Brazil Independence Day
Brazil Independence Day, or Sete de Setembro (7th of September), is celebrated annually on September 7 to commemorate the nation's declaration of independence from the United Kingdom of Portugal, Brazil, and the Algarves in 1822.
History
· The path to independence began after French forces invaded Portugal in 1807 during the Napoleonic Wars. This prompted the Portuguese royal family to flee to their colony in Brazil.
· While in Brazil, the Portuguese Prince Regent, Dom João VI, elevated Brazil's status from a colony to an equal kingdom within the United Kingdom of Portugal, Brazil, and the Algarves.
· After
the French were defeated, the royal family returned to Lisbon. However, Prince
Dom Pedro was left as regent of Brazil. When the Portuguese parliament later
demanded that Brazil revert to its former colonial status, Dom Pedro refused.
On January 9, 1822, he declared his intention to stay in the country.
· On September 7, 1822, Princess Maria Leopoldina sent a letter advising Dom Pedro to declare independence. Dom Pedro then famously proclaimed "Independência ou Morte!" ("Independence or Death!") near the Ipiranga River in São Paulo.
· He was crowned Emperor Dom Pedro I of Brazil, and Portugal officially recognized Brazil's independence in 1825.
Celebrations
· Military parades: Grand civil-military parades led by the president are held in Brasília, the capital. They feature military vehicles, armed forces, and public security forces. Similar parades occur in state capitals and other cities.
· Cultural events: Throughout the country, celebrations feature music, folk performances, and cultural activities. These vary by region, with some cities, like Salvador, incorporating Afro-Brazilian traditions into their festivals.
· Patriotic displays: Brazilians show their national pride by flying the national flag from buildings and vehicles, and wearing clothing in the national colours of green, yellow, and blue.
· Festivals and fireworks: Major cities often host public concerts and end the day with spectacular fireworks displays. Informal street parties, or blocos, are also common.
· Traditional
food: Families and
friends gather for barbecues (churrasco) and other meals. They enjoy
traditional Brazilian foods like feijoada and pão de
queijo.

Sir Donald Bradman's Birth Anniversary
Sir Donald George Bradman, born on 27 August 1908, in Cootamundra, New South Wales, Australia, nicknamed "The Don", was an Australian international cricketer, widely acknowledged as the greatest batsman of all time. His cricketing successes have been claimed by Shane Warne, among others, to make Bradman the "greatest sportsperson" in history. Bradman's career Test batting average of 99.94 is considered by some to be the greatest achievement by any sportsman in any major sport.
The story that the young Bradman practiced alone with a cricket stump and a golf ball is part of Australian folklore. His meteoric rise from bush cricket to the Australian Test team took just over two years. Before his 22nd birthday, he had set many records for top-scoring, some of which still stand, and became Australia's sporting idol at the height of the Great Depression. This hero status grew and continued through the Second World War.
During a 20-year playing career, Bradman consistently scored at a level that made him, in the words of former Australia captain Bill Woodfull, "worth three batsmen to Australia". A controversial set of tactics, known as Bodyline, was specially devised by the England team to curb his scoring. As a captain and administrator, Bradman was committed to attacking, entertaining cricket; he drew spectators in record numbers. He hated the constant adulation, however, and it affected how he dealt with others. The focus of attention on Bradman's individual performances strained relationships with some teammates, administrators and journalists, who thought him aloof and wary. Following an enforced hiatus due to the Second World War, he made a dramatic comeback, captaining an Australian team known as "The Invincibles” on a record-breaking unbeaten tour of England.
A complex and highly driven man, not
given to close personal relationships, Bradman retained a pre-eminent position
in the game by acting as an administrator, selector and writer for three
decades following his retirement. Even after he became reclusive in his
declining years, Bradman's opinion was highly sought, and his status as a
national icon was still recognized. Almost fifty years after his retirement as
a Test player, in 1997, Prime Minister John Howard called him the
"greatest living Australian". Bradman's image has appeared on postage
stamps and coins, and a museum dedicated to his life was opened while he was
still living. On the centenary of his birth, 27 August 2008, the Royal
Australian Mint issued a $5 commemorative gold coin with Bradman's image. In
2009, he was inducted posthumously as an inaugural member into the ICC Cricket
Hall of Fame.

Saint Mother Teresa's Birth Anniversary
Mary Teresa Bojaxhiu, born Anjezë Gonxhe Bojaxhiu, on 26 August 1910, better known as Mother Teresa or Saint Mother Teresa, was an Albanian-Indian Catholic nun, founder of the Missionaries of Charity and is a Catholic saint. Born in Skopje, then part of the Ottoman Empire, she was raised in a devoutly Catholic family. At the age of 18, she moved to Ireland to join the Sisters of Loreto and later to India, where she lived most of her life and carried out her missionary work. On 4 September 2016, she was canonized by the Catholic Church as Saint Teresa of Calcutta. The anniversary of her death, 5 September, is now observed as her feast day.
In 1950, Mother Teresa established the Missionaries
of Charity, a religious congregation that was initially dedicated to serving
"the poorest of the poor" in the slums of Calcutta. Over the
decades, the congregation grew to operate in over 133 countries, as of 2012, with
more than 4,500 nuns managing homes for those dying from HIV/AIDS, leprosy,
and tuberculosis, as well as running soup kitchens, dispensaries, mobile
clinics, orphanages, and schools. Members of the order take vows of chastity,
poverty and obedience and also profess a fourth vow: to give
"wholehearted free service to the poorest of the poor."
Mother Teresa received several
honours, including the 1962 Ramon Magsaysay Peace Prize and the 1979 Nobel
Peace Prize. Her life and work have inspired books, documentaries, and films.
Her authorized biography, written by Navin Chawla, was published in 1992,
and on 6 September 2017, she was named a co-patron of the Roman Catholic
Archdiocese of Calcutta alongside St Francis Xavier. However, she also drew
criticism for the poor conditions and lack of medical care or pain relief in
her houses for the dying.

Vesuvius Day
August 24 is commemorated as Vesuvius Day, honouring the most famous eruption of Mount Vesuvius in 79 A.D., which destroyed the Roman cities of Pompeii and Herculaneum.
The historical date and its revision
· The traditional
date (August 24, 79 A.D.): For
centuries, this date was widely accepted based on a copy of a letter by Pliny
the Younger, an eyewitness to the event. Pliny wrote his account 20 years after
the disaster, and the date may have been corrupted over 1,400 years of
hand-copying.
· The revised date (October 24, 79 A.D.): In 2018, an inscription found on a wall in Pompeii dated to October 17th of 79 A.D. supported a theory that had been building since the 18th century. Other archaeological evidence, such as findings of autumnal fruits and victims wearing heavy clothing, also points to an autumn eruption.
Commemorating "Vesuvius Day"
Today, August 24 is still observed as "Vesuvius Day" by some as a tribute to the victims, though it's now widely acknowledged that the disaster occurred later in the year. Ways to observe the day include:
· Learning about volcanoes and the history of the eruption.
· Watching documentaries about Pompeii and Herculaneum.
· Creating a model volcano with children.
Visiting Mount Vesuvius today
For those
interested in exploring the site, tours and day trips are available from nearby
cities like Naples and Rome. Visitors can hike to the crater of the volcano and
explore the remarkably preserved ruins of Pompeii.

Madras Day
Chennai, the southernmost Indian metropolis, previously known as Madras, is commemorates its founding day today on August 22. Every year on Madras Day, the city comes together to celebrate its origins with joy and lots of festivities. Madras is not just the capital of Tamil Nadu but also a focal point of India's cinema, sports and cultural activities -- making it a true cosmopolitan city.
Madras Day History
The city and the origin of Madras Day stretch all the way back to August 22, 1639. It was on this day that the East India Company (EIC) bought Madrasapatnam from local monarchs. Local Nayak ruler, Damarla Venkatadri Nayaka agreed to the deal with EIC officers viz., Francis Day, his superior, Andrew Cogan, and Day's Dubash (translator), Beri Thimmappa.
It was on this small patch of land that Fort St George was built, which would lay the foundations of the British Empire in India.
After India gained independence in 1947, Madras continued as the capital city of the Madras State and present-day Tamil Nadu. The state was formally renamed as Tamil Nadu in 1969, and the capital city of Madras changed its name to Chennai in 1996.
Madras Day Origins
Madras Day was initiated by a group of enthusiastic individuals who wanted to celebrate the rich history of the city. The first celebration took place in 2004, and since then, it has grown into a big festival filled with events, exhibitions, talks, and performances. These activities highlight various aspects of the city's identity, from its architecture and cuisine to its arts and traditions.
The day holds immense significance for the residents of the
city as it allows them to connect with their history and learn about the city's
evolution. It's a time to remember the great leaders who contributed to its
development, as well as to acknowledge the cultural diversity that makes
Chennai unique.
