Consider the following dynasties:
1. Hoysala
2. Gahadavala
3. Kakatiya
4. Yadava
How many of the above dynasties established their kingdoms in early eighth century AD?
The dynasties listed in the question rose much later:
Hoysalas: Became independent rulers in the early 12th century.
Gahadavalas: Ruled parts of Uttar Pradesh and Bihar from the late 11th to the 12th century.
Kakatiyas: Started as subordinates of the Rashtrakutas and Kalyani Chalukyas, becoming independent in the late 12th century.
Yadavas of Devagiri: Also started as feudatories of the Kalyani Chalukyas and became independent in the late 12th century.
Therefore, none of them established their kingdoms in the early 8th century AD.
