Unfortunately, Chulalongkorn and his brothers (the "Young Siam" group) were at the same time trying to consolidate his own authority and return to the Grand Palace the power it had lost since the death of his father. Spurred on by their Western education, Young Siam was intent on creating a centralized and strong nation under an absolute monarch. To achieve this goal, Chulalongkorn needed to implement radical reforms in all parts of the Royal Government. In 1873 the king established the 'Auditing Office' (หอรัษฎากรพิพัฒน์, now the Ministry of Finance). It was created to modernize and simplify the collection of state revenues and taxes to the treasury. At the same time, however, it deprived the control of nobility (as landowners) over tax farms, which for generations had constituted a large part of their income. The following years the king by Royal Decree created the 'Privy Council of Siam' (สภากรรมการองคมนตรี). Copied from the European tradition, the council was an effort by the king to shore up his own legitimacy and to create an elite he could rely on. In their inauguration speeches, the forty-eight councilors pledged allegiance to the Monarch and his heirs. These reforms infuriated the conservative faction at court, the "Old Siam" composed mainly of old aristocratic families, as the financial reforms eroded some of their old privileges. Politically the creation of the Privy Council meant that only royal favourites had access to political offices, depriving the old families of their influences. This group included Vichaichan, whose role in the finance and the government of the kingdom was slowly being eroded. Conflict between the opposing sides seemed inevitable. Vichaichan had the support of the British Consul-General to Siam, Thomas George Knox. He was originally recruited by Pinklao to modernize the Front Palace's armed forces. After Mongkut's death, Knox greatly preferred the mature and experienced Vichaichan — who was also the son of one of the most westernized member of the elite to ascend the throne — over the young, unknown and radical Chulalongkorn. In early December 1874, Vichaichan received an anonymous letter threatening his life.
