Santander Bank, N. A., formerly Sovereign Bank, is a wholly owned subsidiary of the Spanish Santander Group. It is based in Boston and its principal market is the northeastern United States. It has $57.5 billion in deposits, operates about 650 retail banking offices and over 2,000 ATMs, and employs approximately 9,800 people. It offers an array of financial services and products including retail banking, mortgages, corporate banking, cash management, credit card, capital markets, trust and wealth management, and insurance. Sovereign Bank was rebranded as Santander Bank on October 17, 2013; the stadium, arena, and performing arts center for which it has naming rights were also rebranded. Santander Bank, N.A., was founded in 1902 as "Sovereign Bank", a savings and loan in Wyomissing, Pennsylvania. The company's earliest customers were largely textile workers. Sovereign expanded rapidly during the savings and loan crisis of the 1980s and 1990s, acquiring numerous other banks. In 2000, Sovereign bought 278 New England branches from the newly merged FleetBoston Financial, becoming the third-largest retail bank in the Boston area at one stroke. This transaction was driven by a requirement from bank regulators that Fleet Bank and BankBoston divest 306 branches as a condition for merger. Forty-five years before the founding of Sovereign Bank, its future parent was founded as Banco Santander on 15 May 1857, with the approval of Queen Isabel II of Spain. The bank grew and in the 1920s started to build a network of branches. In 1942 it opened in Madrid. In 1934 Emilio Botín Sanz de Sautuola y López became director, and in 1950 chairman. He expanded the bank throughout Spain, so in 1957 it was Spain's seventh-largest bank. In 1976 it acquired First National Bank of Puerto Rico, and in 1982 Banco Español-Chile. In 1986, Emilio senior's son, Emilio Botín Sanz de Sautuola y García de los Ríos, succeeded him. In the late 1980s he acquired CC-Bank in Germany and a stake was in Banco de Comercio e Industria in Portugal. In 1989, the "Supercuenta Santander" was launched.
