Lajos I's resume.
1370, the Polish pianist dynasty lost its heir, and Lajos I entered Poland through the agreement of the dynasty nobles (the treaty between his father Charles I and Polish king Kasimir III). 1374, he granted the so-called Kosice privilege to the small aristocrats in Poland. After 1378, the third Hungarian-Venetian War broke out and Dalmatia was all taken. During the reign of Lajos I, the national strength of the Hungarian Kingdom reached its peak in the Middle Ages.
