Why is my one year old crying uncontrollably 😩

So today my daughter has been woken up by her naps twice. When I️ got home from work she was napping and started crying uncontrollably like if she was getting hurt or something and didn’t stop until I️ stood up and started rocking her and put her her favorite movie on. But even then she didn’t fully stop she was still fussing a little . And the same thing is happening now. I️ had to take her out of the room to calm her down and get entertained by the Christmas tree. I️ know she’s tired so I️ don’t know why she’s acting like this. It’s frustrating not knowing why she’s crying..she’s never done this before , I️ don’t think its teething. She was just crying and crying, on going for about 10-15 mins.
