Muhammad II ascended the throne after a violent succession struggle. Early in his reign Kelantan was torn by a civil war among rival princes. In 1838 the British envoy
Munshi Abdullah was recorded to deliver Governor
Samuel George Bonham's letters to Kelantanese chiefs including the Sultan and other leading rajas to relieve boats containing valuable merchandise owned by Singaporean merchants, the letter confirmed that the boats were stranded due to an ongoing civil war there. The civil war drew Siamese intervention and in 1839 King
Rama III's envoy Phraya Siphiphat who mediated peace between Sultan Muhammad II and his rival Tuan Besar, eventually relocating Tuan Besar to govern
Pattani in 1842. Siam thereafter formally recognized Long Senik as ruler (conferring on him the noble title
Phaya Wiset Baktiya in 1836) and in later years elevated his rank under King
Rama V. == Reign ==
