Lord Duke is a minor character in Sleeping Beauty and major character in the first segment of Disney Princess Enchanted Tales: Follow Your Dreams. He is King Stefan and Queen Leah's fussy, but well behaved, majordomo and is in charge of making arrangements and keeping peace in the kingdom. Duke was voiced by the late Hans Conried in the original animated film and by Jeff Bennett in the first segment of Disney Princess Enchanted Tales: Follow Your Dreams.
Lord Duke appears to have a similar background to that of the Grand Duke from Cinderella; both characters appear as slender middle-aged men with black hair who work as head servants beside their respective kings and assist them in their politics and arrangements of their respective kingdoms.
Lord Duke makes a possible appearance as a minor background character, possibly as the royal herald in the beginning. At the christening birth of the infant princess Aurora, the herald that almost resembles Duke (same black hair and almost similar appearance, but only wearing blue and purple clothes and a yellow hat) is only seen when he announces the arrival of King Hubert and Young Prince Phillip. Duke's voice is heard again when he makes another announcement of the arrival of Flora, Fauna, and Merryweather.
After King Stefan and King Hubert discuss their plans about the future marriage of their respective children, Duke's voice is heard when he announces the arrival of Prince Phillip, who is arriving to see Hubert.
Duke's voice is heard one more time when he tells everyone that the sun has set and they are ready to welcome Aurora, unaware that she has touched the spindle of the spinning wheel by the orders of their enemy Maleficent. Afterwards, Lord Duke is not seen or heard of again for the remainder of the film.
Lord Duke appears in the first segment of Disney Princess Enchanted Tales: Follow Your Dreams, now voiced by Jeff Bennett. After King Stefan and Queen Leah told Aurora about ruling the kingdom while they attend the Royal Conference for King Hubert's speech, Stefan asked Duke about the arrangements for the Royal Conference. Duke assured that everything in the kingdom will run like clockwork and he bows down. But while doing so, he accidentally rips his breeches, revealing his pink-hearted boxers and runs to change his breeches, making Stefan and Leah laugh of what they saw at their embarrassed majordomo.
Later, Duke told Aurora about the signatures she needed to sign. She told him that her father said that the papers needed to be sign and that she was busy with the banquet and told him to hand her the first paper to read. However, Duke objected as he claims that it will take months and that reading won't be important because he told her to sign the forms. At first, Duke objected that they'll never get through all of the signatures, but Aurora advised him that they needed to show perseverance. Hearing of what Aurora said, Duke goes on the table and gets the first signed paper on top of the tower of papers, causing Aurora to catch it. But Duke sneezes and accidentally falls off the table, causing some papers to fall off, but organizes them back together. However, he sees the paper on top of the book shelf and grabs it, but the book shelf fell with him on the floor.
Recovering from the fall and after giving Aurora the document, he sees the paper on the edge of the castle window. He attempts to catch it, but he accidentally fell into the moat of the castle, screaming. Dripping wet, Lord Duke gave Aurora the document, which was actually the speech King Hubert forgot for the Royal Conference. Aurora needed someone to take the speech to Hubert, despite Duke complaining that they had only started the task.
Luckily, Flora, Merryweather, and Fauna arrive to do the task in delivering the document to Hubert for his speech at the Royal Conference. Before Merryweather gave Aurora the wand for extra help, Duke reminded Aurora that they have a great deal of work they have to do for the kingdom.
That evening, when Aurora is reviewing the signatures, Duke is seen sleeping.
The next morning, Lord Duke told Aurora that she will meet with the peasants. Later that day, Duke told Aurora that they should take a break, hoping that Stefan would understand. But Aurora determined not to give up, stating that her father told her about perseverance. However, when dealing with the redheaded farmer who wanted more chickens, she hesitated at the problem, but Duke told her about perseverance and goes to find the forms he forgot.
However, Aurora's magical inexperience leads to several consequences such as green pigs, enormous chickens, and cows. When Duke returned, he noticed the magic incident and a cow head-butts him. When Stefan, Leah, Hubert, Phillip, and Samson return home from the Royal Conference, Duke runs to the carriage and warns them about the green pigs, giant chickens, and cows. Not understanding of what Duke said, Stefan thought that he was going crazy, but Duke told them to see this incident at the throne room, immediately.
When Lord Duke, King Stefan, Queen Leah, King Hubert, and Prince Phillip arrive at the throne room, there were no giant chickens, green pigs, and cows, due to the problem being solved by Aurora. As Flora, Fauna, and Merryweather return from Hubert’s castle as well and Aurora giving the wand back to Merryweather, a confused Stefan asked Duke if he saw any cows and green pigs, but Duke told him that they’re all gone and he can’t understand about the magic incident.
Lord Duke is seen at the end of the first segment, where he is sitting next to Queen Leah at the royal banquet, alongside the two kings, the Three Good Fairies, Phillip, and Aurora, who told them about ruling a kingdom being both exciting and a challenge and that it is better to have them back. As they applauded at Aurora’s brief speech, Stefan and Hubert talks about “rumors” about giant chickens and cows as Phillip mentions green pigs, causing Duke, Leah, and the Three Good Fairies to laugh, along with the two kings and of course, Aurora.
