Poosapati / Pusapati was the ruling clan of the Northern Andhra region, Vizianagaram.
The Pericchedi kings were ancestors of the Pusapati royal family who built Bezawada (Modern Vijayawada) off the river Krishna by 626 AD and another capital in Kollipaka establishing themselves for nine centuries there. The family name was changed to Pusapati after moving to the coastal region. The first Pusapati chieftain Sitaram Raju received the villages of Kumuli and Gundredu from Maharaja Krishan Dev of Jeypore kingdom.  Viziaram Raz served as the minister in the court of Maharaja Ram Chandra Dev and later founded the city of Vizianagaram after occupying some of the coastal territories of Jeypore due to a feud between the king and his brother, Balaram Dev III. Viziaram also led the other zamindars gain independence from the feudalism of Jeypore.
Vizianagaram is named after this Pusapati Vijay Rama Raju and is spelled with a Z to differentiate it from the Vijayanagar Dynasty in Hampi. They obtained the title of Gajapathi in the 16th century, after defeating the Gajapatis of Jeypore in the battle of Nandapur (old capital of Jeypore), in the Northern Circars, and have used since then.
Emperor Aurangzeb gave them a two-edged sword 'pattaa kaththi' (Telugu:పట్టాకత్తి) (Zulfiqar), which is still used in the coat-of-arms of the family. By 1713 they erected the fort at Vizianagaram where they have since resided. In 1827 Maharajah Vijay Rama Gajapati Raju III. had several honors conferred on him by the British Government. Lord Northbrook obtained for him the title of His Highness, and had his name enrolled among those of chiefs entitled to return visits from the Viceroy with a 13 gun salute.
