JPMorgan Chase's corporate headquarters are in New York City. Our retail financial services and commercial banking headquarters are in Chicago. Our major legacy institutions- J.P. Morgan, Chase Manhattan, Chemical, Manufacturers Hanover, Bank One, First Chicago, and National Bank of Detroit- contributed significantly to the development of communities worldwide. Our corporate history is intertwined with innovations in finance and the globalization of the world economy.

Key transactions leading up to the formation of JPMorgan Chase include the following:

• In 1991, Chemical Banking Corp. combined with Manufacturers Hanover Corp.,  keeping the name  Chemical Banking Corp., then the second-largest banking institution in the United States.
• In 1995, First Chicago Corp. merged with National Bank of Detroit's parent NBD Bancorp., forming First Chicago NBD, the largest banking company based in the Midwest.
• In 1996, Chase Manhattan Corp. merged with Chemical Banking Corp., creating what was then the largest bank holding company in the United States.
• In 1998, Banc One Corp. merged with First Chicago NBD, taking the name Bank One Corp. Merging subsequently with Louisiana's First Commerce Corp., Bank One became the largest financial services firm in the Midwest, the fourth-largest bank in the U. S. and the world's largest Visa credit card issuer.
• In 2000, J.P. Morgan & Co. merged with Chase Manhattan Corp., in effect combining four of the largest and oldest money center banking institutions in New York City (J.P. Morgan, Chase, Chemical and Manufacturers Hanover) into one firm called J.P. Morgan Chase & Co.

These mergers culminated in July 2004 with the joining of J.P. Morgan Chase & Co. and Bank One Corp. to form today's JPMorgan Chase &Co. Fortune magazine said "the combined bank will be big and strong in a panoply of businesses," adding that "the deal has been widely lauded" by investment analysts. The New York Times  said the merger "would realign the competitive landscape for banks" by uniting the investment and commercial banking skills of J.P. Morgan Chase with the consumer banking strengths of Bank One.
