During the Peace of Turin in 1381, Zámbó personally received the annual tribute of 7,000 ducats which the Republic of Venice should pay to the crown of Hungary.
[2] He was promoted to Master of the treasury (Latin: magister tavarnicorum) in 1382, the same year Elizabeth's daughter Mary succeeded to the Hungarian throne.
Upon her return from Croatia-Dalmatia, Elizabeth exempted the Jews of Buda, Pressburg, Sopron, Nagyszombat, Székesfehérvár, and other cities from Zámbó's overlordship until he agreed to pay them out for the injuries inflicted upon them.
[4] In August 1384, Zámbó, along with Nicholas Szécsi and the House of Lackfi, renounced allegiance to Queen Elizabeth, who ruled in her daughter's name as regent, due to her intention to break Mary's engagement to Sigismund of Luxembourg and have her married to Louis of France.
However Zámbó was accused of having embezzled chamber's profit (lucrum camerae) by John Kanizsai, Archbishop of Esztergom, demanding 1,200 gold forints.
[7] Between around 1367 and 1383, Zámbó founded a Pauline monastery in Kisbaté (Gecseny), Tolna County, dedicated to Saint Ladislaus I of Hungary and Sigismund of Burgundy.
