Franco-Hungarian alliance in 1528

[2] In 1526, Francis I again started to look for allies in Central Europe, this time by turning his attention to Hungary.

[2] In 1528, John Zápolya was very vulnerable since he had been defeated by Ferdinand of Austria, his rival claimant to the throne of Hungary, at the Battle of Tarcal in August 1527.

[1] Besides the French alliance, Zapolya chose to become a vassal to the Ottoman Empire in February 1528 through the negotiations of Jerome Laski.

[1][4] Rincon went to Istanbul to bring the document,[5] which triggered the development of relations between France and the Ottoman Empire.

In exchange, Zapolya agreed to continue the fight against Ferdinand of Austria and to provide Hungarian troops to Francis in Italy.
