I want to know the answer to the following question:
Who was appointed regent-governor of the Kingdom of Hungary in 1446?
All the background I'm provided with is that "After the tragic death of the young king Vladislaus I of Hungary during the Battle of Varna in 1444 against the Ottomans, the Kingdom was placed in the hands of count John Hunyadi, who became Hungary's regent-governor (1446–1453).". Is that enough to answer the question?
Answer: yes
