(CNN) While celebrating her victory in becoming the first African-American woman picked to lead Chicago, Lori Lightfoot thanked the city and those who blazed the trail for her victory.

"We may be strangers but in this room, in this city we are all neighbors," she told a cheering crowd following her win.

Lightfoot faced a historic runoff Tuesday against Toni Preckwinkle, who is also an African-American woman.

"Now that it's over I know that we will work together for the city that we both love," Lightfoot said at her campaign celebration. "Today you did more than make history, you created a movement for change."

She told her followers they were going to remake Chicago, home to 2.7 million people.
