When did people stop using candles?

People didn't entirely stop using candles; rather, their usage diminished with the advent of electric lighting in the late 19th and early 20th centuries. The widespread adoption of electric lights, particularly in homes and public spaces, reduced the reliance on candles for illumination. However, candles remain popular for decorative purposes, ambiance, and fragrance, and they continue to be used in various cultural and religious practices.
