, Yang di-Pertuan Besar IX of Negeri Sembilan. Late history covers the period of flux; after the fall of the Pagaruyung dynasty in west Sumatra and before the constitutional era.
Yamtuan Radin As the Pagaruyung Kingdom was in tatters in west Sumatra, Yamtuan Lenggang looked to continue the dynasty with what was left in Negeri Sembilan. He proposed his young son, Tunku Nasiruddin (Raja Radin/Raden), to be the next Yamtuan but the
Undangs were hesitant. After he died, there were five claimants to the throne: • Raja Kerjan (proxy for Sungai Ujong chief), • Raja Sati (Laboh) sent from Siak (also proxy for Sungai Ujong), • Raja Ali, nephew of Sultan Ibrahim of
Selangor • Raja Radin • Raja Beringin, self-appointed guardian of Radin. Raja Beringin was largely ignored; while Raja Sati bickered against his benefactor and was removed. In 1832, the Negri chiefs objected when Raja Ali declared himself Yamtuan and his son-in-law, Sayid Sha'ban as Yamtuan Muda. Ali and Sha'ban went to war with the
Linggi chief and attempted the murder of the
Undang of Rembau. The Negri chiefs abandoned their machinations, rallied around Raja Radin, elected him to the Seri Menanti throne and went to war against Ali and Sha'ban. Raja Ali was driven out; Sha'ban eventually became the
Tunku Besar (chief) of
Tampin; while Raja Kerjan was later killed by the Temenggong of Muar for stealing buffalo. The
Undang of Johol supported Tunku Antah; the
Undang of
Sungai Ujong was backing Tunku Ahmad Tunggal; the
Undang of
Jelebu was undecided with their own problems; the
Undang of
Rembau wanted their own independence. After 3 years of wrangling, Tunku
Antah was elected as Yamtuan in 1875. During this time, the British administration was attempting to obtain border treaties and commercial agreements with all the polities in the Malay Peninsula. The
Undang of Sungai Ujong signed with the British but without any reference to the ruler nor the other
Undangs. This eventually culminated into the 1876
Battle of Bukit Putus wherein the united forces of Negeri Sembilan attacked the British protecting Sungai Ujong. Yamtuan Antah's forces were eventually defeated by British infantry and artillery. Yamtuan Antah surrendered to the British in
Johor and was demoted to "Yamtuan Seri Menanti" but he was still determined to obtain an equitable agreement for the entire state. At the urging of the
Sultan of Johor, the
Governor of the Straits Settlements agreed to reconcile the dispute between Sungai Ujong and the other districts. Suggestions to the British from the
Undang of Sungai Ujong amongst others was the installation of a new Sultan (from Muar) and appointing Tunku Ahmad Tunggal as "Malay Captain" for all territories except Sungai Ujong. By 1877, every district and territory in Negeri Sembilan had separate agreements with the British which included arbitration by the Sultan of Johor; but this proved unworkable. In 1887, witnessed by the British Governor of the Straits Settlements, a new agreement was signed by the chiefs of Johol, Ineh, Ulu Muar, Jempol, Terachi and Gunung Pasir. Through this agreement, they acknowledge and ratify Yamtuan Antah as Yamtuan Seri Menanti; the ruler of the Seri Menanti Confederacy. Yamtuan Antah died in 1888, a victim of a
smallpox epidemic. ==Modern history==
