Jayasimha Siddharaja

The Chaulukya dynasty (IAST: Caulukya), also Solanki dynasty, was a dynasty that ruled parts of what are now Gujarat and Rajasthan in north-western India, between c. 940 CE and c. 1244 CE. Their capital was located at Anahilavada (modern Patan). At times, their rule extended to the Malwa region in present-day Madhya Pradesh. The family is also known as the "Solanki dynasty" in the vernacular literature. They belonged to the Solanki clan of Rajputs.

Mularaja, the founder of the dynasty, supplanted the last ruler of the Chavda dynasty around 940 CE. His successors fought several battles with the neighbouring rulers such as the Chudasamas, the Paramaras and the Chahamanas of Shakambhari. During the reign of Bhima I, the Ghaznavid ruler Mahmud invaded the kingdom and raided the Somnath temple during 1024–1025 CE. The Chaulukyas soon recovered, and the kingdom reached its zenith under the rule of Jayasimha Siddharaja and Kumarapala in the 12th century. Several minor dynasties, such as the Chahamanas of Jalor and the Chahamanas of Naddula, served as Chaulukya vassals during this period. After Kumarapala's death, the kingdom was gradually weakened by internal rebellions; uprisings by feudatories; and invasions by the Paramaras, the Ghurids, the Yadavas and others. Taking advantage of this, the Vaghelas, who had earlier served as Chaulukya generals, usurped the power and established a new dynasty in the 1240s.

Old Western Rājasthāni (also known as Maru-Gurjari, Old Gujarātī) is the common ancestor of the modern Gujarati and Western Rajasthani languages which developed from Sanskrit and the Prakrit Apabhraṃśas, and was spoken around 8-14th centuries in Western India. The literary form of Old Western Rājasthāni, the Dingala language was in use as early as the 12th century. While the spoken Old Western Rajasthani gave way to medieval forms of Western Rajasthani and Gujarati, it flourished in its literary form as Dingala till the 19th century.

Early texts of the language display characteristic features such as direct/oblique noun forms, postpositions, and auxiliary verbs. It had three genders, as Gujarati does today, and by around the time of 1300 CE, a fairly standardized form of this language emerged. The belief that modern Rajasthani sporadically expressed a neuter gender was based on the incorrect conclusion that the [ũ] that came to be pronounced in some areas for masculine [o] after a nasal consonant was analogous to Gujarati's neuter [ũ]. A formal grammar, Prakrita Vyakarana, of the precursor to this language, Gurjar Apabhraṃśa, was written by Jain monk and eminent scholar Acharya Hemachandra Suri in the reign of Chaulukya king Jayasimha Siddharaja of Anhilwara (Patan).

The Chudasama dynasty, a Samma branch, ruled parts of the present-day Saurashtra region of Gujarat state in India between the 9th and 15th centuries. Their capital was based in Junagadh and Vamanasthali.

The early history of the Chudasama dynasty is almost lost. The bardic legends differ very much in names, order and numbers and so are not considered reliable. Traditionally, the dynasty is said to have been founded in the late 9th century by Chudachandra. Subsequent rulers such as Graharipu, Navaghana and Khengara were in conflict with Chaulukya rulers Mularaja and Jayasimha Siddharaja. Thus they are mentioned in contemporary and later Jain chronicles. After the end of Chaulukya rule and that of their successor Vaghela dynasty, the Chudasamas continued to rule independently or as vassals of the successor states, the Delhi Sultanate and Gujarat Sultanate. The first known Chudasama ruler recorded in inscriptions was Mandalika I, during whose reign Gujarat was invaded by the Khalji dynasty of Delhi. The last king of the dynasty, Mandalika III, was defeated and forcibly converted to Islam in 1472 by Sultan Mahmud Begada, who also annexed the state.
