The Origin of the Rashtrakuta dynasty has been a controversial topic and has been debated over the past decades by historians. The differing opinions mostly revolve around issues such as the home of the earliest ancestors of the medieval Rashtrakutas, a possible southern migration during the early part of the first millennium and the relationship between the several Rashtrakuta dynasties that ruled small kingdoms in northern and central India and the Deccan in the 6th century - 7th century. Further, the relationship of these medieval Rashtrakutas to the most important and famous dynasty, the Rashtrakutas of Manyakheta of the 8th century - 10th century time period has also been debated. Also contested is whether the Rashtrakutas of Manyakheta were related by ancestry to the early Kannada and Maratha communities of the Deccan or other ethnic groups of northern India.
While the history of the early Rashtrakutas has caused much debate, the history of the Rashtrakutas of Manyakheta (in present-day Gulbarga) of the 8th–10th centuries can be accurately constructed because numerous contemporaneous inscriptions and texts refer to them. The crux of the Manyakheta empire extended from the Kaveri river in the south to the Narmada in the north. At their peak they were the only south Indian empire that conquered regions in far northern India (Kannauj) as well as the extreme south (Tamilakam). The Lata branch of the empire (in present-day Gujarat) was an important dynasty belonging to the Manyakheta family line which later merged with the Manyakheta kingdom during the 9th century.
