The Rīsthal inscription is a stone-slab inscription which was discovered in 1983 in the area of Rīsthal near Mandsaur in Madhya Pradesh, India.
The inscription says that in 515 CE the Aulikara king Prakashadharma of Malwa defeated the Alchon Huns ruler Toramana in his campaigns into Central India, and took away the tusks of his elephants and his harem.
The Aulikaras (Late Brahmi script: 
Au-li-ka-rā), were an ancient clan that ruled the Kingdom of Malwa between 350 and 575.
Epigraphical discoveries have brought to light two royal lines, who call themselves as the Aulikaras and ruled from Dashapura (present-day Mandsaur). The first royal house, which ruled from Dashapura comprised the following kings in the order of succession: Jayavarma, Simhavarma, Naravarma, Vishvavarma and Bandhuvarma. The Rīsthal stone slab inscription discovered in 1983 has brought to light another royal house, which comprised the following kings in the order of succession: Drumavardhana, Jayavardhana, Ajitavardhana, Vibhishanavardhana, Rajyavardhana and Prakashadharma, who defeated Toramana. In all probability, Yashodharman also belonged to this house and he was the son and successor of Prakashadharma. Yashodharma defeated Mihirakula and freed the Malwa region from the Hunas. The rule of the Aulikaras over Malwa ended with him.
