Peter Moores has been named as England's new head coach.
The 51-year-old returns to the role he left in 2009, having spent the last four seasons as head coach at Lancashire.
During that time he led the County to the County Championship division one title in 2011 and then led them to promotion back to the top-flight last season after they were relegated in 2012.
In a statement on the England and Wales Cricket Board website, managing director Paul Downton said: "Peter has a great reputation around the world as an outstanding coach and he will return to the role as England head coach with a great deal more experience and understanding of the challenges that the role presents.
"There is no doubt that he is the leading English coach of his generation and I believe that this is his time.
"His domestic credentials are beyond reproach having won the County Championship at Sussex and then repeating the feat at Lancashire, whose 2011 triumph was their first for 77 years.
"He was also the lead at the National Cricket Performance Centre at Loughborough between 2005 and his appointment as England coach in 2007.
"In his time with England he gave Test debuts to Stuart Broad, Matt Prior and Graeme Swann as well as helping to further the international careers of players like the current England captain Alastair Cook and James Anderson.
"He also brought Andy Flower into the England set-up as well as influential individuals like Mushtaq Ahmed as spin bowling coach.
"I was hugely impressed by his vision for the future of the England team and I am looking forward to working with him in the years to come."
Limited-overs coach Ashley Giles was initially strong favourite to take the reins, after Andy Flower resigned as team director in January in the aftermath of England's Ashes whitewash in Australia.
But a series of miserable performance from Giles' charges, with only five wins in 18 ODIs and T20 games in 2014, saw his stock plummet.
In the ECB statement, Downton paid tribute to Giles, saying: "I would personally like to thank Ashley Giles for the job he did with the limited-overs squads in the last 18 months.
"It was a really difficult decision to make as we had an outstanding field but the panel were unanimous in the choice of Peter and I know that support will be echoed around the counties."
Moores was first named England head coach in April 2007 and he oversaw the team for 22 Tests, of which eight were won, six lost, and eight drawn.
However, following Test and one-day series losses in India, it emerged in January 2009 that Moores and Pietersen were in dispute.
Moores was removed as coach that month and Pietersen resigned as captain, although he continued as a player and has suggested subsequently that the removal of Moores was to the benefit of the side.
The 51-year-old Moores took up a post as coach of Lancashire in February of that year and led them to the County Championship title in 2011, their first for more than 70 years.
They were surprisingly relegated the following season but bounced straight back, winning the second division title last year.
Downton said the ECB are in advanced negotiations to appoint an assistant coach but refused to name the individual "out of respect to his current employers".
England's next fixture is a one-day international against Scotland in Aberdeen on 9 May.
Sri Lanka coach Paul Farbrace is expected to be named as Moores' assistant but the ECB would not confirm this, saying only that they are in advanced negotiations with "an individual."
