Ujjain (/uːˈdʒeɪn/; About this sound listen ) is the largest city in Ujjain district of the Indian state of Madhya Pradesh. It is the fifth largest city in Madhya Pradesh by population and is the administrative centre of Ujjain district and Ujjain division.
An ancient city situated on the eastern bank of the Kshipra River, Ujjain was the most prominent city on the Malwa plateau of central India for much of its history. It emerged as the political centre of central India around 600 BCE. It was the capital of the ancient Avanti kingdom, one of the sixteen mahajanapadas. It remained an important political, commercial and cultural centre of central India until the early 19th century, when the British administrators decided to develop Indore as an alternative to it. Ujjain continues to be an important place of pilgrimage for Shaivites, Vaishnavites and followers of Shakta.
Ujjain has been selected as one of the hundred Indian cities to be developed as a smart city under PM Narendra Modi's flagship Smart Cities Mission.
