Jainism divides time into vast cycles called Utsarpini (ascending half-cycle) and Avasarpini (descending half-cycle). In each Avasarpini, according to Jain texts, there are 12 Chakravartis (universal monarchs). The 6th Chakravarti of the current Avasarpini is Mahapadma.

Janmasthali (birthplace): According to Jain tradition, Mahapadma Chakravarti was born in Ayodhya. This is mentioned in several Jain scriptures such as the Trishashti Shalaka Purusha Charitra by Acharya Hemchandra.

So, the birthplace of the 6th Chakravarti of the current Avasarpini (Mahapadma Chakravarti) is Ayodhya.
