1. Income Tax Was Introduced in India – 1860

1860

Why July 24 Is Observed as Income Tax Day

On July 24, 1860, income tax was introduced for the first time in India by Sir James Wilson, who served as the Finance Member of the Viceroy’s Council. The measure was introduced to address the severe financial pressure faced by the colonial administration after the Revolt of 1857.

India observes July 24 as Income Tax Day, also called Aaykar Diwas. The first system of 1860 did not remain unchanged; later milestones included the Income-tax Act of 1922 and the Income-tax Act of 1961.

An important current update for students is that the Income-tax Act, 2025, as amended by the Finance Act, 2026, generally came into force on April 1, 2026. This makes the topic relevant to both history and current affairs.

1783

“El Libertador” and South American Independence

Simón Bolívar was born in Caracas on July 24, 1783. He became one of the most influential political and military leaders in the struggle against Spanish colonial rule in South America.

Bolívar is widely remembered by the title El Libertador, meaning “The Liberator.” He played a central role in the independence processes connected with present-day Venezuela, Colombia, Ecuador, Peru, Bolivia and Panama.

The country of Bolivia was named in his honour. His writings and political ideas remain important for questions on Latin American history, anti-colonial movements and republicanism.

3. Amelia Earhart Was Born – 1897

1897

A Pioneer of Aviation and Women’s Achievement

American aviator Amelia Earhart was born at Atchison, Kansas, on July 24, 1897. She became one of the most recognised figures in the history of aviation.

In 1932, Earhart became the first woman to fly solo and nonstop across the Atlantic Ocean. She was also the second person, after Charles Lindbergh, to achieve a solo nonstop transatlantic flight.

Earhart disappeared in July 1937 while attempting to fly around the world with navigator Fred Noonan. Her disappearance remains one of aviation history’s best-known unsolved mysteries.

Exam Point Born: July 24, 1897
Birthplace: Atchison, Kansas, USA
Major record: First woman to fly solo nonstop across the Atlantic
Record year: 1932
Disappeared: 1937
Do Not Confuse Amelia Earhart was the first woman to fly solo across the Atlantic. Charles Lindbergh had completed the first solo nonstop transatlantic flight by a person in 1927.

4. Machu Picchu Came to Wide International Attention – 1911

1911

Hiram Bingham’s Visit to the Inca Site

On July 24, 1911, American historian and explorer Hiram Bingham III reached Machu Picchu in Peru and later publicised the site internationally through research and writing.

It is more accurate to say that Bingham brought Machu Picchu to wide international attention rather than that he discovered an unknown place. Local residents already knew the site, and evidence shows that people had visited it before Bingham.

Machu Picchu is a major Inca archaeological complex in the Andes. It is important for questions on the Inca civilisation, Peru, archaeology, cultural heritage and UNESCO World Heritage Sites.

5. The Treaty of Lausanne Was Signed – 1923

1923

A Major Post–First World War Settlement

The Treaty of Lausanne was signed in Switzerland on July 24, 1923. It was concluded between Turkey and the Allied powers after the Turkish War of Independence.

The treaty replaced the unratified Treaty of Sèvres as the principal peace settlement concerning Turkey. It recognised Turkish sovereignty and settled several territorial, political, minority and financial questions arising from the collapse of the Ottoman Empire.

The Republic of Turkey was formally proclaimed later in the same year, on October 29, 1923. Students should therefore keep the treaty date and the republic date separate.

Exam Point Treaty: Lausanne

6. Apollo 11 Returned Safely to Earth – 1969

1969

Successful Completion of the First Crewed Moon-Landing Mission

On July 24, 1969, the Apollo 11 Command Module Columbia splashed down safely in the Pacific Ocean, completing humanity’s first successful crewed mission to land people on the Moon and return them to Earth.

The crew consisted of Neil Armstrong, Buzz Aldrin and Michael Collins. Armstrong and Aldrin had walked on the lunar surface, while Collins remained in lunar orbit in Columbia.

The astronauts were recovered by the aircraft carrier USS Hornet. They then entered quarantine because scientists initially wanted to guard against the remote possibility of unknown lunar biological contamination.

7. India’s Landmark Reform Budget Was Presented – 1991

1991

A Turning Point in Indian Economic Policy

On July 24, 1991, Finance Minister Dr. Manmohan Singh presented the Union Budget for 1991–92 under the government of Prime Minister P. V. Narasimha Rao.

India was facing a serious balance-of-payments and fiscal crisis. The Budget, together with the New Industrial Policy and related trade and exchange-rate measures, became a major part of the reform programme that moved the economy toward greater competition, private participation and integration with the global economy.

For examination purposes, these reforms are commonly remembered through the term LPG—Liberalisation, Privatisation and Globalisation. However, students should understand that the reforms consisted of several policy measures introduced over time, not a single Budget provision alone.
