Page "Maria, Queen of Sicily" Paragraph 4

In 1392 Maria and the two Martins returned with a military force and defeated the opposing barons, ruling jointly until Maria's death in 1401.

At that time, Martin repudiated the Treaty of 1372 and ruled Sicily alone.

She also survived their only son, Peter ( 1398 – 1400 ).

The kingdom remained without a crown prince and it caused a succession crisis for Martin, who ruled by right of his wife.

According to the last will of Frederick III, he named his illegitimate son, William of Aragon, Count of Malta as heir presumptive in this case of the extinction of his daughter's line and although William died in c. 1380, he had a daughter, Joan of Aragon, wife of a Sicilain noble man, Pietro di Gioeni, but she must not have contested the claim of her aunt's husband since Martin continued to rule until his death.
