Before 1799, Pateros was only a barrio of Pasig until the Spanish Governor-General of the Philippines issued a decree making Pateros an independent municipality. The town was then composed of five barrios (villages): Aguho, San Roque, Santa Ana, Santo Rosario (Santo Rosario-Silangan and Santo Rosario-Kanluran), and Mamancat (now part of Fort Bonifacio).

During the Philippine–American War in March 1899, the first contingent of American Volunteers from Washington arrived in the town of Pateros. The American soldiers rallied and eventually won the battles to take control and establish a temporary camp.

Throughout this period, American soldiers were able to experience the culture and livelihood of the citizens of Pateros. Having roast duck for meals during wartime and sending postcards of Pateros back to the United States of America. In 1900, a member of the American contingent, Lieutenant Charles Nosler, renamed the city of Ive's Landing in Washington State, USA, after the town of Pateros in the Philippines. Pateros in Washington State officially became an American city on May 1, 1913.[7]

On March 29, 1900, Pateros, then a part of the province of Manila, became one of the towns in the newly created province of Rizal, by virtue of General Order No. 40, Act No. 137 of the Philippine Commission, which was promulgated on June 11, 1901.[8] Then on October 12, 1903, Act No. 942 united Pateros with Taguig and Muntinlupa into one municipality under Pateros.[9] Muntinlupa was later separated from Pateros on November 25, 1903 to become part of Biñan, La Laguna through Act No. 1008.[10] The municipality was renamed Taguig and Muntinlupa was reconsolidated with it on March 22, 1905 through Act No. 1308.[11]

Executive Order No. 20 dated February 29, 1908, partitioned Pateros from Taguig, and the town regained independent status as a municipality on January 1, 1909, by Executive Order No. 36.

On November 7, 1975, Pateros became a part of the new Metropolitan Manila Area through Presidential Decree No. 824.[12][13]

On July 23, 2013, Mayor Jaime C. Medina visited the city of Pateros, Washington State, United States to sign the Sister City Memorandum of Understanding between the Municipality of Pateros, Metro Manila and Pateros City of Okanogan County, Washington State, USA. According to Mayor Gail Howe, the two cities have not applied through Sister Cities International but the goals of promoting the culture and exchanges have turned the sisterhood into reality.[14][15]

In 2011 and 2014, Arnel Cerafica, the then-representative of Taguig–Pateros's 1st district, filed one House Bill each in the 15th and 16th Congresses, respectively, that seek the conversion of Pateros into a city with its own legislative district. However, both bills ended up pending at the committee level.[16][17]

Delineation map showing territories claimed by Pateros.

The municipal government of Pateros claims that its original land area was not its present land area of 2.10 km² (0.81 sq mi) but 1,040 hectares (10.4 km²) including Fort Bonifacio, particularly the Embo barangays Comembo, Pembo, East Rembo, West Rembo, Cembo, South Cembo, Pitogo, and Rizal which are now part of the city of Makati and Bonifacio Global City (known as Post Proper Northside and Post Proper Southside by Makati, and Mamancat, Masilang,[22] San Nicolas,[23] and Malapadnabato,[24] former parts of Pateros) which was made part of Taguig, based on documents and official maps obtained by former Pateros Councilor Dominador Rosales from 30 libraries and offices including USA Library of Congress and USA Archives. One of those maps was the 1968 Land Classification Map of the Bureau of Land.[25] Also included in their claim are the present-day barangays Buting, San Joaquin, and Kalawaan in Pasig.

Pateros' decrease in territory was accounted to a cadastral mapping in Metro Manila conducted in 1978. Pateros Mayor Nestor Ponce challenged the map through an objection letter dated June 23, 1978.[26] But in January 1986, then President Ferdinand Marcos issued Proclamation No. 2475 which stated that Fort Bonifacio is situated in Makati and it is open for disposition.[27] Because of that, a boundary dispute arose which moved Pateros to request a dialogue about that with then Municipal Council of Makati in 1990. Pateros also filed a complaint against Makati at the Makati Regional Trial Court in 1996 but the trial court dismissed the case for lack of jurisdiction. The case was brought to the Court of Appeals in 2003 but the case was also denied. The same case was also elevated to the Supreme Court in 2009 but it was denied again.[25][28]

Almost two decades later, the Supreme Court on June 16, 2009, per Antonio Eduardo B. Nachura denied Pateros' petition against Makati but ruled out that the boundary dispute should be settled amicably by their respective legislative bodies based on Section 118(d) of the Local Government Code.[29] Pursuant to the decision, Pateros invited Makati to a council-to-council dialogue. This happened on October 8, 2009. Four meetings were held and at the fourth dialogue on November 23, 2009, a joint resolution was made stating that Makati is requesting a tripartite conference between Pateros, Taguig and Makati.[30]

Despite the resolution of the dispute between Taguig and Makati in favor of the former by the Supreme Court in 2023, the high court has allowed Pateros to pursue its claims.[31]
