Hungary - 1542-82 AD -Silver Denar - Louis I -  5 March 1326 – 10 September 1382), was King of Hungary and Croatia from 1342 and King of Poland from 1370 until his death in 1382. He was the first child of Charles I of Hungary and his wife, Elizabeth of Poland, to survive infancy. A 1338 treaty between his father and Casimir III of Poland, Louis's maternal uncle, confirmed Louis's right to inherit the Kingdom of Poland if his uncle died without a son. In exchange, Louis was obliged to assist his uncle in reoccupying the lands that Poland had lost in previous decades. He bore the title Duke of Transylvania between 1339 and 1342 but did not administer the province. 
 
Royal charters referred to military actions in Lodomeria and Wallachia in the first half of 1382, but no further information of those wars was preserved.[254] Louis, whose health was quickly deteriorating, invited the representatives of the Polish prelates and lords for a meeting in Zólyom (now Zvolen in Slovakia).[255] Upon his demand, the Poles swore loyalty to his daughter, Mary, and her fiancé, Sigismund of Luxemburg, on 25 July 1382.[255] Louis died in Nagyszombat (now Trnava in Slovakia) in the night on 10 or 11 September 1382.He was buried in the Székesfehérvár Cathedral in a chapel that had been built upon his orders.
