In 1970 the Bank of Boston reorganized under a new holding company, First National Boston Corporation, and began a series of acquisitions of regional banks through the 1970s and 1980s. In 1978, the bank challenged a Massachusetts law limiting bank contributions to political issues. The U.S. Supreme Court sided with the bank that their First Amendment rights were being restricted, in "First National Bank of Boston v. Bellotti". In 1982, the bank renamed itself Bank of Boston. In 1985 Bank of Boston acquired Connecticut-based Colonial Bancorp and in 1987 acquired BankVermont Corporation.
