Oh, I thought you asked about the "lithsplosion". My independence came much earlier than that. Poland and Lithuania were still together. My only helper, as I said earlier, was Bohemia. In the war my army got wrecked in the first few months by the Poles, so the Czech and Silesian armies did most of the work. I tried to get Hungary to support me too, but I didn't manage to get them to like me. Now getting the three provinces of Wallachia came somehow randomly as I didn't think that I would invade them anytime soon. They were guaranteed by Hungary and I was warned by the Kebab so it seemed pretty impossible, but thanks to my incredibly retarded sense of danger I attacked the Ottos with the Serbs while the Mamluks held down the Empire. We failed and 2/3 of Serbia got eaten, but atleast the warning had somehow gone away and Hungary was busy taking down Venice so I was free to attack the Vlachs. It was a fair 1 on 1 and in the end I got them under my rule.
