Kosala Kingdom in the context of "Satrughna"

Ikshvaku (Sanskrit Ikṣvāku; Pāli: Okkāka) is a legendary king in Indian religions, particularly Hindu and Jain scriptures. In Hinduism, he is described to be the first king of the Kosala Kingdom, and was one of the ten sons of Shraddhadeva Manu, the first man of the Shraddhadeva Manvantara (7th of the 14 in this Kalpa). He was the founder and first king of the Ikshvaku dynasty, also known as the Suryavamsha, in the kingdom of Kosala, which also historically existed in ancient India. He had a hundred sons, among whom the eldest was Vikukshi. Another son of Ikshvaku's, named Nimi, founded the Kingdom of the Videhas. and Rama are also stated to have belonged to the Suryavamsha or Ikshvaku dynasty.

Newar (/nɪˈwɑːr/; Newar: नेवार, endonym: Newa; Newar: नेवा, Pracalit script: 𑐣𑐾𑐰𑐵𑑅‎), or Nepami, are primarily inhabitants in Kathmandu Valley of Nepal and its surrounding areas, and the creators of its historic heritage and civilisation. Newars are a distinct linguistic and cultural group, primarily Indo-Aryan and Tibeto-Burman ethnicities, who share a common language, Nepal Bhasa, and predominantly practice Newar Hinduism and Newar Buddhism.Newars have developed a division of labour and a sophisticated urban civilisation not seen elsewhere in the Himalayan foothills. Newars have continued their age-old traditions and practices and pride themselves as the true custodians of the religion, culture and civilisation of Nepal. Newars are known for their contributions to culture, art and literature, trade, agriculture and cuisine. Today, they consistently rank as the most economically and socially advanced community in Nepal, according to the annual Human Development Index published by UNDP. Newars are ranked the 8th largest ethnic group in Nepal according to the 2021 Nepal census numbering 1,341,363 people constituting 4.6% of the total population.

The Kathmandu Valley and surrounding territories constituted the former Newar kingdom of the Nepal Mandala. Unlike other common-origin ethnic or caste groups in Nepal, the Newars are regarded as an example of a nation community with a relict identity, derived from an ethnically diverse, previously existing polity. The Newar community within it consists of various strands of ethnic, racial, caste and religious heterogeneity, as they are the descendants of the diverse group of people that have lived in Nepal Mandala since prehistoric times. Indo-Aryan tribes like Maithils of Madhesh Province, the Licchavis, Kosala, and Mallas (N) from respective Indian Mahajanapada (i.e. Licchavis of Vajji, Kosala, and Malla (I)) that arrived at different periods eventually merged with the local native population by marriage as well as adopting their language and customs. These tribes however retained their Vedic culture and brought with them their Sanskritic languages, social structure, Hindu religion and culture, which were assimilated with local cultures and gave rise to the current Newar civilisation. Newar rule in Nepal Mandala ended with its conquest by the Gorkha Kingdom in 1768.

The Solar dynasty or Sūryavanśha (lit. 'Descendants of the Sun'; Sanskrit: सूर्यवंश), also called the Ikshvaku dynasty, is a lineage or dynasty said to have been founded by Ikshvaku. In Hindu literature, it ruled the Kosala Kingdom, with its capital at Ayodhya, and later at Shravasti. They worshipped their clan deity, Surya (a Hindu solar deity), after whom the dynasty is named. Along with the Lunar dynasty, the Solar dynasty comprises one of the main lineages in Hinduism.

According to Jain literature, the first Tirthankara of Jainism, Rishabhanatha himself, was King Ikshvaku. Twenty-one further Tirthankaras were born in this dynasty.
