What happened in the year 1414?

In 1414, the Council of Constance convened, which was a significant ecumenical council of the Roman Catholic Church aimed at addressing various issues, including the Western Schism, where multiple claimants to the papacy existed. The council ultimately led to the deposition of the rival popes and the election of Pope Martin V, restoring a degree of unity to the church. Additionally, the council is notable for the condemnation and execution of the Czech reformer Jan Hus, who was a precursor to the Protestant Reformation.
