History and government
The word Langiden originated from an Ilocano term “langi” meaning the outgrowth of a plant as in the development of a bamboo shoot. Langiden was considered a shoot which grew from an old small village to a new town. To add beauty and color, the word “den” was added to the word “langi” forming the word langiden.
Langiden is one of the oldest inhabited localities of Abra. Its natives originated from the second wave of malay immigrants who came to the philippines and and landed on the shores of Northern Luzon specially Ilocos Sur where the Abra River emptied its overflow. With the coming of the Spaniards, many Malay immigrants resited their conversion to Christianity. They were then driven upstream of the Abra River into the hinterlands of Abra by the Spaniards calling them Itnegs or Tinguians. Most of the Tinguians settled on the eastern bank of the Abra River at sitio Calawag now called Nagbabayan. Some of them however, went further upstream giving birth to other settlements with some settling on what is now Langiden. Some of the early settlements which grew as Barangays forming Langiden were: Baac, Dalayap, Quillat, Malapaao and Poblacion.
At present, Langiden has 6 barangays namely: Poblacion, Dalayap, Mabungtot, Malapaao, Baac, Quillat. Among the barangay only Mabungtot has a legend. According to old folks, Mabungtot derive from the word Nabungtot an Ilocano term which means foul odor of a decaying animal. Then animal in the early days drowned by flood usually landed in Mabungtot and emmited and emitted a foul odor. Because of the foul smell, the place was then called Mabungtot.
The official flower of the town is orchid due to its unique beauty and fragrance, a characteristic the people associate with Langiden, being the oldest and widest among the municipalities of Abra.
