and this Croatian source (longer) as well as this Croatian source (shorter)
Please note: This is my own poor translation from the Croatian source that uses old Croatian that is difficult for me to translate. It is good enough to get the essence of what he said but not god enough for academic use. I can't find a copy in English anywhere.
After the Ottomans learned of the death of
Ferdinand they asked Maximilian if he will pay the Porte the tribute that his
father had agreed to and owed and to announce if they are willing to live in
peace with the sultan under the terms his father had agreed to. In such an
important issue Maximilian can't decide on his own. Maximilian calls together
his representatives and advisors and
asks them what should be done about the peace of 1562 and the annual tribute of
30,000 ducats.
