 Szczerbiec, together with other crown jewels, was removed from the Wawel Hill on several occasions during that period. After his Polish coronation in 1370, King Louis I of Hungary took the crown jewels with him to Buda; his successor on the Hungarian throne, Emperor Sigismund, rendered them to Poland in 1412. On two occasions, in mid-17th and early 18th centuries, they were evacuated across Poland's southern border to protect them from invading Swedish armies. In 1733, during the War of the Polish Succession, supporters of King Stanislaus I concealed the jewels in a Warsaw church for three years to prevent Augustus III from using them in his coronation. In 1764, they were sent to Warsaw again, to be used in a coronation for the last time – that of Stanislaus Augustus Poniatowski. They were returned to Kraków afterwards.
