importance of communist parties is widely accepted, their activities and functions have been interpreted in different ways. One approach, sometimes known as the totalitarian school of communist studies, has implicitly treated all communist parties as the same types of organizations. Scholars such as Zbigniew Brzezinski and Francois Furet have relied upon conceptions of the party emphasizing centralized control, a top-down hierarchical structure, ideological rigidity, and strict party discipline. In contrast, other studies have emphasized the differences among communist parties. Multi-party studies, such as those by Robert C. Tucker and A. James McAdams, have emphasized the differences in both these parties' organizational structure and their use of Marxist and Leninist ideas to justify their policies. Another important question is why communist parties were able to rule for as long as they did. Some scholars have depicted these parties as fatally flawed from their inception and argue they only remained in power because their leaders were willing to use their monopoly of power to crush all forms of opposition. In contrast, other studies have emphasized these parties’ ability to adapt their policies to changing times and circumstances.
