With reference to Indian history, consider the following statements: 1. The first Mongol invasion of India happened during the reign of Jalal-ud-din Khalji. 2. During the reign of Ala-ud-din Khalji, one Mongol assault marched up to Delhi and besieged the city. 3. Muhammad-bin-Tughlaq temporarily lost portions of north-west of his kingdom to Mongols. Which of the statements given above is/are correct?

This snippet records Mongol raids on Delhi during Ala-ud-din's rule (1298 onward), showing major Mongol incursions into North India by the late 13th century.

A student could compare the date of Ala-ud-din's confrontations (circa 1298–1305) to the reign of Jalal-ud-din Khalji (earlier Khalji ruler, 1290–1296) to judge whether these raids were the first.

This snippet says Iltutmish diplomatically refused to support Khwarizmi Shah Jalaluddin against the Mongols, implying Mongol activity and threats were present in the region earlier (Iltutmish ruled 1211–1236).

A student could use Iltutmish's reign dates to infer Mongol pressure on the subcontinent predates the Khalji period, so the 'first' Mongol contact might be earlier than Jalal-ud-din Khalji's reign.

This states Ala-ud-din Khilji repelled several Mongol invasions at the turn of the 14th century, indicating repeated Mongol attempts to enter India around 1300.

By placing these Ala-ud-din defenses (circa 1300) on a timeline alongside Jalal-ud-din Khalji's reign (1290–1296), a student can test whether the 'first' recorded Mongol invasion falls before, during, or after Jalal-ud-din.

The summary gives a concise sequence: establishment of Delhi Sultanate in 1206 and major invasions in previous centuries, providing a framework of successive external incursions into India.

Using this timeline framework a student can place Mongol incursions relative to Sultanate dynasties (Slave, Khalji, etc.) to assess when the first Mongol invasion likely occurred.

Notes that invasions from beyond the Hindu Kush reshaped India's political map, highlighting that incursions across that frontier (the Mongol route) were a recurring phenomenon.

A student could combine this geographic pattern with rulers' dates to see which reigns coincide with documented crossings of the Hindu Kush by Mongol forces.
