Question

what did duryodhana and his aides do to trouble king virata​

Answer 1

Virata in the Hindu epic Mahabharata, was the king of Virata Kingdom, in whose court the Pandavas spent a year in concealment during their exile.

Virata was married to Queen Sudeshna and was the father of Prince Uttara and Princess Uttarā, who married Abhimanyu, the son of Arjuna.

Abhimanyu and Uttara's son Parikshit succeeded Yudhishthira to the throne of Hastinapura, after the war of Mahabharata.

He was killed during a Kauravas attack in the Kurukshetra War along with his sons. In other versions he is killed by Drona on the 15th day of the war.
