Rakhaldas Bandyopadhyay excavated Mohenjo-daro in 1922. Daya Ram Sahni began the Harappa excavation in 1921, so choosing him mixes up the two sites. John Marshall was then Director-General of the Archaeological Survey and supervised the work. Cunningham was the Survey's first head, long before these digs.

The Rigveda has 10 mandalas and about 1028 hymns. It is not 8, 9 or 12; 9 is a common slip because the ninth mandala is wholly devoted to Soma. Mandalas 2 to 7 are regarded as the oldest (the family books), while the 1st and 10th were added later.

Mahavira (Vardhamana) is the 24th and last Tirthankara. Parshvanatha was the 23rd, so he is not the last. Rishabhanatha (Adinatha) was the first. Neminatha was the 22nd and is said to be a relative of Krishna.

The Buddha gave his first sermon to five disciples at Sarnath (Rishipattana), called the Dharmachakra Pravartana. At Bodh Gaya he attained enlightenment but did not preach. Lumbini is his birthplace and he attained Mahaparinirvana at Kushinagar.

The Kalinga War took place around 261 BCE, in the eighth year of Ashoka's reign. 321 BCE is when the Mauryan Empire began, 326 BCE is Alexander's invasion and 185 BCE is the fall of the Mauryas, so those are wrong. Horrified by the war, Ashoka turned to Buddhism, as Rock Edict XIII records.

The Greek ambassador Megasthenes wrote about Mauryan rule in his book "Indica". The other three are Chinese pilgrims who visited India much later, in the Gupta and Harsha periods.

The Arthashastra was written by Kautilya (Chanakya, Vishnugupta) and deals with statecraft and administration. Vishakhadatta wrote the play "Mudrarakshasa", Kalidasa "Abhijnanashakuntalam" and Banabhatta "Harshacharita". All four are authors, so the work-author pairs must be remembered.

Vincent Smith gave Samudragupta this title for his wide conquests. His deeds are recorded in the Allahabad Prashasti, composed by Harishena. Chandragupta I laid the foundation of the Gupta empire, Skandagupta held off the Huna invasions and Kumaragupta was a ruler of peace, so none of them is called this.

Qutb ud-Din Aibak founded the Delhi Sultanate (Slave dynasty) in 1206. Iltutmish was a later strong ruler who consolidated it rather than founded it. Balban and Alauddin Khalji came later still.

Muhammad bin Tughlaq moved the capital to Devagiri (renamed Daulatabad), but the plan failed. He also introduced token currency in copper and brass. Firuz Shah Tughlaq is known for canals and public works, Ghiyas ud-Din founded the dynasty, and Alauddin Khalji is famous for market price control.

Babur defeated Ibrahim Lodi at the First Battle of Panipat in 1526 and laid the foundation of the Mughal Empire. 1527 is the Battle of Khanwa against Rana Sanga, so it is a trap. 1556 and 1761 are the years of the Second and Third Battles of Panipat.

Maharana Pratap of Mewar fought the Mughal army at Haldighati in 1576; the Mughal commander was Man Singh. Rana Sanga fought Babur at Khanwa (1527), so he is wrong. Hemu fought at the Second Battle of Panipat (1556) and Shivaji was a Maratha leader of the 17th century.

Sher Shah Suri introduced the silver "Rupiya" and the copper "Dam". He also repaired the Grand Trunk Road. Alauddin Khalji fixed market prices, Akbar is known for the mansabdari system and Humayun was defeated by Sher Shah.

The Battle of Plassey was fought on 23 June 1757; Robert Clive led the Company and Siraj ud-Daulah lost through Mir Jafar's betrayal. 1764 is the Battle of Buxar, which secured the Company's power. In 1756 Siraj captured Calcutta, and 1772 is when Warren Hastings took charge.

On 10 May 1857 the sepoys at Meerut rebelled and marched to Delhi, so the Revolt began at Meerut. Mangal Pandey's incident at Barrackpore came earlier, in March, but was an isolated event. Delhi was the main centre of the revolt, not its starting point, and at Kanpur Nana Saheb led it.

Womesh Chunder Bonnerjee presided over the first session (Bombay, December 1885). A. O. Hume was one of the founders and the first general secretary, not the president. Dadabhai Naoroji was president three times, first in 1886. Surendranath Banerjee became president in 1895.

The Partition of Bengal took effect on 16 October 1905 under Lord Curzon. After the strong Swadeshi movement it was annulled in 1911, when Lord Hardinge was Viceroy. Ripon is known for local self-government, Dalhousie for the Doctrine of Lapse and Bentinck for abolishing sati.

On 13 April 1919, on General Dyer's orders, an unarmed crowd was fired upon at Jallianwala Bagh, during a gathering protesting the Rowlatt Act. The Champaran Satyagraha was in 1917, the Kheda Satyagraha in 1918, and Gandhi started the Non-Cooperation Movement in 1920.

Gandhi marched from Sabarmati Ashram to Dandi in Gujarat and broke the salt law there on 6 April 1930, starting the Civil Disobedience Movement. Sabarmati was the starting point, not the end. Champaran (1917) and Bardoli (1928) are sites of other movements.
