The district was represented by a total of only three representatives throughout its brief existence. It was abolished in 1919 following the passage of Legislative Act No. 2683 which created the province of Abra in 1917. As a result, Santa remained in Ilocos Sur and was redistricted to the 2nd district, while the other towns became part of Abra and were redistricted to its new at-large district.[4] The district was last represented by Eustaquio Purugganan of the Nacionalista Party (NP) who was also elected as the first representative of Abra's at-large congressional district following its dissolution.[1]
