I'll try and give you two nordic examples.

Most norsemen-historians subscribe to the idea that in 12th century Europe in pagan areas you would of seen greater freedom for women. There's many pieces of evidence of nordic men behaving and treating women better then the majority did at the time, one of my favorites is skylitzes manuscript where you see two vikings hand over the possessions of a man to his sexual assault victim and leave him unburied- pretty progressive for their time and location.

However, Christianity was growing and with it women were loosing some of their rights but there were still areas where pagan women who had more rights than some women in the 1800s did in the same places. It's difficult to get exact examples for this time but if you compare the fact that a woman in Iceland in the 12th century would of been entitled to half her belongings, custody of her children depending on the age and also her dowry back if she needed to divorce her husband if he was abusing her - all this regardless of class ( Although to be fair there wasn't massive class differences - nothing close to what came later ). In 1800s Iceland a woman would be lucky if she got any of that, if she was even allowed to divorce her husband, and if her husband died then the district would seize the woman's property & children and she would be left alone, destitute and homeless. Consider this massive difference.

It should be said however that many of the sources we get about these viking era Icelandic women are from the Icelandic sagas - the sagas are semi fictional and it there is no agreed length to which you can trust them. Generally however they can be used as a source for social attitudes and practices at the time while the people in them maybe weren't real- many places and practices that the sagas reference are after all real. So women in the sagas whom were abused by their men could divorce them and get a lot of what they brought into the marriage back. In other cases they even got revenge on their husbands for beating them, take Hallgerd from Njals saga for example whom lets her husband die rather than helping him to string his bow because he hit her. Her last words to him? "“I shall now remind you of the slap you once gave me" and then she lets him die. So, women did have the option of divorcing their husband were he violent or if they were a bit feistier they might get revenge on him.

Now for the 14th century example. This example is actually 100 years after the 14th century but it's pretty famous, well documented and representative of Scandinavia of the time. Now that we're a little later in history it's easier to talk about specific people. Sofia Vasa is a good example of a woman who was abused by her husband and whose abuse was written about mostly because she was a member of the Swedish royal family (this is also relevant in relation to the punishment her husband got as not all common women would of been so lucky).

Her husband Magnus was not a nice type, he is said to have been a thief and violent with his wife and servants. He beat his wife Sofia so violently and he was so cruel to her that she never recovered. The royal chronicler wrote about her suffering saying that he showed her such "unlove spit and insults, that she because of that sorrow ended up with a weakmind" (likely a mental illness such as PTSD). Eventually her husband was exiled from the country by the current king Johan for wife beating , an unusually harsh punishment for the time. In her case she could not really do anything about her abuse, she suffered in public and it did not end till those who pitied her put a stop to it. She lived a tragic life afterwards and was permanently mentally scarred, her family wrote a lot about her suffering which is why we know so much. It's likely that there were other women in the aristocracy in her position whom were not so openly abused by their husbands, divorce for them was difficult at the time due to the laws but also social consequences within the christian circle.
