Sajjan Singh came to the throne when he was 15 years old. However, his uncle Sohan Singh challenged his right to the crown and even plotted through astrologers, who said the timing for the coronation was not appropriate. Fortunately for him the then British agent, who was in favour of Sajjan Singh, intervened and persuaded the astrologers to give a favourable date for the crowning. The eventual Coronation of Sajjan Singh took place two years after this. As the trouble-maker uncle was still persisting with his obstructions towards the newly crowned Maharana, his property was confiscated and he was eventually imprisoned.
