The Prince of Youth (Latin: Princeps Iuventutis), or less frequently the Princess of Youth, is the main substantive title used by the heir apparent to the Latin throne. It has been vacant since the ascension of its last holder, Constantine XX on 3 November 2016.
The title originated in the 3rd century as an honorific title awarded to a presumptive emperor-designate, though was used sparingly. By the 7th century, the title was commonly affiliated with the eldest son of a reigning Emperor, following the practice of granting designated heirs unique titles, such as Destined to be Emperor (Imperator Destinatus). The title has two purposes: to serve as a title to name the heir apparent or heir presumptive, and as a specific title to determine place in the line of succession and role in government and earn incomes. The title has been held by women on X occasions, the first by Maria I Augusta from 979 until 1010; by Theodora I from 1240 until 1247; and most recently by Maria III from 1760 until 1763.
Titles and functions
The Prince of Youth as crown prince holds priority as the heir apparent or heir presumptive and is first in the line of succession to the Latin throne, holding the positions, titles, estates and incomes affiliated with that position. In addition, the Prince of Youth holds the following subsidiary titles:
- Duke of Alba
- Duke of Galata
Upon birth or succession, the eldest son of a reigning monarch is automatically invested as Prince of Youth and its subsidiary titles. After reaching the age of majority, a Prince of Youth must swear fidelity to the Monarch in order to be seated as a member of the Advisors of the Emperor. The Prince of Youth also serves as the president of numerous charities, including the Prince's Foundation, or Princess's Foundation in the event of a female title holder. More recently the Prince of Youth has also been invested as Duke of Adrianople, though it is not officially a subsidiary title.
