The history of scented candles dates back thousands of years, with evidence of early candle-like devices being used in ancient Egypt and China. However, it wasn't until the Middle Ages in Europe that scented candles as we know them today began to emerge. Monks in medieval Europe were known to infuse beeswax candles with aromatic resins and herbs for use during religious ceremonies, and the practice soon spread to the nobility and affluent households. The 19th century saw a significant advancement in candle-making techniques with the introduction of paraffin wax, which allowed for more affordable and consistent production of scented candles. In the modern era, scented candles have become a ubiquitous feature in homes, offering a wide range of fragrances to create ambiance and evoke emotions.
