to recognize the Eastern Emperor at least nominally well into the 6th century; both the title and connection between Emperor and Church continued in the Eastern Roman Empire until 1453, when it fell to the forces of the Ottoman Empire. In the west, the title of Emperor ("") was revived in 800, which also renewed ideas of imperial–papal cooperation.
