List of Isselmere-Nielander monarchs

The House of Glaines-Oldmarch, or more precisely the House of Caitwuil-Houmbertis-Sigurdsson-Alvarsson, is the current Royal Family of Isselmere-Nieland. The present dynasty acceded to the throne in 1562, although the House of Glaines extends back to 1349. The House of Oldmarch is the cadet branch of the ancient royal house of Nieland, the House of Brýrláð, dating back to the twelfth-century.

Between 1653 and 1899, this dynasty was known as the House of Glaines-Oldmarch-Sifborg, but -Sifborg was dropped since the loss of the principality of Gudrof. The throne of that now sovereign state is held by the cadet branch of Glaines-Oldmarch.

Line of succession

The earliest monarchs of what is now Isselmere-Nieland were selected from a small number of noble families. In 1038, the Kingdom of Isselmere adopted primogeniture, formalised by the accession of Ethling (r. 1063–1085) to the throne. Primogeniture was not recognised in law until the birth of Berthuis I the Ravager in 1069. The Constitution Act, 1986 introduced cognatic primogeniture.

The line of succession is based upon four statutes — the Charter of Inheritance, 1013, the Articles of Succession, 1349, the Act of Settlement, 1557, and the Act of Consolidation, 1562 — as well as the Constitution Act, 1986. The Constitution Act established cognatic primogeniture as the means of dynastic succession.

The first in line to the throne is the Crown Princess and Duchess of Glaines, the latter title stemming from the reign of Alfred I (r. 1349–1372). Since 1562, the Heir Apparent is the Duke of Oldmarch as well. The Constitution Act (1986) has subsequently appended the title of Prince of Anguist.

Next in line is the Duke of Detmere, or Duke of Detmere should the second in line to the throne not be an offspring of the reigning monarch. The third in line of succession is the Duke of Daurmont. The eldest sibling of the reigning monarch is the Duke of Huise whilst the second sibling is known as the Duke of Angforth.

The Lords High Commissioners of Isselmere and Nieland are known as the Marchioness of Glaines and the Marquess of Oldmarch, respectively, symbolising their stewardship over the two lands.

The present line of succession is listed below:
