History
The Cordillera's peoples — Ifugao, Bontoc, Kankanaey, Ibaloi, Kalinga and others — farmed their valleys in terraces long before Europeans arrived; how old the terraces are is still debated, with some researchers arguing that many were built within the last few centuries. Spain never fully controlled the mountains, and the highlanders kept their own law, religion and feasting traditions. The lowlands were another story. Juan de Salcedo explored the Ilocos coast in 1572, and Vigan became the seat of Spanish power in the north, growing rich on trade and, from 1782, on the tobacco monopoly that forced farmers in Ilocos and the Cagayan valley to grow the crop for the state.
The Ilocos produced repeated revolts: Diego Silang rose in 1762–63 and, after his assassination, his widow Gabriela Silang fought on; the Basi Revolt of 1807 broke out when Spain restricted the local sugarcane wine. Under American rule the Cordillera was opened by roads and missions, and Baguio was laid out from 1904, partly to a plan by the architect Daniel Burnham, as the colonial summer capital.
In the Second World War General Yamashita made his last stand in the Cordillera, holding out until he surrendered at Kiangan on 2 September 1945. The region later gave the country its most famous Ilocano, Ferdinand Marcos, born in Sarrat, Ilocos Norte, and during his rule Cordillera and Kalinga communities fought the Chico River dam project, which was shelved in the 1980s. The 1990 Luzon earthquake devastated Baguio. Batanes, the islands closest to Taiwan, has taken on new strategic weight in recent years.
