Rudy Giuliani (1944-) served as the Republican mayor of New York City from 1994 until 2001. A prosecutor by trade, he presided over steep declines in both violent and quality-of-life crime. He was also widely praised for his leadership in the wake of the September 11, 2001, terrorist attack on the World Trade Center. Nonetheless, some New Yorkers opposed his abrasive style of governing. Giuliani ran for president in 2008 but dropped out after disappointing showings in the first few primaries.
