Source-derived summary

Mariana Victoria of Portugal (or of Braganza; Portuguese: Mariana Vitória; pronounced [mɐɾiˈɐnɐ]; full name: Mariana Vitória Josefa Francisca Xavier de Paula Antonieta Joana Domingas Gabriela de Bragança; Portuguese: [mɐˈɾiɐ ˈɐnɐ viˈtɔɾiɐ ʒuˈzɛfɐ]; 15 December 1768 – 2 November 1788) was a Portuguese Infanta (princess), the eldest daughter of Queen Maria I of Portugal and her king-consort, Infante Pedro of Portugal.

Biography

Mariana Victoria was born at the Royal Palace of Queluz, near Lisbon, on 16 December 1768. She was named after her maternal grandmother, Mariana Victoria of Spain, a daughter of Philip V of Spain.

Her grandmother Mariana went to Spain in 1777 to discuss an alliance with her brother Charles III of Spain. While there, she helped to arrange the marriage of Mariana Victoria and the Spanish king's younger son, Infante Gabriel. They married by proxy on 12 April 1785 at the Ducal Palace of Vila Viçosa. The couple met for the first time at the Royal Palace of Aranjuez on 23 May and had another nuptial ceremony.

The royal couple had three children, two of whom died in infancy. At the birth of their youngest child, Infante Carlos, Mariana and her husband were residing at Gabriel's private residence, the Casita del Infante at El Escorial. Mariana developed a fever following the birth, and red spots soon appeared on her skin.

Editorial summary

This brief starts where responsible research should: with the source description of “Infanta Mariana Vitória of Braganza” as portuguese Royal (1768-1788). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1768, 1788, 1777, 1785—that can be checked directly. The authority record carries competing date values—1768-10-15, 1768-12-15—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where Infanta, Mariana and Vitória can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as portuguese Royal (1768-1788). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
