Why were both ideas and institutions necessary in the global influence of the Russian Revolution?

Correct answer: Ideas inspired people and institutions gave those ideas an organised form

The governing concept is the relationship between ideology and organisation. Revolutionary ideas such as equality, workers’ power and opposition to exploitation could inspire people in many countries, but ideas alone did not automatically create lasting movements. Institutions—including parties, newspapers, study groups, trade unions and international networks—helped communicate principles, train activists, coordinate campaigns and turn general sympathy into organised action. Therefore, option A is correct because ideas supplied purpose while institutions supplied continuity and practical structure. Option B denies the clear intellectual influence of socialism. Option C confuses revolutionary institutions with the Tsar’s personal property, and option D contradicts the socialist character of the ideas and organisations involved.
