Butterflies on Buda
Union of Poland and Hungary
On Buda a butterfly moved differently on how it flapped its wings.
On 1350, Stephen Uroš V and Elisabeth of Bosnia are betrothed despite the protests of Elisabeth of Poland, she was converted to Orthodoxy and married Stephen on 1361.
By 1355, the Piast King Casimir III's second marriage, to Adelaide of Hesse, was failing. His only legitimate children, born of his marriage to Aldona of Lithuania, were his two daughters, Duchess Elizabeth of Pomerania and Electress Cunigunde of Brandenburg. Elizabeth and Cunigunde both aspired to the crown; the former in the name of her four-year-old son, Casimir, and the latter for her husband, Elector Louis II. Other candidates were the surviving Piasts, Casimir III's distant agnates: Duke Vladislaus of Gniewkowo and Duke Siemowit III of Masovia. However, the King had arranged to be succeeded, should he himself have no legitimate sons, by either of his sister Elizabeth's sons, King Louis I of Hungary or Duke John of Slavonia.
On 1362, Elisabeth of Pomerania is married to Louis of Hungary due to the persuation of Casimir III to Boguslaw of Pomerania in order for the succession of Louis I of Hungary,the son of Charles Robert of Hungary to be more legitimate and to solidify the alliance between Pomerania, Hungary and Poland, the marriage of Elisabeth of Pomerania to Louis I of Hungary which would later produce healthy sons which meant a stronger Anjou Dynasty on Poland, the two were given dispensation by the Pope.

-Louis of Hungary b. 1366
-Stephen of Hungary b. 1367
Casimir III, Louis of Hungary and Lietpold of Habsburg would start to campaign to regain Silesia on 1369 causing the Dukes of Silesia break from Bohemian suzerainty and pass to Polish suzerainty and the Duchy of Wroclaw is annexed to Poland completely, the war between Bohemia and Poland ended on 1372 and the loses were recognized by Charles V.
Elisabeth of Pomerania and Louis would succeed in Poland on 1380 on the death of Casimir III but her brother Casimir IV of Pomerania predeceased her so there was no opposition on their rise on the throne of Poland. Louis I of Hungary became known as Louis I of Poland and Hungary and also Elisabeth of Pomerania is crowned as his consort, she groomed her son, Louis of Hungary as the King of Poland and Hungary while John of Hungary would be the successor to the claim to the throne of Naples. Elisabeth of Pomerania arranged the marriage of Stephen of Hungary to Valentina Visconti, the daughter of Gian Galeazzo Visconti in order to strengthen the ties of Milan to Hungary and also she arranged the marriage of her daughter, Jadwiga to Richard II of England, the marriage of Richard II and Jadwiga meant the recognition of the union of Poland and Hungary to the Western World, since Louis I of Hungary became King of Poland and Hungary the union became almost permanent.
Note:
I like a union of Poland and Hungary with Silesia which means that the union between Poland and Hungary would be strengthened.
