During a break in 1989, guitarist Adrian Smith released a solo album with his band [[ASAP (band)|ASAP]], entitled ''[[Silver and Gold (ASAP album)|Silver and Gold]].''{{sfn|Wall|2004|p=273}} Vocalist Bruce Dickinson also began work on a solo album with former [[Gillan (band)|Gillan]] guitarist [[Janick Gers]], releasing ''[[Tattooed Millionaire]]'' in 1990,{{sfn|Wall|2004|p=281}} followed by a tour.{{sfn|Wall|2004|p=285}} At the same time, to mark the band's 10-year recording anniversary, Iron Maiden released a compilation collection, ''[[The First Ten Years (boxed set)|The First Ten Years]]'', a series of 10 CDs and double [[12-inch single]]s. Between 24 February and 28 April 1990, the individual parts were released one by one, each containing two of Iron Maiden's singles, including the original B-sides.{{sfn|DDotB|2021}}

Iron Maiden then began work on a new studio record. During the pre-production stages, Adrian Smith left the band due to differences with Steve Harris regarding the direction the band should be taking. Smith disagreed with the "stripped down" style they were leaning towards.{{sfn|Wall|2004|p=283}} Janick Gers, having worked on Dickinson's solo project, was chosen to replace Smith and became the band's first new member in seven years.{{sfn|Wall|2004|p=285}} The album ''[[No Prayer for the Dying]]'' was released in October 1990.{{sfn|Prato}} It contained the hit singles "[[Holy Smoke (song)|Holy Smoke]]" and "[[Bring Your Daughter... to the Slaughter]]", the band's first – and, to date, only – [[UK Singles Chart]] number&nbsp;1, originally recorded by Dickinson's solo project for the soundtrack of ''[[A Nightmare on Elm Street 5: The Dream Child]]''.{{sfn|Wall|2004|p=282}} Iron Maiden's eighth studio album debuted at number&nbsp;2 on the UK albums chart{{sfn|Wall|2004|p=282}} and number&nbsp;17 on the ''[[Billboard 200]]''.{{sfn|Billboard}} ''No Prayer for the Dying'' was a return to their musical roots, especially in the simplicity of composition.{{sfn|DDotB|2021}}{{sfn|Wall|2004|p=283}} The No Prayer on the Road tour was booked for 120 shows in Europe, North America, and Japan. Thirty-three shows in continental Europe were sold out with a reported 530,000 fans attending.{{sfn|1990EU|2021}} In total, Iron Maiden played for some two million fans.{{sfn|Wall|2004|p=287}}{{sfn|1990EU|2021}}

After another break, the band recorded their next studio album, ''[[Fear of the Dark (Iron Maiden album)|Fear of the Dark]]'', which was released in 1992. The title track became a regular part of the band's concert setlists. Achieving their fourth number&nbsp;1 on the UK albums chart and number&nbsp;12 on the ''[[Billboard 200]]'',{{sfn|Billboard}}{{sfn|Wall|2004|p=289}} the release also included the number&nbsp;2 single "[[Be Quick or Be Dead]]", the number&nbsp;21 single "[[From Here to Eternity (Iron Maiden song)|From Here to Eternity]]", and the softer "[[Wasting Love]]".{{sfn|Wall|2004|pp=288–290}} The album featured the first songwriting by Gers, and no collaboration between Harris and Dickinson on songs. The [[Fear of the Dark Tour|extensive worldwide tour that followed]] included their first-ever Latin American leg, although Christian organisations prevented Iron Maiden from performing in Chile and accused them of being "emissaries of satanic propaganda",{{sfn|Brave Words & Bloody Knuckles|2011(2)}} and headlining the [[Monsters of Rock]] festivals in seven European countries.{{sfn|MOR1992|2021}} Iron Maiden's second performance at [[Donington Park]], for a sold-out audience of 75,000,{{sfn|FotDCDROM|2021}}{{sfn|Wall|2004|p=291}} was filmed for the audio and video release ''[[Live at Donington (Iron Maiden album)|Live at Donington]]'' and featured a guest appearance by Adrian Smith, who joined the band to perform "Running Free".{{sfn|Wall|2004|p=291}} The tour also saw conflicts between Bruce Dickinson and rest of the band.{{sfn|DDotB|2021}}{{sfn|DarkEra|2021}}

In 1993, Dickinson left the band to pursue his solo career, but agreed to remain for a [[Real Live Tour|farewell tour]] and two live albums (later re-released in [[A Real Live Dead One|one package]]).{{sfn|Wall|2004|p=293}} The first, ''[[A Real Live One]]'', was released in March 1993 and featured songs from 1986 to 1992, and the second, ''[[A Real Dead One]]'', was released after Dickinson left the band and featured songs from 1980 to 1984. The tour did not go well, with Steve Harris claiming Dickinson would only perform properly for high-profile shows, and that at several concerts, he would only mumble into the microphone.{{sfn|Wall|2004|p=296}} Dickinson denied he was under-performing, saying it was impossible to "make like Mr. Happy Face if the vibe wasn't right", and that news of his exit from the band had prevented any chance of a good atmosphere during the tour.{{sfn|Wall|2004|p=297}} Dickinson played his farewell show with Iron Maiden on 28 August 1993. The show was filmed, broadcast by the [[BBC]], [[MTV]] and released on video under the name ''[[Raising Hell (video)|Raising Hell]]''.{{sfn|Wall|2004|p=298}}
