That's interesting. I didn't know that. Was this recently?
There are in fact quite a few examples of Kings Consort, including recent ones:
-
Francis II of France and Lord Darnley
The first and second husbands of Mary, Queen of Scots were both accorded the styles of Kings Consort of Scotland. Francis II was a King Consort from
1558 to 1560, and Darnley was King Consort from
1565 to 1567.
-
Philip of Spain
I've discussed his position in a previous post.
-
Francis, Duke of Cadiz
Was King Consort to Isabella II of Spain from
1846 to 1868.
-
Philip IV of France
Apart from being King of France, he was also King Consort of Navarre as husband of Joan I of Navarre from
1284 to 1305.
-
Philip III of Navarre
King Consort of Joan II of Navarre from
1328 to 1343.
-
John II of Aragon
King of Aragon, as well as King Consort of Blanche I of Navarre from
1425 to 1479. Admittedly, after his wife's death, he became effectively a King Regnant of Navarre.
-
John III of Navarre
King Consort of Queen Catherine of Navarre from
1484 to 1516.
-
Antoine de Bourbon
King Consort of Jeanne III of Navarre from
1555 to 1562.
-
Ferdinand II of Aragon
King of Aragon as well as King Consort of Isabella I of Castile from
1475 to 1504.
-
David Soslan
King Consort of Queen Tamar of Georgia from
1189 to 1207.
-
Ghias ad-din
King Consort of Queen Rusudan of Georgia from
1223 to 1226 (when the Queen repudiated the marriage because of his re-conversion to Muslim religion)
-
Philip of Antioch
King Consort of Queen Isabella of Armenia from
1222 to 1224.
-
Hethum I of Armenia
King Consort of Queen Isabella of Armenia from
1226 to 1230s (he became Isabella's co-regnant monarch in 1230s, after their first child was born).
-
Louis of Cyprus
King Consort of Queen Charlotte of Cyprus from
1459 to 1464 (as well as titular King Consort of Jerusalem and Armenia).
There was also the case of
Portuguese Queens Regnant and their spouses. According to Portuguese laws, the consort of a Queen Regnant automatically became King when and if an issue was born to them. Generally, it is agreed that those Kings were Kings Consort and not Kings Regnant, although they did have numerals - something usually reserved for reigning Monarchs only. Two examples could be
Fernando II of Portugal(consort of Queen Maria II of Portugal from 1837 to 1853) and
Peter III of Portugal (consort of Maria I of Portugal from 1777 to 1786). The system was similar to the one used in Navarre where Kings Consort usually (but not always) were accorded numerals as well.
In addition, provisions for an
Emperor Consort was made in the Brazilian Constitution of 1823 (Article 120).
Back in 1554, though, and though it might have worked for the time, I don't think many people would like the reign of Bloody Mary to be repeated.
I've made a post on that immediately after yours. I'm not saying the scenario is likely, but it is not unprecedented for it happened both in England and Scotland, as well as quite a few other countries. Admittedly, in most cases, that was centuries ago.
