Raja (/ˈrɑːdʒɑː/; from IAST rājan-) is a noble or royal Sanskrit title historically used by some Indian rulers and monarchs and highest-ranking nobles. The title was historically used in the Indian subcontinent and Southeast Asia.
The title has a long history in South Asia and Southeast Asia, being attested from the Rigveda, where a rājan- is a ruler, see for example the daśarājñá yuddhá, the "Battle of Ten Kings".
