Former New York City Mayor David Dinkins has died at the age of 93. Dinkins was elected New York’s 106th mayor in 1989, defeating Republican challenger Rudy Giuliani to become the only African American ever to hold the position. During his four years in office, Dinkins expanded the size of New York’s police force to record levels. He also backed the movement against apartheid in South Africa, ordering the city to divest its pension fund from companies doing business there.
