The Gaplan monarchy is a largely ceremonial program which preserves Gapla’s culture, history, and tradition, and is an important source of state funding. The current monarch is Wyatt, Prince of the Danubias, who acceded to the throne first on 28 February 2019 and again on 20 August 2023, after taking a brief leave in 2023.

Gapla’s monarchy consists of one Prince or Princess of the Danubias, also known as the Sovereign Prince or Princess, who also holds the title of the Prince or Princess of Gaplastovia. In the case that the Prince or Princess of Gaplastovia is unable to perform the duties of the monarch, the line of succession is used to determine the holder of the title. Current Presidents and Deputy Presidents of Gapla are not eligible for the position of monarch, to uphold the independence of the monarchy and the government.

Gapla’s two states (Gaplastovia and Cristus) have a hereditary monarch with the rank of Prince or Princess, but are distinguished from others of the same rank. Each of Gapla’s three other municipalities (other than New Gaplastovia and Cristaria, which are state capitals) also have a hereditary monarch with the rank of Prince or Princess.

Other than His Majesty’s Title Service (see the section below), the Prince of the Danubias has the power to bestow titles for exceptional contributions to the country, although this practice is limited as the more common option is to bestow one of Gapla’s several awards and honors. Titles of Duke or Duchess have been awarded for historical reasons, and titles of lower rank have been awarded for other contributions to Gapla.
