Frieze of King Sagar's great-great-grandson, Bhagiratha in penance.
The following is a list, in chronological order, of some of the prominent monarchs of the dynasty;
Manu or Vaivasvata Manu: the king of all mankind and the first human being on Earth. (According to Hindu belief there are 14 Manvantaras; in each, Manu rules.) Vaivasvata Manu was the seventh Manu. Manu is referred to as a Rajan (King) in the Shatapatha Brahmana scripture. He had nine sons, Vena, Dhrishnu, Narishyan, Nabhaga, Ikshvaku, Karusha, Saryati, Prishadhru, Nabhagarishta and one daughter, Ila, who was married to Budha of the Lunar Dynasty. He left the kingdom to the eldest male of the next generation, Ikshvaku, who was actually the son of Manu's brother Shraaddev.
Kakuthstha: The son of Vikukshi. His old name was Puranjaya. Infused with Vishnu's divine prowess, Puranjaya defeated all the Daityas and Asuras while riding on the shoulders of Indra, who was in the form of a white humped bull.
Mahabhisha: A king of Ayodhya who performed a thousand Ashwamedhas and a hundred Rajasuyas and ascended heaven. He was cursed to be reborn on earth for insolently looking at the goddess Ganga when the winds blew her clothes away, exposing her. Mahabhisha was reborn as Shantanu, King of Hastinapura. Shantanu married Ganga and sired the mighty Bhishma, the most powerful warrior of all time.
Mandhata: The son of Yuvanaswa. He was conceived when his father, Yuvanaswa mistakenly drank sacred water and became pregnant. The divine Aswini twins performed a Caesarean on Yuvanaswa and Mandhata was born. After being suckled with divine milk from Indra's hand, Mandhata grew up to be a twenty foot tall twelve year boy in twelve days. Trained by Indra in combat, Mandhata single handedly conquered the whole world in one day and performed many sacrifices and charity. He vanquished Indra in battle. He had three sons and fifty daughters. Mandhata's daughters fell in love with the extremely handsome sage Saubhari and gave him many sons and grandsons.
Sagara: Ayodhya was once conquered by Mlecchas and drove away its ruler, Bahu to the forests. Bahu perished due to old age and his younger queen was pregnant. Jealous, the elder queen, before dying, gave the junior queen poison and delayed the birth by seven years. Throught the power of the Sage Aurva of Bhrigu's race, the queen gave birth to a baby born with poison in his hand. Hence his name was Sagara (born with poison). Aurva took Sagara as his disciple and trained him in scriptures and weapons. When Sagara learnt his origins from his mother, he became enraged and nearly exterminated the Mlecchas from Ayodhya. He married two wives and acquired 60,001 sons from the grace of Mahadeva, who turned out to be violent and cruel. Sagara performed hundred Ashwamedhas. When the sacrifical horse was stolen, the wicked 60,000 sons of Sagara dug up massive tracts of the earth, which filled with he first oceans (Sagara); and massacred many people in the process. They were eventually reduced to ashes by Sage Kapila. Only the kind hearted Amshumantha, the sole grandson of Sagara who was alone worthy of being king succeeded in pacifying Kapila and brought back the horse. Amshumantha's grandson, Bhagiratha succeeded in washing those sins of his forefathers.
Bhagiratha: Sagara's great-grandson, after performing strenuous penances for a thousand years, at last succeeded in bringing Ganges down from Heaven. When she flowed over the remains of his ancestors, their souls were redeemed, and the ocean was refilled. Ganges bears the name "Bhagirathi", in honour of his deed. For his pious acts, Bhagiratha went to the Brahmaloka after his death.
Raghu: He was a legendary king and the great grandfather of Rama. As a youth, Raghu was guarding the sacrifical horse for his father's hundredth Ashwamedha Yagna. Indra, the King of the Gods feared that Raghu's father would become more powerful than him upon the completion of the sacrifice, and stealthily stole the horse. Raghu was enraged and the two engaged in a duel, where Raghu thwarted all of Indra's attacks. Indra hurled his Vajra (thunderbolt) at Raghu and knocked him senseless. Raghu quickly jumped back on to his feet, but Indra had run away out of fear. Raghu's father was proud of his son's valor and crowned him king. Raghu conquered the world and was so powerful, even the gods feared his prowess in battle.
Aja: Raghu's son, Aja conquered the world when the kings began to rebel against Raghu. Aja acquired a divine spear from a Gandharva which could put entire armies to sleep. He won princess Indumati's hand in marriage at a Swayamvara and defeated all the kings who opposed the union. Aja sired Dasharatha.
Rama: He is considered the seventh Avatar of the god Vishnu. He is worshiped by every Hindu. Many Hindus include his name in either their first or last name. Rama acquired celestial weapons from the Brahmarshi Vishwamitra and slew the Rakshasa King Ravana (who was dreaded by the gods) in battle. Rama's story before he became king of Ayodhya is recounted in the Ramayana. After slaying Ravana, Rama acquired a boon of invincibility from Brahma. After he ascended the throne, he performed the Ashwamedha Yajna. Bharata, his younger brother, won the country of Gandhara and settled there. Rama's other brother, Shatrughna founded the kingdom of Mathura. Rama became a powerful World Emperor and performed a hundred Ashwamedha Yagnas and a Jaruthya Yagna. He ruled for 11,000 years and his reign was the most perfect one of all time.
Lava and Kusha: They were the twin sons of Rama and his wife Sita. Lava ruled south Kosala while Kusha ruled north Kosala, including Ayodhya. Kusha married "Nagkanya" "Kumuddhati", sister of Kumuda.
Śuddhodana, leader of the Shakya Ganarajya at Kapilavastu. His son was Siddhartha Shakya, founder of Buddhism and came to be known as Gautam Buddha.
