in some realms, the women could reign... for exemple, in Scotland...
because if in France, only men could reign and until Philippe IV le Bel, if no sons, it was the husband's daugher who could be king (which created the 100 years war)
In other countries, such as "spanish" states, or "british" states, you could have a queen...
Maybe not in the 11th century, but around the XIIIth-XIVth...if I remember well
Nowadays, in Spain, Britain, Belgium a daughter if she is the eldest (Spain or Belgium) or without brothers (Britain) she can become queen by herself, with her husband who is a Consort.
