The arena was conceived by Bruce Ratner of real estate developer Forest City Ratner Companies, the New York division of Forest City Enterprises that Ratner founded.
He acquired the New Jersey Nets basketball team in 2004 for $300 million (he has since sold most of his shares to continue funding the project) for the purpose of moving them to the Pacific Park development on Brooklyn's Prospect Heights play in the arena that would be the centerpiece of the Pacific Park commercial and residential redevelopment project.
The move had marked the return of major league sports to Brooklyn, which had been absent since the departure of the Dodgers to Los Angeles in 1957.
Coincidentally, the original proposal for a domed stadium for the Brooklyn Dodgers was just north of the Pacific Park Brooklyn site, where the Atlantic Terminal Mall, also owned by Forest City Ratner Companies, is located.

The arena was initially projected to open in 2006, with the rest of the Pacific Park Brooklyn complex to follow.
However, controversies involving local residents, the use of eminent domain, potential environmental impact, lack of continued public financing, as well as a major economic downturn delayed the project.
Due to these legal and financial troubles, the development deal seemed headed towards failure or collapse.
Frank Gehry, an architect involved in the project's initial designs said, in March 2009, "I don't think it is going to happen," and Ratner at one point explored selling the team.
The New York Supreme Court ruled in favor of Ratner on May 16, 2009.
Opponents appealed the court decision.
A hearing for the appeal was scheduled for October 14, 2009, with a decision to be issued no sooner than November 25.

Russian businessman Mikhail Prokhorov agreed to a $200 million deal on September 23, 2009, to become a principal owner of the Nets and a key investor in the Brooklyn arena.

The Nets played two preseason games at Prudential Center in October 2009.
The two preseason games were successful, and a deal that would have the Nets play at the Prudential Center for the 2010–11 and 2011–12 NBA seasons became more likely.
Negotiations nearly fell apart, when the New Jersey Sports and Exhibition Authority refused to release the Nets from their lease at Izod.
Negotiations resumed, and on February 18, 2010, the Nets finalized a deal that would move them to the Prudential Center in Newark, New Jersey until Barclays Center opened.

The New York Court of Appeals ruled in favor of the state using eminent domain for the project on November 24, 2009.
Empire State Development Corporation Vice President Warner Johnston indicated that the agency was committed to seeing the project completed and said "we can now move forward with development."

Another potential roadblock to this development resulted from the Appellate Court's negative decision regarding a similar eminent domain case, brought against Columbia University.
This landmark case could have given new life to the case being brought by the community group Develop Don't Destroy Brooklyn (DDDB).

However, on March 1, 2010, Brooklyn Supreme Court Justice Abraham Gerges struck down a challenge by property owners, regarding the state's use of eminent domain, which allowed the private property to be condemned.
Groundbreaking for the project occurred on March 11, 2010.

The first concrete was poured into Barclays Center's foundation on June 29, 2010.
The arena began vertical construction on November 23, 2010, with the erection of the first steel piece.
The arena topped out on January 12, 2012, and was opened to the public on September 21, 2012.

Barclays Bank agreed to a 20-year naming rights agreement for $400 million in 2007.
However, two years later, due to the slump in the economy the deal was renegotiated to $200 million.

The New York Islanders of the National Hockey League (NHL) announced on October 24, 2012, that the franchise would move to Barclays Center in 2015 after the expiration of their lease at the Nassau Veterans Memorial Coliseum, which the team had called home since its inception in 1972.
