Crisis of the Colonial System of Imperialism, crisis of economic and political domination of the imperialist powers in the colonial and dependent countries, one of the characteristic features of the new stage of general crisis of capitalism. The essence of the crisis of the colonial system of imperialism is the fact that the imperialists are no longer in a position to dominate the colonies as they did of old, nor are they able to retain their dominance using their former methods of violence, as the people of the colonial and dependent countries refuse to live in the old way any longer and start fighting for their liberation. The Great October Socialist Revolution opened the epoch of victorious national liberation revolutions in the colonial and dependent countries, and brought the peoples of the colonial world into the mainstream of the world revolutionary movement. It was a catalyst for the revolutions in Iran and Afghanistan, the popular uprising in Syria, the national liberation war against French and Spanish imperialism in Morocco, the war against American imperialism in Mexico and Nicaragua. National liberation struggle flared up in the largest Asian colonies and semicolonies, including China, India, Indonesia and Southeast Asia. The October Revolution inspired the peoples of the colonial and dependent countries to struggle against the imperialist yoke, awakened class and national consciousness, and pointed the way to socialism. Marxist-Leninist parties emerged and entrenched themselves in these countries. These parties avail themselves of the experience of the CPSU and enjoy the support of the Soviet Union. The crisis of the colonial system and the upsurge of the national liberation movement in the colonial and dependent countries after the Great October Socialist Revolution testify to the fact that the era of untroubled imperialist exploitation of the colonial peoples has irreversibly become a thing of the past; it has been replaced by the epoch of 78 liberation revolutions, which swept the formerly oppressed peoples and brought them into the world revolutionary movement. A new stage in the crisis of the colonial system of imperialism began during World War II and especially after it. This process was logically crowned by the collapse of the colonial system of imperialism in the third stage of the general crisis of capitalism.
