ACE Limited was established in 1985, funded by a group of 34 U.S. companies seeking difficult to obtain excess liability and directors and officers insurance coverage. That year, ACE and its Bermuda subsidiary, incorporated in the Cayman Islands and headquartered in Hamilton, Bermuda, wrote its first insurance policy with John Cox as its President and CEO. In 1987 the company assumed management of Corporate Officers & Directors Assurance Limited (CODA), expanding ACE Bermuda's product line.
Walter Scott became Chairman, President, and CEO of ACE in 1990 and saw the company listed on the New York Stock Exchange in 1993. Brian Duperreault succeeded Scott in 1994 as Chairman, President & CEO and worked for the next ten years as ACE went through a series of acquisitions and a diversification process that brought the ACE Group of Companies global status. One of the multiple acquisitions made during this time was the global property and casualty business of Cigna Corporation, formerly the Insurance Company of North America, or INA, which was purchased for $3.45 billion in 1999.
In 2004 Evan G. Greenberg became President and CEO of ACE Ltd. In 2004 ACE was also investigated by NY Attorney General Eliot Spitzer for participating in a bid rigging and price fixing scheme with insurance broker Marsh & McLennan.
In 2008, ACE purchased the accident and health insurance provider Combined Insurance Company of America (founded by W. Clement Stone in 1919) from Aon Corporation for $2.56 billion and the high net worth personal lines business of the Atlantic Companies.
Also in 2008, ACE relocated from the Cayman Islands to Zurich, Switzerland. Evan Greenberg described the move as a "natural progression" that would provide ACE with a "better strategic flexibility…and a solid legal and regulatory environment…" The re-domestication was completed in July that year.
In 2010, ACE Limited purchased Rain and Hail, LLC for $1.1 billion. Rain and Hail Insurance Service, headquartered in Johnston, Iowa, is an industry leader in crop insurance in the United States.
In 2011, ACE Limited purchased agribusiness insurer Penn Millers. 
During 2012, they purchased Indonesian insurer Asuransi Jaya Proteksi. 
ACE under investigation
2004 Eliot Spitzer investigation
In 2004 New York Attorney General Eliot Spitzer conducted an investigation in the insurance industry. ACE, American International Group (AIG), Marsh & McLennan, and other large insurers and brokerages were named in Spitzer's investigation for possibly participating in questionable insurance practices including the payment of contingent commissions, bid-rigging, price-fixing, and improper accounting. 
Spitzer asserted that contingent commissions contributed to a widespread practice of "bid-rigging" where brokers solicited fake bids with deliberately less favorable terms for the consumer than the bid offered by the insurance company paying the highest commissions.
As part of an $80 million settlement that abated further inquiry, ACE signed an Assurance of Discontinuance in which they acknowledged their prior conduct and agreed to alter their business practices. Evan Greenberg himself admitted no fault in Spitzer's allegations although a junior executive did plead guilty to criminal charges.
Spitzer's insurance industry probe additionally looked in early 2005 into ACE Ltd's subsidiary ACE Tempest Re's reporting to the SEC of a series of reinsurance transactions, together with the SEC reporting of a further 16 unaffiliated reinsurers. Evan Greenberg said that his company's investigation should be completed within a month. According to Greenberg, contracts appeared "generally structured in a way to provide for appropriate risk transfer and accounted for properly."
The Spitzer investigations also triggered civil litigation by policyholders who claim they were victimized by the bid rigging and commission schemes.
