I want to know the answer to the following question:
Where was the Mielnik Polish–Lithuanian union refromed?
All the background I'm provided with is that "On 23 October 1501, at Mielnik Polish–Lithuanian union was reformed at the Union of Mielnik (Polish: unia mielnicka, unia piotrkowsko-mielnicka).". Is that enough to answer the question?
Answer: yes
