Prague, Nov 5 (CTK) - Communism is still a significant phenomenon and people may tend to see hope in it mainly in the times of a crisis, Jiri Kocian, deputy head of the Czech Science Academy's Institute of Contemporary History, told CTK at the end of a three-day conference on communism Saturday.

The conference held in Prague focused on the 90-year history of Czech and Slovak communism.

Many people are remembering the totalitarian regime as the period of social certainties, Kocian said.

He stressed that new knowledge on communism must become a part of school textbooks and the threat of communism as the period of repressions and persecution must be constantly reminded.
