The Paramaras established a powerful kingdom with their capital at:

Dhar
Ujjain
Vidisha
Gwalior

The correct answer is: A) Dhar.

The Paramaras were a Rajput dynasty that ruled over parts of central India from the 9th to the 13th centuries. They were founded by Vakpati Munja, who conquered the Malwa region in the 9th century. The Paramaras reached their peak under the rule of Raja Bhoja, who reigned from 1010 to 1055 CE. Bhoja was a powerful and successful ruler who expanded the Paramara kingdom and patronized the arts and sciences. He is also known for his Sanskrit writings on a variety of subjects.

The Paramara capital was at Dhar, a city in the Malwa region. Dhar was an important center of trade and culture during the Paramara period. The city was also home to a number of temples and palaces.

The Paramara dynasty declined in the 13th century, following a series of defeats by the Delhi Sultanate. The last Paramara ruler, Jayasimha III, was defeated by Alauddin Khalji in 1293 CE. The Paramara kingdom was subsequently annexed by the Delhi Sultanate.

The Paramaras were a significant dynasty in the history of India. They were a powerful and successful ruling family who left a lasting legacy on the Indian subcontinent.

The other options are incorrect because:

  • Ujjain was the capital of the Malwa Pratiharas, a previous dynasty that ruled over the Malwa region.
  • Vidisha was an important city during the Paramara period, but it was not the capital of the dynasty.
  • Gwalior was not founded until the 11th century, after the peak of the Paramara dynasty.
