Kachhwaha in the context of "Kingdom of Amber"

Jaipur (Rajasthani: Jayapura, pronounced [ˈd͡ʑɛpʊɾᵊ]) is the capital and the largest city of the north-western Indian state of Rajasthan. As of 2011, the city had a population of 3.1 million, making it the tenth most populous city in the country. Located 268 km (167 miles) from the national capital New Delhi, Jaipur is also known as the Pink City due to the dominant color scheme of its buildings in the old city.

Jaipur was founded in 1727 by Sawai Jai Singh II, the Kachhwaha Rajput ruler of Amer, after whom the city is named. It is one of the earliest planned cities of modern India, designed by Vidyadhar Bhattacharya. During the British colonial period, the city served as the capital of Jaipur State. After Indian independence in 1947, Jaipur became the capital of the newly formed state of Rajasthan in 1949.

The Kingdom of Amber, later the Kingdom of Jaipur, was located in the north-eastern historic Dhundhar region of Rajputana and was ruled by the Kachwaha Rajput clan. It was established by Rao Dulha Rai, possibly the last ruler of the Kachchhapaghata dynasty of Gwalior who later migrated from Narwar to Dausa and started his kingdom there with the support of Chahamanas of Shakambhari with coalition of Gaur dynasty of sheopur in the 11th century. Mostly through 11th to 15th century, the kingdom faced stagnation, and resources were scarce. Under Samrat Prithviraj Chauhan, its Raja Pajjwan dev of Ajmer, battled Muhammad Ghori. Raja Chandrasen of Amber became a Sisodia under him and fought in the Battle of Bayana and The Battle of Khanwa under Raja Prithviraj Kachhwaha.

Under Raja Bharmal, the kingdom heavily aligned with the Mughals and Akbar. His son and grandson Raja Bhagwant Das and Raja Man Singh I were leading generals in Akbar's army and helped him in expanding the empire. Mirza Raja Jai Singh I served under Shah Jahan and became a distinguished general. He fell out of Aurangzeb's favour when he was suspected of helping Shivaji escape from Mughal captivity in 1664. Sawai Jai Singh II became the ruler during the decline of the Mughal Empire. He successfully rebelled against the Mughals in 1708 to regain his confiscated kingdom. After Jai Singh's death, the kingdom was drained of its resources during the civil war amongst his sons Ishwari Singh and Madho Singh I and the Marathas.

Mirza Raja Jai Singh I (15 July 1611 – 28 August 1667) was the Kachhwaha Rajput ruler of the Kingdom of Amber as well as a senior most general and a high-ranking mansabdar at the imperial court of Mughal Empire. His predecessor was his grand uncle, Mirza Raja Bhau Singh, the younger son of Mirza Raja Man Singh I.
