30 September - Aurangzeb acquired the famous Golconda fort near Hyderabad

 

On 30 September 1687, the Mughal Emperor Aurangzeb successfully acquired the famous Golconda Fort, near Hyderabad, after a long siege. This marked the end of the Qutb Shahi dynasty and the annexation of the Golconda Sultanate into the Mughal Empire.

Background:

• The Golconda Sultanate, ruled by Sultan Abul Hasan Tana Shah, was one of the five Deccan Sultanates. Golconda was known for its wealth, particularly its diamond mines, including the famous Koh-i-Noor and Hope Diamond.
• Aurangzeb, aiming to consolidate Mughal control over southern India, had long sought to conquer Golconda, which had resisted Mughal expansion.

Siege of Golconda:

• Aurangzeb laid siege to the Golconda Fort in early 1687. The fort was well-fortified and known for its almost impregnable walls. Tana Shah and his forces offered strong resistance, holding out against the Mughals for several months.
• The siege dragged on, with the Mughal army failing to breach the walls through direct assaults or bombardment.

Treachery of General Panni:

• Aurangzeb’s victory was eventually secured not through military might but by treachery. One of Tana Shah’s trusted generals, Abdullah Khan Panni, betrayed him by secretly allowing Mughal forces to enter the fort.
• On 30 September 1687, Mughal forces, led by Aurangzeb’s generals, entered Golconda Fort and captured Tana Shah, who was later imprisoned for life in Daulatabad Fort. This betrayal was a crucial turning point, leading to the fall of the fort and the Sultanate.

Significance:

• The fall of Golconda marked the end of the Qutb Shahi dynasty and the annexation of one of the wealthiest kingdoms in southern India into the Mughal Empire.
• The conquest also gave Aurangzeb control over the legendary Golconda diamond mines, which added immense wealth to the Mughal treasury.
• Aurangzeb’s victory at Golconda was part of his broader Deccan campaigns, which expanded Mughal rule in southern India but also strained the empire’s resources and led to eventual decline.

30 September - Johann Sebastiani birth anniversary

 

Johann Sebastiani (30 September 1622 – 1683) was a German baroque composer. Sebastiani was born in Weimar. He became Kantor at Königsberg cathedral in 1661, and court Kapellmeister from 1663 to 1679. He died in Königsberg. His works include sacred and occasional pieces and songs; the most famous is his St Matthew Passion (before 1663, performed again 1672). He is the first composer to introduce chorale into oratorio passion. Within the St Matthew Passion, Sebastiani includes eight different chorale melodies and introduces thirteen chorale verses.This work is a development from the style of Heinrich Schütz which includes recitatives and arias but avoids a dramatic operatic idiom, and marks an intermediate position between Schütz and Bach such as those of Johann Theile and Johann Valentin Meder.Two violins accompany Christ, who is a bass; three viols accompany Evangelist, who is a tenor, Judas, who is an alto, and the other characters. In 1672 Sebastiani got married and from that point until the end of his life he was concerned primarily with the publication of his works. In 1672, he published a collection entitled Erster Theil Der Parnaß-Blumen, Oder Geist- und Weltliche Lieder

30 September - Stephen Smith, an American engineer and inventor, made history by launching his first mail rocket

 

On September 30, 1934, Stephen Smith, an American engineer and inventor, made history by launching his first mail rocket. This event took place in Greenwood Lake, New York, and it marked an experimental attempt to deliver mail using a small rocket.

Smith's mail rocket, powered by solid fuel, was designed to carry a small payload of mail from one location to another. In this case, he launched it from one side of Greenwood Lake to the other, covering a distance of about one mile. The rocket successfully carried a batch of mail across the lake, making it one of the earliest known instances of mail delivery by rocket.

While Smith's experiment was a notable achievement and garnered attention at the time, it did not lead to widespread adoption of rocket mail as a practical means of mail delivery. The limitations and safety concerns associated with rocket propulsion and the traditional postal system's reliability ultimately limited the development of rocket mail for routine mail delivery.

Nonetheless, Stephen Smith's pioneering effort in 1934 remains a part of the history of early rocketry and mail transportation experiments.

27 September - Vithalbhai Patel birth anniversary

 

Vithalbhai Patel, elder brother of Sardar Vallabhbhai Patel was one of the stalwarts of the nationalist movement in the ‘twenties’ and ‘thirties’. Jawaharlal Nehru in his autobiography, wrote that he had been “a great and indomitable fighter for India’s freedom”. He joined the Congress in 1915. Later he became a Swaraj Party leader and a close associate of Motilal Nehru and C.R. Das. A brilliant parliamentarian, he was elected as President of the Central Assembly in 1925. Master of parliamentary rules and procedures he evoked praise from all quarters for editing the proceedings of the house. Yet, as Nehru has noted, he had become a thorn in the tender side of the government on account of his independence (of them) and attempts were made to clip his wings”. Vithalbhai Patel was born on 27 September 1873 in Karmasad in Gujarat. After an early education at Karmasad and Nadiad, Vithalbhai went to Bombay and qualified for district leadership. In a few years, he became a well-known lawyer with considerable practice. His younger brother, Vallabhbhai followed in his footsteps. After his return from England in 1908, as a barrister, Vithalbhai practiced in Bombay. Two years later after he lost his wife, he devoted himself entirely to public affairs. He was President of the Bombay Corporation and later he was elected to the Bombay Legislative Council as a representative of local self-governing bodies. Elected to the Central Assembly in New Delhi in 1915 he was very actively engaged in the political affairs of the day. In 1918, he was the Chairman of the Reception Committee for the Congress session held in Bombay. The next year he was representing the Congress in a delegation sent to England to represent its views to the Joint Parliamentary Committee on the Govt. of India Act. During the following year also he again went to England to plead India’s case. When Gandhiji started the non-cooperation movement Vithalbhai resigned his Assembly seat. Later in 1922, when differences arose on the issue of Council entry Vithalbhai along with C.R. Das and Motilal Nehru formed the Swaraj Party. This Party won 45 seats in the 1923 elections. Two years later he became the President of the Central Assembly. In 1930, when the Congress boycotted the legislatures, Vithalbhai resigned. The same year he was arrested along with other members of the Working Committee. Due to ill health, which dogged him from then on, he was released before the end of his term. In 1932 he was once again arrested, but due to illness, was allowed to go to Vienna for treatment. But illness did not prevent him from proceeding on a strenuous lecture tour of the United States. On his return to Vienna, he met Netaji Subhas Chandra Bose, who was then living there. Vithalbhai died on 22 October 1933 in Geneva, where he had gone to plead India’s case at the League of Nations. Jawaharlal Nehru has paid a moving tribute to Vithalbhai Patel which cannot be bettered. “His passing away was a painful event and the thought of our veteran leaders leaving us in the way, one after another, in the midst of our struggle was extraordinarily depressing”. Many tributes were paid to Vithalbhai and most of these laid stress on his ability as a Parliamentarian and his success as President of the Assembly. Vithalbhai was something much more than that – he had been a great and indomitable fighter for India’s freedom.

27 September - Albert Einstein's paper "Does the Inertia of a Body Depend Upon Its Energy Content?", introducing the equation E=mc² in 1905

 

The physics journal "Annalen der Physik" published Albert Einstein's groundbreaking paper titled "Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?" in 1905. The paper is more commonly known by its English translation: "Does the Inertia of a Body Depend Upon Its Energy Content?" In this paper, Albert Einstein introduced the famous equation E=mc², which is one of the most iconic equations in the field of physics.

The equation E=mc² expresses the equivalence of mass (m) and energy (E), with the constant of proportionality being the speed of light squared (c²). This equation fundamentally changed our understanding of the relationship between matter and energy, and it has had profound implications in various branches of physics, including nuclear physics and the development of atomic energy.

Einstein's work in this paper laid the foundation for the theory of special relativity, which revolutionized our understanding of space, time, and motion. It had a significant impact on the development of modern physics and led to many important discoveries and technological advancements in the 20th century.

 

27 September - The Tripartite Pact

 

The Tripartite Pact, also known as the Berlin Pact, was a military alliance signed on September 27, 1940, during World War II. It was an agreement between Nazi Germany, Fascist Italy, and Imperial Japan. The pact aimed to establish a mutual defense alliance among these three major Axis powers and outlined their collective goals and strategies in the war.

Key provisions of the Tripartite Pact included:

1. Mutual Assistance: The signatory countries pledged to support each other in case of attack by a country not already involved in the war (i.e., the Allied Powers, including the United States and the United Kingdom).

2. No Separate Peace: The signatories agreed not to make a separate peace with the Allied Powers, ensuring that they would continue fighting together until a mutually acceptable outcome was achieved.

3. Coordination: The pact aimed to coordinate the military and economic efforts of Germany, Italy, and Japan in pursuit of their shared objectives.

4. Cultural Exchange: There was a provision for cultural and economic exchange between the signatory nations, although the military aspects of the alliance were the primary focus.

The signing of the Tripartite Pact further solidified the Axis Powers' alliance during World War II. However, it also had significant consequences, particularly regarding the involvement of the United States in the war. Following the signing of the pact, the U.S. became more inclined to provide support to the Allied Powers, eventually leading to its entry into the conflict after the attack on Pearl Harbor in December 1941.

The Tripartite Pact played a role in shaping the dynamics of World War II and the alliances between the major powers during the war. As the war progressed, the Axis Powers faced increasing resistance from the Allied Powers, and the pact did not prevent their eventual defeat.

26 September - Day of the National Flag (Ecuador)

 

Day of the National Flag in Ecuador, celebrated on 26 September is a national holiday that honors the country’s flag and its significance in Ecuadorian history and identity. The flag of Ecuador, consisting of three horizontal bands of yellow (top, twice as wide), blue, and red, symbolizes the nation's natural wealth, the sky and ocean, and the blood shed for independence, respectively.

The flag is closely tied to the legacy of Gran Colombia, the short-lived republic of which Ecuador was a part, alongside Colombia, Venezuela, and Panama. Ecuador adopted its current design officially on 26 September 1860, when President Gabriel García Moreno decreed it, reinstating the tricolor flag originally used by Gran Colombia.

On this day, Ecuadorians celebrate with flag-raising ceremonies, parades, and civic events that emphasize patriotism, unity, and respect for the national symbol. Schools, government institutions, and public spaces often participate in commemorations that reflect the importance of the flag in Ecuador’s history and national pride.

26 Spetember - World Cassowary Day

 

World Cassowary Day is celebrated annually on September 26 to raise awareness about the endangered cassowary, a large flightless bird native to the tropical rainforests of New Guinea, nearby islands, and northern Australia. The day highlights the importance of protecting this unique species and its habitat, as cassowaries play a vital role in their ecosystems by dispersing seeds from the fruits they eat.

The Southern Cassowary, in particular, is considered a keystone species due to its ecological role. Unfortunately, the cassowary population is under threat from habitat destruction, vehicle collisions, and human activity.

Events and activities on World Cassowary Day focus on educating people about conservation efforts, protecting cassowary habitats, and encouraging responsible interaction with wildlife.

26 September - Petrov Day

 

Petrov Day is observed annually on September 26 to commemorate a critical moment in history when a single individual, Soviet Lieutenant Colonel Stanislav Petrov, prevented a potential nuclear war between the United States and the Soviet Union during the Cold War.

On September 26, 1983, amidst heightened tensions between the superpowers, Soviet early-warning systems detected what appeared to be a missile launch from the United States. The system indicated that five U.S. missiles were headed towards the Soviet Union. Protocol at the time would have required Petrov, who was the duty officer at the command center, to report the alarm up the chain of command, potentially triggering a retaliatory nuclear strike.

However, Petrov made a calm and critical decision: he chose to dismiss the alarm as a false report, reasoning that a real attack would likely involve hundreds of missiles, not just five. His intuition and refusal to follow protocol averted what could have been a catastrophic nuclear conflict. It was later confirmed that the alert was a malfunction in the Soviet satellite system, and Petrov's judgment had saved the world from disaster.

Petrov Day is celebrated as a reminder of the importance of peace, rational thinking, and the weight of individual responsibility in preventing global crises. It highlights how a single person’s decision, guided by reason and caution, can have profound effects on humanity’s survival.

26 September - Revolution Day in Yemen

 

Revolution Day in Yemen, celebrated on 26 September commemorates the Yemeni Revolution of 1962, which marked the end of the centuries-old monarchy and the establishment of the Yemen Arab Republic (North Yemen).
