The Alexiad by Anna Comnena (sister of 4. Theodora), is a classic of medieval literature:

Of the Angeli, Norwich says:  “Of all the families that reigned over Byzantium, the Angeli were the worst.  Their supremacy was mercifully short — the three Angelus Emperors — Isaac II, Alexius III and Alexius IV — altogether reigned only nineteen years.  But each was disastrous, and together they were responsible for Constantinople’s greatest catastrophe until its final fall.”  Norwich is referring to the sack of Constantinople in 1204 by the Franks of the Fourth Crusade.  Constantinople finally fell to the Turks in 1453.

Of the wife of Louis III (The Blind), King of Provence & Italy (d. 5 June 928), AR8 (2004) names her as Anna, daughter of the Byzantine Emperor Leo VI.  Norwich (1997) has a chart showing Anna as Louis III’s wife, but Ostrogorsky (1969) and Treadgold (1997) are silent on the matter.


Alice (Dymoke) Skipwith descended from two kings of Jerusalem:

Fulk V, Count of Anjou, King of Jerusalem 1131-1143, d. 10 Nov 1144 in a hunting accident near Acre, bur. in the Church of the Holy Sepulchre; m. (1) Erembourg of Maine; grandparents of Henry II of England.  Fulk m. (2) Melisende de Rethel.  The royal tombs are in the Chapel of Adam.

Jean de Brienne, b. ca. 1168, d. 21 Mar 1237, King of Jerusalem 1210-1215, Latin Emperor of Constantinople 1228; m. (3) Berengaria of Leon; ancestors of Roger de Mortimer, 1st Earl of March (executed by Edward III), lover of Edward II’s queen Isabella of France. Mortimer’s daughter Catherine m. Thomas de Beauchamp, 11th Earl of Warwick.

Although Greek rule of some Byzantine territories didn’t end after the sack of Constantiniple, the imperial city was not retaken by the Greeks until 1261.  The Byzantine empire was steadlily encroached upon by Muslim forces until Constantinople fell to the Ottomans under Mehmet II on May 29, 1453.
