7 September History: Uncle Sam, Brazil Independence and The Blitz

7 September History: September 7 holds significance in both Indian and world history, with the date associated with major political developments, wartime events, international observances and notable personalities. From the first known printed use of the name “Uncle Sam” in the United States in 1813 to Brazil’s declaration of independence in 1822 and the beginning of Germany’s Blitz against London in 1940, several events have shaped the historical importance of the day.

The date is also observed as the International Day of Clean Air for Blue Skies and the International Day of Police Cooperation, both recognised by the United Nations.

1813: ‘Uncle Sam’ enters American history

One of the most widely remembered events linked to September 7 occurred in 1813, when the name “Uncle Sam” was used in connection with the United States. The expression became associated with the US government and later evolved into a familiar national symbol of the country.

The date is linked to an item published in the Troy Post during the War of 1812. The popular explanation connects the nickname with Samuel Wilson, a meat supplier from Troy, New York, who supplied beef to the US Army.

1822: Brazil declares independence

September 7 is celebrated every year as Brazil’s Independence Day. On this day in 1822, Prince Pedro declared Brazil’s independence from Portugal.

The event marked a decisive break with Portuguese colonial rule and laid the foundation for the independent Brazilian state. Brazil continues to observe September 7 as its national Independence Day.

1931: Second Round Table Conference

In 1931, the second session of the Round Table Conference began in London on September 7. The conference was part of British efforts to discuss constitutional reforms and the political future of India.

The discussions took place during a crucial period of India’s freedom movement and involved representatives of different political and social interests.

1940: Germany begins The Blitz

September 7, 1940, marked the beginning of one of the most devastating phases of the Second World War for Britain. Nazi Germany launched a major bombing campaign against London, beginning what became known as The Blitz.

The bombing campaign continued for months and targeted British cities and industrial centres. According to historical records cited by the Associated Press, the wider campaign ultimately caused more than 40,000 civilian deaths in Britain.

1977: Panama Canal treaties signed

Another major international event took place on September 7, 1977, when US President Jimmy Carter signed the treaties concerning the future of the Panama Canal.

The agreements set the process for transferring control of the canal from the United States to Panama, making the date an important milestone in the modern political history of the region.

1998: Google’s founding date needs clarification

Some lists of September 7 historical events incorrectly mention Google’s establishment in 1998. However, Google’s own historical account says Google Inc. was incorporated on September 4, 1998.

The company also notes that it has traditionally celebrated its birthday on September 27. Therefore, Google’s founding should not be presented as a September 7 event without qualification.

Important days observed on September 7

September 7 is now associated with two UN-designated international observances. The International Day of Clean Air for Blue Skies focuses attention on air pollution, air quality and the need for coordinated action. The UN designated September 7 for this observance beginning in 2020.

The International Day of Police Cooperation is also observed on September 7. The UN General Assembly established the day in 2022, with the first observance taking place in 2023. The date was chosen because the International Criminal Police Commission, INTERPOL’s predecessor, was established on September 7, 1923.

September 7 in Indian history

The date also has connections with Indian history and public life. Historical references include the birth of Ela Bhatt, founder of the Self-Employed Women’s Association (SEWA), on September 7, 1933.

September 7 is also associated with the birth anniversary of Neerja Bhanot, the Indian flight attendant who was born in Chandigarh in 1963 and later became known for her bravery during the 1986 Pan Am Flight 73 hijacking.
