Julian Castro was born on September 16, 1974, along with his twin brother, in San Antonio, Texas, where his family has lived since the 1920s. He was always a brilliant student, attending both Stanford University and Harvard Law School. Upon his graduation from law school, Castro ran for a seat on the San Antonio City Council and won, making history as the youngest councilman in the city’s history.
He served for several years and then ran for the mayoral seat, which he lost. He ran again for the mayoral seat in 2009 and won, becoming the fifth Hispanic mayor in San Antonio’s history. Castro was relatively unknown before he delivered the keynote address at the Democratic National Convention in Charlotte, North Carolina in September 2012.
