'''Emperor''' is, or was, a Norwegian BlackMetal band, founded in 1991 by Music/{{Ihsahn}}, Samoth, and Music/{{Mortiis}}. A number of bassists and drummers came and went during the band's existence, with Ihsahn (guitar, keyboards, vocals) and Samoth (guitar) forming the nucleus of the band. While they were officially active they released one demo, four full-length albums, a live album, and a handful of EP's and splits. In their early years Emperor was caught up in the turmoil and controversy of the Norwegian black metal scene of the early '90s, and following the recording of their first full-length album two members were arrested and imprisoned, Samoth for arson and drummer Faust for murder ([[AvertedTrope no jaywalking charges were reported]]). Samoth was released after 18 months, but Trym of Music/{{Enslaved}} replaced Faust, whose sentence was much longer. After this the band's criminal activities waned and they released three more albums before disbanding in 2001. The band reformed briefly in 2006-2007 for some live shows. In 2009 they released their second DVD/CD combo, a two-disc set culled from some festival performances, which they've said is [[TheVeryDefinitelyFinalDungeon "the final nail in the coffin"]] for the band. Despite this, the band announced that they would reunite once again to headline the Wacken and Bloodstock festivals in 2014, with Faust on drums. Trym has since rejoined the band.

The band is known for their melodic and symphonic take on black metal, bringing an element of complexity and epicness to the genre. They have been both lauded and scorned for their contributions in this regard by the black metal community. They continue to be one of the more popular bands from the second wave of black metal, having sold over half a million records since the foundation of the band. The members have had a number of other projects since the band's later days. While the band was still active Samoth and Trym started their death metal band Music/{{Zyklon}}, while Ihsahn and his wife Ihriel began their avant-garde project Peccatum. Both have since disbanded, and Ihsahn has recently released his fifth solo album in the ProgressiveMetal vein. Other projects include a punk band, an ambient classical album, another death metal band, and even a folk metal album. Previous members also found renown with other projects, such as Mortiis' solo project and Tchort's band Music/GreenCarnation.

!! Tropes common in Emperor's work include the following:

* AndThenJohnWasAZombie: And then Ihsahn was the Black Wizards.
* BlackMetal: I mean, what were you expecting? Emperor's early work is some of the most influential in the subgenre of symphonic black metal.
* CarefulWithThatAxe / MetalScream: Mandatory for a BlackMetal band.
** Ihsahn is practically one of the {{Trope Codifier}}s for the type 3 MetalScream. From ''Anthems'' onwards he started using type 1 as well. Secthdaemon predominantly uses type 2 and Einar Solberg uses all four.
* CoverVersion: The band covered Music/{{Bathory}}'s "A Fine Day to Die" and [[Music/KingDiamond Mercyful Fate]]'s "Gypsy". These show up as bonus tracks on the reissued ''In the Nightside Eclipse''.
* EarlyInstallmentWeirdness: Ihsahn's vocals on their early material (particularly ''In the Nightside Eclipse'') are very atypical, being generally more high pitched and screamy than his later vocals. On ''Anthems to the Welkin at Dusk'' he starts sounding more like he does now.
* EpicRocking: Prime examples include "The Tongue of Fire" (7:10), "With Strength I Burn" (8:17), and "Into the Infinity of Thoughts" (8:14, longer if the intro is included).
* IAmSong: "I Am the Black Wizards", though not in an at all conventional sense.
* IAmTheBand: Ihsahn and Samoth are the only constant members of Emperor.
* MohsScaleOfRockAndMetalHardness: Usually about a 9, but some of their music dips into an 8, probably including most of ''Prometheus'' (the prog influences drag it down a bit), and some of the earlier material may hit 10 due to the more abrasive production. The instrumental "The Wanderer" may be a 7, but it's a bit of an oddity in their discography. "Opus a Satana", not containing prominent guitars, is not really classifiable.
* NewSoundAlbum: Each of their albums was more symphonic and less typical of black metal than its predecessor. ''Anthems to the Welkin at Dusk'' greatly increased the production value over the razor-thin sound found on ''In the Nightside Eclipse'' (of course, there are plenty of fans who will argue that the production on that album was absolutely perfect for the material found on it), and also substantially increased the symphonic influence on the music. ''IX Equilibrium'' departed even further from the standard black metal sound, and ''Prometheus'' was arguably no longer even recognizable as black metal, just being progressive metal with harsh vocals.
* OurTrollsAreDifferent: Mortiis' troll gimmick, which carried over into his solo project.
* ProgressiveMetal: The prog influence on Emperor's work got progressively stronger with each album, to the point that ''Prometheus'' was arguably more of a prog album than a black metal album. Disagreement on the band's direction (Samoth and Trym wanted to go in a more stripped-down, IndustrialMetal-influenced direction) was a large part of the reason they split up.
* SiameseTwinSongs: "Alsvatr (The Oath)" and "Ye Entrancemperium".
* [[LadyNotAppearingInThisGame Sir Not-Appearing-On-This-Tape]]: Tchort appears on the cover of ''Wrath of the Tyrant'' but doesn't play on it.
* SopranoAndGravel: Ihsahn does the expected MetalScream typically found in black metal, but he also does clean singing (it's worth noting that he's a classically trained vocalist). He often backs himself up, creating surprisingly sophisticated harmonies seldom found in black metal (their fellow countrymen Music/{{Enslaved}} are one of the few other black metal acts that use similar vocals).
* StartMyOwn: Ihsahn went solo while Samoth and Trym formed Music/{{Zyklon}} when they broke up in 2001.
* SurprisinglyGentleSong: "The Wanderer", the instrumental closer to ''Anthems to the Welkin at Dusk'', as well as "Opus a Satana", a keyboard-based remake of ''In the Nightside Eclipse''[='=]s "Inno a Satana". "Alsvatr (The Oath)" could also be considered an example, although since it leads into "Ye Entrancemperium", which is not at all an example of this trope, it could also be considered a subversion.
* SymphonicMetal: TropeCodifier for the BlackMetal section of the genre.
* TokenGoodTeammate: Ihsahn, who is the only performer on ''In The Nightside Eclipse'' who wasn't sent to prison for one reason or another.
* UncommonTime: "An Elegy of Icaros" has one riff where it's pretty much impossible to find two consecutive measures in the same meter signature (it can be heard starting at 1:04 and at the end of the song). There are segments of "Sworn" that do the same thing (one of them starts at 1:51). This also shows up in several songs on ''Prometheus'', like "The Tongue of Fire" and "He Who Sought the Fire".
* VocalEvolution: See EarlyInstallmentWeirdness above.
