Before sugar, it was cattle ranching and the cutting and exporting of hardwoods that drove the region’s economy. But Cuban planters, fleeing war in their country, began to arrive in the southeast in the 1870s and established sugar mills with the Dominican government’s assistance (this migration also explains baseball’s popularity and importance in the region). Rail lines were built and La Romana and San Pedro de Macorís, formerly sleepy backwaters, began to prosper as busy ports almost immediately as world sugar prices soared. Hundreds of families from the interior migrated to the area in search of jobs. In 1920, after peasants were dispossessed of their land during the US occupation, many fought a guerilla war against the marines in the area around Hato Mayor and El Seibo. Until the 1960s, the economy in the southeast was still strictly driven by sugar despite fluctuations in the world market and agriculture in general. However, when the US company Gulf & Western Industries bought La Romana’s sugar mill, invested heavily in the cattle and cement industries and, perhaps most importantly, built the Casa de Campo resort, tourism became the financial engine of the southeast, and remains so to this day.
