South Koreans can be as proud of their country’s emergence from dictatorship into a vibrant democracy as they are of the rags-to-riches development that made their country a global industrial powerhouse. So it is alarming that President Park Geun-hye appears intent on backtracking on the democratic freedoms that have made South Korea as different from North Korea’s puppet regime as day is from night.

Last weekend, tens of thousands of South Koreans took to the streets to protest two repressive government initiatives. One would replace the independently selected history textbooks now available to South Korea’s educators with government-issued textbooks. The other would change labor laws to make it easier for South Korea’s family-controlled business conglomerates to fire workers.

Ms. Park is also attempting to control criticism and dissent on social media and the Internet. On Saturday, Lee Sir-goo, the co-chief executive of South Korea’s most popular messaging app, stepped down. He is facing criminal charges for failing to prevent teenagers from posting lewd photos, but critics contend the real goal is to punish him for resisting government surveillance efforts and refusing to curb users’ opinions critical of the government.

Ms. Park is the daughter of Gen. Park Chung-hee, who was an Imperial Japanese officer in the colonial era and South Korea’s military dictator from 1961 to 1979. Rehabilitating her father’s image appears to be one motivation for making sure South Korea’s students learn a whitewashed version of their country’s history — especially the period when democratic freedoms were seen as an impediment to industrialization.
