my mistake about baptism, I forgot about it.
I do appreciate it.
It is noble of you to admit a mistake which wasn`t so big, actually. If it is true, according to one historical presumption, that Mieszko was baptised in Regensburg instead of Polish towns of Poznań, Gniezno or Ostrów Legnicki, then, good Germans helped Poles to get baptised although bad Germans tried to prevent it. It was a fascinating game by Mieszko to play the former against the latter. I don`t have time to develop the topic, it was discussed in the Polish link I gave earlier.
Satisfied with your performance, I will answer the other part of your post (normally I try not to discuss anything with unregistered users because they are insincere tricksters.
=retroDog]and German leader (Otto 3?) coronated first polish official prince, those makeing Poland an official state
Nope. The first Polish king, Bolesław the Brave, was coronated in 1025, taking advantage of the political mess in Germany at the time. It was soon after Polish German war, so the relations were very antagonistic.After Henry's death in 1024, Bolesław I took advantage of the interregnum in Germany and crowned himself king in 1025, thus raising Poland to the rank of a kingdom before its neighbor Bohemia. He was the first Polish king (rex), his predecessors having been considered dukes (dux) by the Holy Roman Empire and the papacy. Bolesław I died not long after the coronation, due most likely to an illness.
The German Polish cooperation between Otto I and Bolesław took place earlier, in 1000. I will talk about it.
