In Jain universal history, the 12 Cakravartins (universal emperors) of the present avasarpiṇī are listed in this chronological order: Bharata, Sagara, Maghavan, Sanatkumāra, Śānti, Kunthu, Ara, Subhūma/Subhauma, Mahāpadma/Padma, Hariṣeṇa, Jayasena, Brahmadatta. Jain texts say that Cakravartins are born in royal families, their rise is foretold by auspicious dreams, they perform world-conquest (digvijaya), and they possess the cakra and the 14 ratnas and 9 निधis/treasures. ( jainpedia.org)

Below is a scriptural-style summary of their lives, in the same order:

1. Bharata

He is the first Cakravartin and the son of the first Jina, Ṛṣabhanātha. His life is the classic Jain model of royal power, world-conquest, and eventual spiritual turning-point. The Bharata–Bāhubali episode is one of the most important stories in Jain Purāṇic literature. ( jainpedia.org)

1. Sagara

He is the second Cakravartin. Jain universal-history texts place him among the great imperial rulers whose careers are marked by conquest, immense armies, and the possession of the cakra and jewels. He is one of the earliest kings featured in Jain Purāṇic narrative tradition. ( jainpedia.org)

1. Maghavan

He is the third Cakravartin. Like the others, his story follows the pattern of royal birth, victory over surrounding rulers, and the rise of imperial authority through accumulated merit. ( jainpedia.org)

1. Sanatkumāra

He is the fourth Cakravartin. Jain tradition treats him as one of the great imperials whose life combines worldly sovereignty with the karmic possibility of renunciation. ( jainpedia.org)

1. Śānti

He is the fifth Cakravartin and later becomes the 16th Tīrthaṅkara, Śāntinātha. This is significant in Jain tradition: he first rules as a universal emperor, and then later renounces and attains Jina-hood. ( jainpedia.org)

1. Kunthu

He is the sixth Cakravartin and later becomes the 17th Tīrthaṅkara, Kunthunātha. His life is another example of the Jain theme that supreme worldly power can mature into supreme spiritual victory. ( jainpedia.org)

1. Ara

He is the seventh Cakravartin and later becomes the 18th Tīrthaṅkara, Aranātha. Jain texts place him among the rare figures who first attain universal kingship and later Jina-status. ( jainpedia.org)

1. Subhūma / Subhauma

He is the eighth Cakravartin. His name appears in the standard Jain list, and his life belongs to the same imperial pattern of conquest, glory, and karmic consequence. ( jainpedia.org)

1. Mahāpadma / Padma

He is the ninth Cakravartin. In Jain universal history, he continues the succession of emperors who rule by merit, discipline, and the support of the cakra and ratnas. ( jainpedia.org)

1. Hariṣeṇa

He is the tenth Cakravartin. Jain sources include him in the great chain of universal monarchs of this time-cycle. ( jainpedia.org)

1. Jayasena

He is the eleventh Cakravartin. His life is again part of the recurring Jain template of imperial victory and karmic destiny. ( jainpedia.org)

1. Brahmadatta

He is the twelfth and last Cakravartin of the present time-period. Jain tradition regards him as completing the current cycle of the twelve universal emperors. ( jainpedia.org)

Scriptural pattern common to all 12

Jain Purāṇic literature describes Cakravartins as beings with:

• royal birth
• auspicious dream-omens
• world-conquest (digvijaya)
• the appearance of the cakra in their armoury
• 14 ratnas and 9 nidhis
• many queens and sons
• a destiny that may end in heaven, liberation, or lower rebirth, depending on karmic development. ( jainpedia.org)

Important Jain doctrinal point

Among these 12, Śānti, Kunthu, and Ara are especially revered because they are not only Cakravartins but also later become Tīrthaṅkaras. Jain tradition uses them to show that worldly sovereignty is still inferior to liberation. ( jainpedia.org)
