https://en.wikipedia.org/wiki/Yolanda_of_Flanders
Yolanda of Flanders (Yolande de Hainault; 1175 – August 1219) ruled the Latin Empire 
in Constantinople for her son Philip of Namur from 1217 to 1219 after her husband 
Peter II of Courtenay was captured and imprisoned before he could reach 
Constantinople.[1]

Biography[edit]

Yolanda was the daughter of Baldwin V, Count of Hainault, and Countess Margaret I 
of Flanders. Two of her brothers, Baldwin I and then Henry, were emperors in 
Constantinople. After the death of the latter in 1216 there was a brief period without 
an emperor, before Peter was elected. Peter sent Yolanda to Constantinople while he 
fought the Despotate of Epirus, during which he was captured. Because his fate was 
unknown (although he was probably killed), Yolanda ruled as regent. She allied with 
the Bulgarians against the various Byzantine successor states, and was able to make 
peace with Theodore I Lascaris of the Empire of Nicaea, who married her daughter. 
However, she soon died, in 1219.

Family and legacy[edit]

Following Yolanda's death, her second son, Robert of Courtenay, became emperor 
because her oldest son, Philip, did not want the throne.[1] As Robert was still in 
France at the time, there was technically no emperor until he arrived in 1221.

Yolanda was, in her own right, Marchioness of Namur, which she inherited from her 
brother, Marquis Philip I, in 1212 and left to her eldest son, Marquis Philip II, when 
she went to Constantinople in 1216.

By Peter of Courtenay she had 10 children:
Philip (d. 1226), Marquis of Namur, who declined the offer of the crown of the Latin 
Empire
Robert of Courtenay (d. 1228), Latin Emperor
Henry (d. 1229), Marquis of Namur
Baldwin II of Constantinople (d. 1273)
Margaret, Marchioness of Namur, who married first Raoul d'Issoudun and then Henry 
count of Vianden
