Overview

Serene Highness is a formal style of address historically applied to some princes and other members of high nobility. In English it commonly appears as "His Serene Highness" (HSH) or "Her Serene Highness." The style indicates a rank of dignity used in diplomatic and court protocol and is generally placed below Royal Highness and Imperial Highness in traditional precedence.

Usage and characteristics

The form is most often associated with sovereign or formerly sovereign princely families. It may be borne by a reigning prince, his immediate family, or by members of dynasties that once held independent territory. Typical features include use in formal introductions, written correspondence, and official proclamations. Variations in local languages exist, and abbreviation such as HSH is common in English-language documents.

History and development

Throughout the early modern and modern periods of Europe, numerous small states and principalities adopted distinctive styles to mark their rulers' status. The style has appeared among Italian and German princely houses and in other parts of Europe. Over time, as states merged, were mediatised, or absorbed into larger monarchies, the use of the style became more limited and largely ceremonial.

Contemporary examples and holders

Today the style survives in official use by a few sovereign dynasties. The reigning families of Monaco and Liechtenstein are commonly cited as current examples that use Serene Highness in formal settings. In addition, some non-sovereign families and descendants of former principalities continue to employ the style by tradition or heraldic claim; historians and heraldists sometimes debate particular cases and origins.

Notable distinctions and protocol

Key points to note about the style include:

  • Rank: It is lower than royal and imperial styles but higher than many ordinary noble forms.
  • Form: Usually appears with "His/Her" before the phrase and is followed by the holder's substantive title.
  • Variation: Local languages and historic usages create different equivalents, sometimes leading to ambiguous translations.
