Sigismund, Holy Roman Emperor

Sigismund of Luxembourg (15 February 1368 – 9 December 1437) was Holy Roman Emperor from 1433 until he died in 1437. He was the son of Charles IV, Holy Roman Emperor and Elizabeth of Pomerania. Sigismund married Mary, Queen of Hungary in 1385 and became King of Hungary and Croatia (jure uxoris). After Mary died in 1395, he ruled Hungary alone.

Sigismund held many important titles. He was elected King of Germany (King of the Romans) in 1410 and became King of Bohemia in 1419. He was also a prince-elector of Brandenburg at different times. Sigismund was the last male member of the House of Luxembourg.

In 1396, Sigismund led the Crusade of Nicopolis but was defeated by the Ottoman Empire. He created the Order of the Dragon to fight against the Turks. Sigismund played a key role in the Council of Constance (1414–1418), which ended the Papal Schism. Later, this led to the Hussite Wars. In 1433, he was crowned Holy Roman Emperor and ruled until he died in 1437.

Historians note that Sigismund had big plans to reform the empire and the Church, but faced many difficulties. Later, the Habsburgs, especially Maximilian I, continued these reforms. Interest in Sigismund's life and time has grown, especially in East-Central Europe, as people recognize the challenges he faced.

Biography

Sigismund was born in Nuremberg or Prague. He was the son of Charles IV, Holy Roman Emperor, and his fourth wife, Elizabeth of Pomerania. From a young age, he was called the "ginger fox" because of his red hair.

Sigismund was promised to marry Mary, the daughter of King Louis the Great of Hungary and Poland, when he was just six years old. After his father died, he became Margrave of Brandenburg and was sent to live in Hungary. There, he learned the Hungarian language and customs and grew to love the country.

In 1385, Sigismund married Mary, and he was crowned King of Hungary in 1387. Some Hungarian nobles did not support him, so he had to work hard to keep his position. He also led soldiers against the Turks but lost a battle at the Battle of Nicopolis.

Later, Sigismund became King of Germany and King of Bohemia. He worked to make peace and form alliances across Europe, including with England and France. In his later years, he faced problems in Bohemia from the Hussites. Sigismund was crowned Holy Roman Emperor in 1433 and died in 1437.

Family and issue

Sigismund married two times and had only one child who lived. His first wife, Mary of Hungary, lost their baby during a riding accident. Sadly, both mother and child passed away. Later, Sigismund married Barbara of Celje, and they had one daughter, Elisabeth of Luxembourg, who grew up to be a queen.

Sigismund was very connected to Hungary. He spoke the language, wore Hungarian-style clothes, and even grew a beard like people in Hungary did. He spent a lot of money rebuilding important castles in Hungary.
