A large popularity of Champagne is attributed to the success of Champagne producers in marketing the wine's image as a royal and aristocratic drink. Laurent-Perrier's advertisements in late 1890 boasted their Champagne was the favourite of Leopold II of Belgium, George I of Greece, Alfred, Duke of Saxe-Coburg and Gotha, Margaret Cambridge, Marchioness of Cambridge, and John Lambton, 3rd Earl of Durham, among other nobles, knights, and military officers. Despite this royal prestige, Champagne houses also portrayed Champagne as a luxury enjoyable by anyone, for any occasion. This strategy worked, and, by the turn of the 20th century, the majority of Champagne drinkers were middle class.
