Marie Antoinette was hated by nobles and commoners for many reasons.
Marie was a foreigner, when she got to France; she wasn’t trusted by the French court or her husband because of her origin.
She struggled to fit at the court. When she arrived, she was young and frivolous, she surrounded herself with a close group and she left out the established aristocrat hierarchy. They hated her for losing influence; they didn’t take it too kindly and started spreading rumour about her.
The people thought she was committing adultery, when her daughter and her first son were born, people believed them to be bastards from a duke or count.
She was popularly known as “Madame Deficit” because of her lavish spending habits on clothes and jewellery and she was highly criticized for it. She was greatly criticized throughout her time in France and during her trial she was also accused of having an incestuous relation with her son.
