Gandhi led Congress celebrated 26 January 1930 as India's Independence Day in Lahore. This day was commemorated by almost every other Indian organisation. Gandhi then launched a new Satyagraha against the tax on salt in March 1930.
Gandhi joined the Indian National Congress and was introduced to Indian issues, politics and the Indian people primarily by Gokhale (the key leader of the Congress Party). Gandhi took leadership of the Congress in 1920 and began escalating demands until on 26 January 1930 the Indian National Congress declared the independence of India. The British did not recognize the declaration but negotiations ensued, with the Congress taking a role in provincial government in the late 1930s.
Gandhi sent an ultimatum in the form of a polite letter to the viceroy of India, Lord Irwin, on 2 March. A young left wing British Quaker by the name of Reg Reynolds delivered the letter. Gandhi condemned British rule in the letter, describing it as "a curse" that "has impoverished the dumb millions by a system of progressive exploitation and by a ruinously expensive military and civil administration... It has reduced us politically to serfdom." Gandhi also mentioned in the letter that the viceroy received a salary "over five thousand times India's average income. British violence, Gandhi promised, was going to be defeated by Indian non-violence.
This (Gandhi's letter to the viceroy of India) was highlighted by the famous Salt March to Dandi from 12 March to 6 April, where, together with 78 volunteers, he marched 388 kilometres (241 mi) from Ahmedabad to Dandi, Gujarat to make salt himself, with the declared intention of breaking the salt laws. Thousands of Indians joined him on this march to the sea. The march took 25 days to cover 240 miles with Gandhi speaking to often huge crowds along the way.
Dow reaches a secondary closing peak (i.e., bear market rally) of 294.07, followed by a long stagnation until a severe decline began in April 1931. This peak matches early-1929 levels, but is 30% below the September 1929 peak.
The Bank for International Settlements (BIS) became an object of scrutiny when the Norwegian delegation put forth evidence that the BIS was involved in war crimes. The BIS, formed in 1930, was originally primarily intended to facilitate settling financial obligations arising from the peace treaties that concluded the First World War.
Smoot-Hawley Tariff Act passed, placing more stress on the weakening global economy, primarily through the collapse in trade of agricultural products, which strained banks that had lent heavily to farmers. Further decreases in trade of manufactured products led to layoffs and reduced corporate profits, weakening the economy. General consensus among economists is that the Smoot-Hawley Act did not cause the Depression, but did worsen it and stunted recovery efforts after 1933. Exports declined from $5.2 billion in 1929 to just $1.7 billion in 1933.
In 1930, FIFA made the decision to stage their own international tournament. The 1932 Summer Olympics, held in Los Angeles, did not plan to include football as part of the programme due to the low popularity of the sport in the United States. FIFA and the IOC also disagreed over the status of amateur players, and so football was dropped from the Games. FIFA president Jules Rimet thus set about organizing the inaugural World Cup tournament.
On July 26, 1930, João Pessoa was assassinated by João Dantas in Recife for political and personal reasons. This became the flashpoint for armed mobilization. João Dantas and his brother-in-law & accomplice, Moreira Caldas, were found beheaded in their cell at the House of Detention (today the House of Culture) in 1930.
Margaret was born on 21 August 1930 at Glamis Castle in Scotland, her mother's ancestral home, and was affectionately known as Margot within the royal family. She was delivered by Sir Henry Simson, the royal obstetrician. The Home Secretary, J. R. Clynes, was present to verify the birth. The registration of her birth was delayed for several days to avoid her being numbered 13 in the parish register.
The elections of September 1930 resulted in the break-up of a grand coalition and its replacement with a minority cabinet. Its leader, chancellor Heinrich Brüning of the Center Party, governed through emergency decrees from President Paul von Hindenburg. Governance by decree became the new norm and paved the way for authoritarian forms of government. The NSDAP rose from obscurity to win 18.3 per cent of the vote and 107 parliamentary seats in the 1930 election, becoming the second-largest party in parliament.
On October 12 and 13, the Battle of Quatiguá took place (possibly the biggest fight of the revolution), although it has been little studied. Quatiguá is located to the east of Jaguariaíva, near the border between São Paulo state and Paraná.
Bank of Italy was renamed on November 3, 1930, to Bank of America National Trust and Savings Association, which was the only such designated bank in the United States at that time. Giannini and Monnette headed the resulting company, serving as co-chairs.
Moving on to ophthalmia neonatorum, a gonococcal infection in infants, Cecil George Paine achieved the first recorded cure with penicillin, on November 25, 1930. He then cured four additional patients (one adult and three infants) of eye infections, and failed to cure a fifth.
