About

Proceeding southward (or in alphabetical order, or upriver) through Region II we come to the Province of Isabela, created in 1856 and named for Isabela II, then the Queen of Spain. Isabela is the biggest (10,665 sq.km.) and most populous (1,277,000) province in the Cagayan Valley, and comprises one city (Santiago, for which I have no flag) and thirty-six towns, of which Ilagan is the capital. The Cagayan River runs through the central plains, which are separated from the coast by the Sierra Madre (now often called the Sierra Mountains [apologies to our Spanish-speaking friends]).

About half the land is forested, and the government looks to expand the existing trade in furniture, rattan products, and other forest products. The bulk of the economy is agricultural. Tobacco dominated in the eighteenth and nineteenth centuries. Imposition of a government tobacco monopoly in 1782 led to rebellion and the partial depopulation of many towns. Tobacco is still grown, but so too are rice, bananas, maize, coconuts, and vegetables. The coast is sparsely inhabited, though surfers come to play, and the government is building an airport and seaport on the coast to encourage development. The forests and caves of the wild east are still largely unexplored.
