Chicago Mayor Rahm Emanuel has tapped Sophia King to become the new 4th Ward alderman. 

Former 4th Ward Ald. Will Burns stepped down earlier this year to work at the room letting website Airbnb.

Emanuel announced King's appointment to the Chicago City Council on Monday.

"For almost 30 years, Sophia King has not just lived in the 4th Ward, she has worked to improve the quality of life for everyone who lives there," the mayor said in a statement. "She has led initiatives to increase education, recreation, employment and safety, as well as quality affordable housing. She will be a tireless advocate for her constituents as she serves on City Council."

King is president and a founding member of the non-profit Harriet's Daughter, which "works collectively with peer organizations to advocate for, create and support policies and processes that secure employment and wealth creation opportunities for African-American communities," according to its website. 

"I'm ready to roll up my sleeves and get to work. I believe the only solutions we are missing are the ones we won't work on together," King said. "I look forward to collaborating with all people who want to make a positive difference in the city that I love, and to continue to position the 4th Ward as an example of transparent, innovative and community focused work that lifts all residents. I appreciate the confidence of Mayor Rahm Emanuel and his willingness to engage a new voice."

The Chicago City Council will have to confirm King's appointment. 

Also on Monday, Ald. Howard Brookins Jr. (21st) was named the city council's new education committee chairman, a position formerly held by Burns.
