With his father's accession to the throne of England in 1603, Henry at once became Duke of Cornwall. In 1610 he was further invested as Prince of Wales and Earl of Chester, thus for the first time uniting the six automatic and two traditional Scottish and English titles held by heirs-apparent to the two thrones. The ceremony of investiture was celebrated with a pageant "London's Love to Prince Henry", and a masque "Tethys' Festival" during which his mother gave a sword encrusted with diamonds, intended to represent justice.
