Sri Rama or Sri Ram (राम) (రామ) or sri Raamar (Tamil) is the seventh avatar of the God Vishnu in Hinduism, and a king of Ayodhya in Hindu scriptures. Along with Krishna, the eighth avatar of Vishnu, Sri Ram is considered to be the most important avatar of Vishnu. He is also one of the most popular gods in Hinduism and is widely worshipped throughout Nepal and India. In a few Ram-centric sects, he is considered the Supreme Being, rather than an avatar of Vishnu. Sri Ram was born in Suryavansha (Ikshvaku Vansham) later known as Raghuvansha after king Raghu. When depicted with his brother Lakshman and consort Sita, with Hanuman kneeling in a state of prayer, this form is called Ram Parivar, and is the typical fixture depicting Sri Ram in Hindu temples. The Hindi word parivar translates as "family." 
SriRama is one of the many popular figures and deities in Hinduism, specifically Vaishnavism and Vaishnava religious scriptures in South andSoutheast Asia. In Ayodhya, the Indian city believed to be the birthplace of Sri Ram, he is also worshipped as an infant or Sri Rama Lalla. Most of the details of SriRama's life come from the Ramayana, one of the two great epics of India.
Born as the eldest son of Kausalya and Dasharatha, king of Ayodhya, Ram is referred to within Hinduism as Maryada Purushottama, literally the Perfect Man or Lord of Self-Control or Lord of Virtue. Ram is the husband of Sita, whom Hindus consider to be an Avatar of Lakshmi and the embodiment of perfect womanhood.
Sri Ram's life and journey is one of perfect adherence to dharma despite harsh tests of life and time. He is pictured as the ideal man and the perfect human. For the sake of his father's honour, Ram abandons his claim to Kosala's throne to serve an exile of fourteen years in the forest. His wife Sitaand brother Lakshmana, unable to live without Ram, decide to join him, and all three spend the fourteen years in exile together. While in exile, Sita is kidnapped by Ravana, the Rakshasa monarch of Lanka. After a long and arduous search that tests his personal strength and virtue, Ram fights a colossal war against Ravana's armies. In a war of powerful and magical beings, greatly destructive weaponry and battles, Ram slays Ravana in battle and liberates his wife. Having completed his exile, Ram returns to be crowned king in Ayodhya (the capital of his kingdom) and eventually becomes emperor, rules with happiness, peace, prosperity and justice—a period known as Ram Rajya.
SriRama's courage in searching for Sita and fighting a terrible war to rescue his wife and their honour is complemented by Sita's absolute devotion to her husband's love, and perfect chastity despite being Ravana's captive. SriRama's younger brothers, namely Lakshmana, Shatrughna and Bharatastrongly complement his piety, virtue and strength, and they are believed by many to belong to the Maryada Purushottama and the Seventh Avatara, mainly embodied by SriRama. SriRama's piety and virtue attract powerful and devoted allies such as Hanuman and the Vanaras of Kishkindha, with whose help he rescues Sita. The legend of SriRama is deeply influential and popular in the societies of the Indian subcontinent and across South East Asia. SriRama is revered for his unending compassion, courage and devotion to religious values and duty.
