The conversion of the vestment into a coronation mantle

Due to its rich decoration and its relation to King Saint Stephen, the vestment became a coronation mantle.
The coronation happened within the frame of a holy mass. The ceremony began with the consecration of the King, by anointing him with sacred oil to indicate that the King reigns according to the will of God.
The conversion happened during the reign of Béla III. From this time the history of the mantle was connected to the history of the Holy Crown. The coronation mantle and the Holy Crown, with the royal sceptre, the globus cruciger (orb and cross) and the coronation sword constitute the regalia, which were guarded by the church in Székesfehérvár until the 14th century.
