The Politico-Militar Distrito de Morong or Distrito de Morong was a province in the Philippines created out of the province of Manila and a part of Laguna on February 23, 1853 by a decree of the Superior Gobierno, composing Morong, Pililla, Tanay, Baras, Binangonan, Jalajala, Angono and Cardona from Laguna; and Antipolo, Boso-Boso, Cainta and Taytay from Manila. The offices were housed at a building now known as Commandancia. Its first military governor was Francisco Turrentigue.
Three years after the issuance of Royal Decree of Spain in 1844, provincial organizations were reclassified into provinces, districts, and politico-military units. At that time, the province of Manila had religious jurisdiction over Pueblo de Morong and Laguna over all governmental, commercial, industrial and social affairs. Politico-Militar Distrito de Morong was created out of these provinces. It took its name from the capital village Morong, located at the shore of the Laguna de Bay, with villages under the supervision of the Franciscans.
The following is a list of the pueblos comprising Distrito de Morong.
On February 11, 1879, the creation of the town of Teresa was approved, merging the four former sitios of the town of Morong, namely, Santa Rosa, Prinza, Pantay and Buhangin.
Before the outbreak of the Philippine Revolution, a branch of the Katipunan was created in Morong, the capital of the district. Many leaders of the Katipunan were from Distrito de Morong. Among the very first initiates of the Katipunan was Aurelio Tolentino who hailed from Morong. He and his brother Jacinto were Andres Bonifacio's agents. Teodoro Plata, one of original founding members, was a clerk in the Court of Justice of the Peace of Morong.
