Emerging from a crowded six-candidate field, Gibson was elected in a runoff election in 1970, defeating incumbent mayor
Hugh Addonizio. At the time Gibson noted that "Newark may be the most decayed and financially crippled city in the nation." He entered office as a reformer, alleging that the prior administration was corrupt. Later that same year, Mayor Addonizio was convicted of
extortion and
conspiracy. Gibson was also a representative of the city's large African-American population, many of whom were migrants or whose parents or grandparents had come North in the
Great Migration. The city's industrial power had diminished sharply.
Deindustrialization since the 1950s cost tens of thousands of jobs when African Americans were still arriving from
the South looking for better opportunities than in their former communities. Combined with forces of suburbanization and racial tensions, the city encountered problems similar to those of other major industrial cities of the North and Midwest in the 1960s - increasing poverty and dysfunction for families left without employment. The city was scarred by
race riots in 1967, three years before Gibson took office. Many businesses and residents left the city after the riots. Gibson's election was seen by some in almost prophetic terms. Poet and playwright
Amiri Baraka wrote, "We will nationalize the city's institutions, as if it were liberated territory in Zimbabwe or Angola." Gibson himself said, "Wherever American cities are going, Newark will get there first". Gibson entered and with his new city council "challenged the corporate sector's tax arrangements and pushed business interests to take a more active and responsible role in the community." By 1974, Gibson had alienated some of his supporters in his efforts to keep businesses from leaving the city. Amiri Baraka then labeled him a "neo-colonialist" and complained that Gibson was "for the profit of
Prudential, Public (private) Service,
Port Authority, and other huge corporations that run in and around and through and out of Newark paying little or no taxes" while the residents were ignored. He was reelected in 1974. In 1976, Gibson became the first African-American president of the
United States Conference of Mayors. He served as president from 1976 until the next year. In 1979, Gibson received the U.S. Senator
John Heinz Award for Greatest Public Service by an Elected or Appointed Official, an award given out annually by the
Jefferson Awards. After 16 years under Gibson, the city’s unemployment rate had risen nearly 50 percent, its population had continued dropping, it had no movie theaters, only one supermarket remained, and only two-thirds of its high school students were graduating. In 1986, fellow Democratic challenger,
Sharpe James, defeated Gibson in his attempt to be reelected for a fifth term. == Later life ==
