Legislative districts of Isabela

{{Short description|Legislative district of the Philippines}} {{Politics of the Philippines}} The '''legislative districts of Isabela''' are the representations of the [[Provinces of the Philippines|province]] of [[Isabela (province)|Isabela]] and the [[Cities of the Philippines#Independent cities|independent component city]] of [[Santiago, Isabela|Santiago]] in the [[List of legislatures of the Philippines|various national legislatures]] of the [[Philippines]]. The province and the city are currently represented in the [[House of Representatives of the Philippines|lower house]] of the [[Congress of the Philippines]] through their [[#1st District|first]], [[#2nd District|second]], [[#3rd District|third]], [[#4th District|fourth]], [[#5th District|fifth]], and [[#6th District|sixth]] congressional districts.

== History == The province was represented as a lone [[House of Representatives of the Philippines#District representation|legislative district]] until 1972. It was part of the representation of [[Interim Batasang Pambansa|Region II]] from 1978 to 1984, and from 1984 to 1986, it elected 3 assemblymen at-large. In 1986, it was redistricted into four [[House of Representatives of the Philippines#District representation|legislative districts]].

On September 27, 2018, [[President of the Philippines|President]] [[Rodrigo Duterte]] signed Republic Act No. 11080,<ref>{{Cite web| title=An act reapportioning the province of Isabela into six (6) legislative districts | url=http://www.officialgazette.gov.ph/downloads/2018/09sep/20180927-RA-11080-RRD.pdf | archive-url=https://web.archive.org/web/20180928121613/http://www.officialgazette.gov.ph/downloads/2018/09sep/20180927-RA-11080-RRD.pdf | archive-date=2018-09-28}}</ref> increasing the legislative districts from four to six and reapportioned the district assignments of cities and municipalities.<ref>{{cite web|url=https://newsinfo.inquirer.net/1036988/duterte-creates-two-new-legislative-districts-in-isabela|title=Duterte creates two new legislative districts in Isabela|first=Darryl John|last=Esguerra|website=newsinfo.inquirer.net|date=27 September 2018}}</ref>

== Current districts == The province was last redistricted on September 27, 2018, where the fifth and sixth districts were apportioned. All six representatives are part of the majority bloc in the [[20th Congress of the Philippines|20th Congress]].
