Shri Krishna married 16000 wives – Srimad Bhagavatam

📖Srimad Bhagavatam 10.69.1-6
Śukadeva Gosvāmī said: Hearing that Lord Kṛṣṇa had killed Narakāsura and had alone married many brides, Nārada Muni desired to see the Lord in this situation. He thought, “It is quite amazing that in a single body Lord Kṛṣṇa simultaneously married sixteen thousand women, each in a separate palace.” Thus the sage of the demigods eagerly went to Dvārakā.

• Now if you include the other eight queens of Krishna that He had married earlier the number becomes 16,008. So as per puranas Krishna indeed has 16,108 wives.

📖Srimad Bhagavatam 10.58.56
Bhadrā was a princess of the Kaikeya kingdom and the daughter of Lord Kṛṣṇa’s paternal aunt Śrutakīrti. The Lord married Bhadrā when her brothers, headed by Santardana, offered her to Him.

• Bhadrā was a princess of the Kaikeya kingdom and the daughter of Lord Kṛṣṇa’s paternal aunt, Śrutakīrti. And Lord Krishna married Bhadrā.

Rigveda 10:85:45
Indra, showerer, make her the mother of sons, plural asing (to her husband); give her ten sons, make herhusband the eleventh.

Srimad Bhagavatam 10.61.1
Śukadeva Gosvāmī said: Each of Lord Kṛṣṇa’s wives gave birth to ten sons, who were not less than their father, having all His personal opulence.

• Birth and marriage in Hinduism are considered acts of devotion. Krishna, who is worshipped by billions of Hindus, is said to have had so much power that he had intercourse with over 16,000 girls and fathered more than 100,000 children with his wives. Krishna and his sons were considered incredibly powerful, and their strength cannot be compared with anyone else. However, the teachings of this story suggest that Hindus should marry and have as many children as possible, following Krishna’s example. In fact, one verse indicates that Krishna had 16,108 wives and fathered 161,080 sons.

Srimad-Bhagavatam 1.14.31
Are all the chieftain sonsof Lord Kṛṣṇa, such as Suṣeṇa, Cārudeṣṇa, Sāmba the son of Jāmbavatī, and Ṛṣabha, along with their sons, all doing well?

• As already mentioned, Kṛṣṇa married 16,108 wives, and each of them had ten sons. Therefore 16,108 × 10 = 161,080 sons. They all grew up, and each of them had as many sons as their father, and the whole aggregate was something near 1,610,800 family members of the Lord.
