Scotland
In 1328, Edward III signed the Treaty of Northampton which declared Scottish independence under the rule of Robert the Bruce. Four years after Robert's death in 1329, England invaded Scotland yet again, looking to put the "Rightful King"—Edward Balliol, son of John Balliol—to the Scottish throne, starting the Second War of Independence. In the face of tough Scottish resistance, led by Sir Andrew Murray, attempts to secure Balliol on the throne failed. Edward III lost interest in Balliol after the outbreak of the Hundred Years' War with France. In 1341 David II, King Robert's son and heir, was able to return from temporary exile in France. Balliol finally resigned his empty claim to the throne to Edward in 1356, before retiring to Yorkshire, where he died in 1364.
