This was the nonviolent protest led by Mohandas Gandhi in 1930 in which millions of Indians attempted to break the British monopoly of an important product used by billions of people around the world.

That protest was named the Salt March. Since the 19th century, Britain had kept a monopoly of the salt trade, prohibiting Indians to produce and trade with it and forcing Indians to buy it a high price from British merchants. It affected everybody, rich and poor , Hindu and Muslim alike.Though many of his collaborators did not see the sense of a protest related to the salt business, Mahatma Gandhi saw the salt trade as an example of how everyday life for Indians could be so oppresive because of British colonial interests. On March 12, 1930, Gandhi and his supporters started their march from Ahmedabad to Dandi in the Arabian Sea.

explanation:

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
