On March 12, 1930, Indian independence leader Mohandas Gandhi begins a defiant march to the sea in protest of the British monopoly on salt, his boldest act of civil disobedience yet against British rule in India.
Britain's Salt Acts prohibited Indians from collecting or selling salt, a staple in the Indian diet. Citizens were forced to buy the vital mineral from the British, who, in addition to exercising a monopoly over the manufacture and sale of salt, also exerted a heavy salt tax.
Although India's poor suffered most under the tax, Indians required salt. Defying the Salt Acts, Gandhi reasoned, would be an ingeniously simple way for many Indians to break a British law nonviolently.
On this day in history, Nazi leader Adolf Hitler violates the Treaty of Versailles and the Locarno Pact by sending German military forces into the Rhineland, a demilitarized zone along the Rhine River in western Germany.
In 1935, Hitler unilaterally canceled the military clauses of the treaty and in March 1936 denounced the Locarno Pact and began remilitarizing of the Rhineland. Two years later, Nazi Germany burst out of its territories, absorbing Austria and portions of Czechoslovakia.
In 1939, Hitler invaded Poland, leading to the outbreak of World War II in Europe.
