SB 12.1 Summary
Please note: The summary and following translations were composed by disciples of Śrīla Prabhupāda
The Twelfth Canto of Śrīmad-Bhāgavatam begins with Śrīla Śukadeva Gosvāmī predicting the kings of the earth who will appear in the future during the age of Kali. Then he gives a description of the numerous faults of the age, after which the presiding goddess of the earth sarcastically berates the foolish members of the kingly order who perpetually try to conquer her. Next Śukadeva Gosvāmī explains the four varieties of material annihilation, and then he gives his final advice to Mahārāja Parīkṣit. Thereafter King Parīkṣit is bitten by the snake-bird Takṣaka and leaves this world. Sūta Gosvāmī concludes his narration of Śrīmad-Bhāgavatam to the sages at Naimiṣāraṇya forest by enumerating the teachers of the various branches of the Vedas and Purāṇas, relating the pious history of Mārkaṇḍeya Ṛṣi, glorifying the Supreme Lord in His universal form and in His expansion as the sun-god, summarizing the topics discussed in this literature, and offering final benedictions and prayers.
The first chapter of this canto briefly describes the future kings of the dynasty of Magadha and how they become degraded because of the influence of the age of Kali. There were twenty kings who ruled in the family of Pūru, in the dynasty of the sun-god, counting from Uparicara Vasu to Purañjaya. After Purañjaya, the lineage of this dynasty will become corrupted. Following Purañjaya there will be five kings known as the Pradyotanas, who are then followed by the Śiśunāgas, the Mauryas, the Śuṅgas, the Kāṇvas, thirty kings of the Andhra nation, seven Ābhīras, ten Gardabhīs, sixteen Kaṅkas, eight Yavanas, fourteen Turuṣkas, ten Guruṇḍas, eleven Maulas, five Kilakilā monarchs and thirteen Bāhlikas. After this, different regions will be ruled over at the same time by seven Andhra kings, seven Kauśalas, the kings of Vidūra, and the Niṣadhas. Then the power of rulership in the countries of Magadha and so forth will fall to kings who are no better than śūdras and mlecchas and are totally absorbed in irreligion.
