In 1874, the British intervened militarily in a leadership tussle in Sungai Ujong to preserve British economic interests, and placed the domain under the control of a British Resident. Jelebu followed in 1883 and Rembau in 1887. The formation of modern Negeri Sembilan began in 1889, when the Seri Menanti domain, under the rule of Tuanku Muhammad (son of Yamtuan Antah), combined with the domains of Tampin and Rembau, forming the "Seri Menanti Confederation" as a single political entity. The domains of Sungai Ujong and Jelebu joined this confederation in 1895, forming the state of Negeri Sembilan in its modern borders. Martin Lister became the new state's first Resident, and Negeri Sembilan became part of the Federated Malay States the same year.
