Further east, the kingdoms of Poland, Hungary, and Bohemia grew powerful. In Iberia, the Christian kingdoms continued to gain land from the Muslim kingdoms of the peninsula; Portugal concentrated on expanding overseas during the 15th century, while the other kingdoms were riven by difficulties over royal succession and other concerns. After losing the Hundred Years' War, England went on to suffer a long civil war known as the Wars of the Roses, which lasted into the 1490s and only ended when Henry Tudor (r. 14851509 as Henry VII) became king and consolidated power with his victory over Richard III (r. 148385) at Bosworth in 1485. In Scandinavia, Margaret I of Denmark (r. in Denmark 13871412) consolidated Norway, Denmark, and Sweden in the Union of Kalmar, which continued until 1523.
