I want to know the answer to the following question:
What took place frequently until 1953?
All the background I'm provided with is that "While the National Revolutionary Movement government begun in 1952 discouraged self-identification as indigenous (reclassifying rural people as campesinos, or peasants), renewed ethnic and class militancy re-emerged in the Katarista movement beginning in the 1970s.". Is that enough to answer the question?
Answer: no
