The Revolutionary Government of the Philippines (Spanish: Gobierno Revolucionario de Filipinas) was a revolutionary government established in the Spanish East Indies on June 23, 1898, during the Spanish–American War, by Emilio Aguinaldo, its initial and only president. The government succeeded a dictatorial government that had been established by Aguinaldo on June 18 and was dissolved and replaced by this government upon its establishment. This government endured until January 23, 1899, when the proclamation of the Malolos Constitution established an insurgent Philippine Republic government that replaced it.

The Sultanate of Brunei (Jawi: كسلطانن بروني) or simply Brunei (broo-NY), also known as the Bruneian Empire, was a Malay sultanate centered around Brunei on the northern coast of Borneo in Southeast Asia. Brunei became a sovereign state around the 15th century, when it substantially expanded after the fall of Malacca to the Portuguese, extending throughout coastal areas of Borneo and the Philippines, before it declined in the 17th and 18th centuries. It became a British protectorate in the 19th century.

The Philippine Republic (Spanish: República Filipina), now officially remembered as the First Philippine Republic and also referred to by historians as the Malolos Republic, was an insurgency established in Malolos, Bulacan, during the Philippine Revolution against the Spanish Empire (1896–1898) and the Spanish–American War between Spain and the United States (1898) through the promulgation of the Malolos Constitution on January 23, 1899, succeeding the Revolutionary Government of the Philippines. It was formally established with Emilio Aguinaldo as president. It was unrecognized outside of the Philippines but remained active until April 19, 1901.

The Sultanate of Buayan (Maguindanaon: Kasultanan nu Buayan, Jawi: كسولتانن نو بواين; Filipino: Sultanato ng Buayan) was a Muslim state on the island of Mindanao in the southern Philippines from the mid-14th to the 20th century. Buayan was one of the four major sultanates in Mindanao, other sultanates being the Sultanate of Sulu, the Sultanate of Maguindanao, and the Confederate States of Lanao. Being the primary power in the upper Cotabato valley, it had access to an abundance of fertile land as well as raw materials, transforming into an agricultural powerhouse in contrast to Maguindanao. In addition, despite its status as an interior sultanate, Buayan was able to conduct maritime trade and diplomacy either through the Pulangi River mouth, or its port in Sarangani. At its maximum extent, its territory stretched from modern-day Kabuntalan to Sarangani Bay.
