What was the desire that queen rajyalaxmi wanted to fulfil with the help of gagan singh

Rajya Lakshmi Devi (Nepali राज्यलक्ष्मी देवी) (ca. 1814– before 1900) was a Queen consort of Nepal as the junior wife of King Rajendra of Nepal. [1] In 1843, Queen Rajya Lakshmi was made the queen regent. An ambitious woman, Queen Rajya Lakshmi wanted to have her son, Prince Ranendra, to be crowned the next king instead of her stepson, Surendra. She was somewhat responsible for the Kot massacre in 1846, which initiated the 104-year rule of the Rana dynasty in Nepal.
