Hagi I Giray (ruled circa 1441-1466, lived 1397-1466) was the founder of the Crimean Khanate and the Giray dynasty of Crimea.
As the Golden Horde was breaking up he established himself in Crimea and spent most of his life fighting off other warlords.
He was usually allied with the Lithuanians.
His name has many spellings, such as Melek Haji Girai (Crimean Tatar: Bir Haci Geray, ???-???? ??????; Melek Haci Geray, ??? ???? ?????).
He is said to have introduced the new state symbol: "taraq tamga" or "the trident of Girays", which is derived from the scales insignia of the Golden Horde.
A contemporary European source, The Chronicle of Dlugosz, described him as a person of outstanding personal values and a perfect governor.
