Precedence - Who Outranks Who?

[Tatiana Maria]

There are limited examples in the other European monarchies, primarily because they have fewer persons in line to the throne, but recent examples existed in Luxembourg and Monaco. Semi-Salic succession to the throne was in effect in Luxembourg until 2011, but the Grand Duke's siblings and children were cited in order of birth. Sons remain ahead of daughters in the line to the Monegasque throne, but Charlotte Casiraghi was cited ahead of her younger brother Pierre in royal communications even before Pierre's marriage (upon which he may have dropped out of the line of succession, as discussed here).

A less recent example: In the archives of the Belgian Parliament, Astrid is listed before Laurent even before she was given succession rights to the Belgian throne in 1991.

The UK seems to be alone in Europe in assigning younger brothers (the Dukes of York and Edinburgh, the Earl of Wessex) precedence ahead of their older sisters (the Princess Royal, Lady Louise Mountbatten-Windsor) even when the younger brother is not the heir to the throne.
