The eruption of the Krakatoa volcano in 1883 is considered one of the most violent and deadly in history. In August 1883, this volcanic activity ended with the lives of approximately 36,000 people. One of the ways in which this activity directly affected the population of the region was by the blasts of the volcano and the consequent thermal injuries. Another way in which the population was affected was by the tsunamis generated by the collapse of the volcano. Finally, the eruption had an impact on the global climate, generating temperature drops throughout the world.

These protests would include sit-ins and marches, which would get them jailed. Dr. King encouraged the nonviolent protest in order for the jails to overflow.
