Edward I of Scotland. Brother to Robert the Bruce, and a campaigner during the First War for Scottish Independence, Bruce would return from Ireland in 1318, dejected, having had his campaign to unite Ireland behind his Kingship rejected and defeated by the Anglo-Irish lords. Bruce would narrowly avoid death through chance, and would retreat and eventually retire back to Scotland. In the Parliament of 1318, held in Fife, due to his brother lacking a male heir of his own body-despite having a grandson from his daughter Marjorie- Edward was confirmed as his heir, and as such was also formally reconfirmed as Earl of Carrick. Over the next few years, Edward would help his brother in solidifying Bruce control over Scotland defeating any who rose up against his brother, as well as the many small English incursions that occurred. His status as heir apparent was lessened when his brother's wife Elizabeth finally gave birth to twin boys, named David and John, thus pushing Edward down to third in line for the throne, via another act of Parliament in 1325. However, following John's death in 1327, Edward once more became second in line to the throne. Edward was a signatory of the Declaration of Arbroath as well as a witness to the Treaty of Edinburgh-Northampton. He was named regent for his nephew, King David, when his brother died, and as such played a large part in keeping Scotland under Bruce hands during the Second War of Scottish Independence. His relationship with his nephew would be cordial and at times tense, David would be desperate for an heir but his marriage to Joan of England would produce little success. David would eventually end up dying during The Battle of Neville's Cross in 1345, fought as part of the Hundred Years war, his death meant that Edward would ascend the throne in 1345 as Edward I, his reign short though it might've been would definitely be an interesting one.
