The break-up of the Gurjara-Pratihara empire led to a phase of political uncertainty in north India. As a result, little attention was paid to the emergence of the aggressive and expansionist Turks.
Rajputana States
The three most important of the Rajput states in north India were the Gahrwals of Kanauj, the Paramaras of Malwa and the Chauhans of Ajmer. There were other smaller dynasties in different parts of the country, such as the Kalachuris in the area around Jabalpur, the Chandellas in Bundelkhand, the Chalukyas of Gujarat, the Tomars of Delhi, etc. Bengal remained under the control of the Palas and later, the Senas. There was a continuous struggle and warfare between the various Rajput states
It was these rivalries which made it impossible for the Rajput rulers to join hands to oust the Ghaznavids from the Punjab. In fact, the Ghaznavids felt strong enough to make raids even up to Ujjain.
Most of the Rajput rulers of the time were champions of Hinduism, though some of them also patronized Jainism. The Rajput rulers protected the privileges of the brahmanas and of the caste system. Between the tenth and the twelfth century, temple-building activity in north India reached it's climax. The most representative temples of this type are the group of temples at Khajuraho in Madhya Pradesh. Most of these temples were built by the Chandellas, who ruled in the area from the beginning of the ninth to the end of the thirteenth century. In Orissa, magnificent examples of temple architecture are the Lingaraja temple (11th century) and the Sun temple of Konark (13th century). The famous Jagannath temple at Puri also belongs to this period.
Mahmud of Ghazni
Mahmud of Ghazni raided the country in 1000 AD, with his first great victory against the Hindushahi kings of Peshawar. The muslim rulers of Multan were the second targets. In a short period of 25 years, he is said to have made 17 raids into India. From the Punjab, Mahmud raided Nagarkot in the Punjab hills and Thanesar near Delhi. His most daring raids, however, were against Kanauj in 1018 and against the fabulously rich Somnath temple in Gujarat. No attempt was made to annex any of these areas. The rich spoils from the temples, which were repositories of wealth, helped him to consolidate his rule and embellish Ghazni with palaces and mosques. He died in Ghazni in 1030.
Muhammad of Ghori
The second Turkish attack was led by Mu'izzu'd-Din Muhammad (also known as Muhammad Ghori), who conquered Sindh and Lahore in 1182. Soon after, he commenced his attack on the Rajput kingdoms. Prithviraj Chauhan successfully led the Rajputs against Ghori at the first battle of Tarain in 1191 AD. However, at the second battle in 1192 AD, Prithviraj was defeated and the kingdom of Delhi fell to Muhammad Ghori. Before Ghori's assassination in 1206, Turkish control had been established along the whole length of the Ganga. Bihar and Bengal were also overrun.
Ghori's conquest became the nucleus of a new political entity of India - the Delhi Sultanate. For almost one hundred years after that, the Delhi Sultanate was involved in foreign invasions, internal conflicts among the Turkish leaders and the dispossessed Rajput rulers and chiefs to regain their independence.
Ghori left his Indian possessions in the care of his former slave, General Qutb-ud- din Aibak. He played an important part in the expansion of the Turkish sultanate in India after the battle of Tarrain. On the death of his master, Aibak severed his links with Ghazni and asserted his independence, and founded Slave Dynasty mamluks. This helped to prevent India being drawn into central asian politics and enabled the Delhi Sultanate to develop independently.
Iltutmish (1210 AD - 1236 AD), son-in-law of Aibak - succeeded Aibak as the sultan by defeating Aibak's son. Thus, the principle of heredity, of son succeeding his father was checked at the outset. Iltutmish must be regarded as the real consolidator of the Turkish conquests in north India. He gave the new state capital, Delhi, a monarchical form of government and governing class. He introduced Iqta - grant of revenue from a territory in lieu of salary. He maintained a central army and introduced coins of Tanka (silver) and Jital (copper). The famous Qutub Minar was completed during his reign. He despatched an expedition against the Chalukyas of Gujarat but it was repelled with losses.
During his last years, Iltutmish finally nominated his daughter Raziya (1236 AD - 1239 AD) to the throne. In order to assert her claim, Raziya had to contend against her brothers as well as against powerful Turkish nobles, and could rule only for three years. Though brief, her rule had a number of interesting features like the beginning of the struggle for power between the monarchy and the Turkish chiefs, sometimes called as the forty or Chahalgami. She sent an expedition against Ranthambhor to control the Rajputs, and successfully established law and order in the length and breadth of her kingdom. In 1239 AD, an internal rebellion broke out in which Raziya was imprisoned and killed by bandits.
The struggle between the monarchy and the Turkish chiefs continued till one of the Turkish chiefs Balban (Ulugh khan) (1265 AD - 1285 AD) ascended the throne. During the earlier period he held the position of naib or deputy to Nasiruddin Mahmud, a younger son of Iltultmish. He broke the Chahalgami and made the Sultan all important. Through changes in the organisation of the army and administration, he was able to control any revolt among the nobles. Balban got rid of many of his other rivals by fair and foul means. But there is no doubt that with his accession to the throne there began an era of strong, centralised government.
After Balban's death, there was again confusion in Delhi for some times. In 1290, the Khilji's, under the leadership of Jalaluddin Khilji, wrested power from the incompetent successor of Balban.
