Nelson Rockefeller was governor from 1959 to 1973 and changed New York politics. He began as a liberal, but grew more conservative: he limited SUNY's growth, responded aggressively to the Attica Prison riot, and promulgated the uniquely severe Rockefeller Drug Laws. The World Trade Center and other profligate projects nearly drove New York City into bankruptcy in 1975. The state took substantial budgetary control, which eventually led to improved fiscal prudence.
