In Hinduism, Prajapati (Sanskrit: प्रजापति (IAST: prajā-pati)) "lord of people" is a group Hindu deity presiding over procreation, and protection of life, thereby a King of Kings. Vedic commentators also identify him with the creator referred to in the Nasadiya Sukta.
According to later beliefs in the post-Vedic Era, the Prajapaties were elected democratically. Lord Vishnu was first elected democratically/unanimously as Prajapati (in the North of Aryavarta or Bharta) by all the Rishis and subjects of that era and sat on the throne of Prajapati. Thereafter, Lord Bràhma was elected as Prajapati (in the west of Aryavrat or Bharta), after which Lord Shankar (in the South of Aryavrat or Bharta) or Rudras were elected as Prajapaties. The throne of Prajapati succeeded further and there were about 26 Prajapaties, as mentioned in the Vedas.
Prajapati is a Vedic deity presiding over procreation, and the protection of life. He appears as a creator deity or supreme god vishvakarman above the other Vedic deities in RV 10 and in Brahmana literature. Vedic commentators also identify him with the creator referred to in the Nasadiya Sukta.
In later times, he is identified with Vishnu, Shiva, with the personifications of Time, Fire, the Sun, etc. He is also identified with various mythical progenitors, especially (Manu Smrti 1.34) the ten lords of created beings first created by Brahmā, the Prajapatis Marichi, Atri, Angiras, Pulastya, Pulaha, Kratu, Vasishtha, Prachetas or Daksha, Bhrigu, Nārada.
The Mahabharata mentions, in the words of celestial sage Narada, 14 Prajapatis (lit:caretakers of the Praja) Hiranyagarbha is the source of the creation of the Universe or the manifested cosmos in Indian philosophy, it finds mention in one hymn of the Rigveda (RV 10.121), known as the 'Hiranyagarbha sukta' and presents an important glimpse of the emerging monism, or even monotheism, in the later Vedic period, along with the Nasadiya sukta suggesting a single creator deity predating all other gods (verse 8: yó devéṣv ádhi devá éka âsīt, Griffith: "He is the God of gods, and none beside him."), in the hymn identified as Prajapati.
The Upanishads calls it the Soul of the Universe or Brahman, and elaborates that Hiranyagarbha floated around in emptiness and the darkness of the non-existence for about a year, and then broke into two halves which formed the Swarga and the Prithvi. In classical Puranic Hinduism, Hiranyagarbha is a name of Brahma, so called because he was born from a golden egg (Manusmrti 1.9), while the Mahabharata calls it the Manifest.
Śrīmad Bhāgavatam 8.8.16 cites Vishvakarman as the leader of the prajāpatis, the sons of Lord Brahmā who generate progeny. The eleven lords of created beings first created by Brahmā, which are the Prajapatis:
They are the caretakers of the fourteen worlds - seven lokas and seven talas.
The Prajapati community come brahmana warriors are seen as the descendants of Prajapati; Lord Brahmā, Lord Vishnu, Lord Shiva and Maharaj Manu are considered Prajapaties. Prajapati also means protector & preserver (King).

It has been argued that the name of /PRA-JĀ[N]-pati/ ('progeny-potentate') is etymologically equivalent to that of the oracular god at Kolophōn (according to Makrobios), namely /prōtogonos/.
According to Damascius, Prōtogonos (also known as Phanēs) had four heads, those of "a Serpent (Drakōn)... and a bull; a man, and a god," while in the Brahmāṇḍa Purāṇa Brahmā - identified with Prajapati in several texts - is likewise reckoned as 4-headed [one head each having produced deva-s (gods), ṛṣi-s (sages), pitṛ-s (ancestors), and nara-s (humans)].
