Edward I vs Rupert of the Palatinate

Edward I led a military campaign that resulted in the conquest of Wales. After the death of Llywelyn ap Gruffudd, Edward built a ring of castles (including Caernarfon and Conwy) to control the region. The Statute of Rhuddlan in 1284 annexed Wales to England.

Edward I issued the Edict of Expulsion, ordering all Jews to leave England. The expulsion was motivated by financial and religious pressures. Jews were given until November 1 to depart, and their property was confiscated by the crown. The ban lasted until 1656.

Edward I summoned the Model Parliament, which included representatives of the commons (knights and burgesses) alongside nobles and clergy. This assembly set a precedent for the composition of the English Parliament. It was called to approve taxes for wars in Scotland and France.

Edward I invaded Scotland after the Scots refused to support his war in France. He captured Berwick and defeated the Scots at the Battle of Dunbar. Edward forced the submission of Scottish nobles and removed the Stone of Scone to Westminster Abbey.

The four Rhenish electors deposed Wenceslaus IV and elected Rupert of the Palatinate as King of the Romans. Rupert's election was contested by Wenceslaus and his supporters, leading to a divided empire. Rupert was never crowned Holy Roman Emperor by the Pope.

Rupert led an expedition to Italy to secure his coronation as Holy Roman Emperor and to support Pope Boniface IX against his rivals. The campaign was a failure; Rupert's army was defeated by the forces of Gian Galeazzo Visconti of Milan near Brescia. Rupert retreated to Germany without achieving his goals.

Rupert became embroiled in a conflict with Archbishop Johann II of Mainz over the election of a new bishop in the diocese of Paderborn. The dispute escalated into a military confrontation, with Rupert besieging the archbishop's castle. The conflict was eventually resolved through mediation, but it weakened Rupert's authority.
