In Jainism, a Tirthankara is a saviour and supreme spiritual teacher of the dharma. The word tirthankara signifies the founder of a tirtha, a fordable passage across saṃsāra, the sea of interminable birth and death. According to Jains, tirthankaras are the supreme preachers of dharma, who have conquered saṃsāra on their own and made a path for others to follow. After understanding the true nature of the self or soul, the Tīrthaṅkara attains kevala jnana (omniscience). A Tirthankara provides a bridge for others to follow them from saṃsāra to moksha (liberation).

Jainism, also known as Jain Dharma, is an Indian religion. Jainism traces its spiritual ideas and history through the succession of twenty-four tirthankaras, with the first in the current time cycle being Rishabhadeva, whom the tradition holds to have lived millions of years ago, the twenty-third tirthankara Parshvanatha, whom historians date to the 9th century BCE, and the twenty-fourth tirthankara Mahavira, around 600 BCE. Jainism is considered an eternal dharma with the tirthankaras guiding every time cycle of the cosmology. The three main pillars of Jainism are ahiṃsā (non-violence), anekāntavāda (non-absolutism), and aparigraha (asceticism).
