London Breed was sworn in on Wednesday as the first black female mayor of San Francisco.

The San Francisco native succeeds former Mayor Ed Less, whose death in December 2017 prompted a special election last month for a replacement to serve the remainder of his term.

Breed, 43, won more first-place votes than any other candidate running in the June primary.

The election was the first time in San Francisco that voters elected a new mayor using the ranked-choice format.

Breed, who previously served as San Francisco Board of Supervisors president for three years, thanked her colleagues for their dedication and vowed to continue working with them in her new role.

“And what I noticed about this board, and what made me so proud to be a part of it is, we stand our ground, we do what we think is best and we try to fight for the people we represent.” 

The Rev. Amos C. Brown, president of the San Francisco branch of the NAACP, praised Breed’s election to the publication and said her inauguration will show “a quintessential picture of how America can become a more perfect union.” 

San Francisco has one of the smallest black populations among major U.S. cities, with just about 6 percent of its 870,000 population accounting for its black residents. Those numbers are reportedly decreasing.
