James I of Scotland was released from English custody on March 28, 1424 after 18 years of captivity, following the Treaty of Durham, returning to Scotland to claim his throne with his wife, Joan Beaufort, a cousin of the English King in England. He was crowned at Scone on May 21, 1424.
He faced high ransom costs and resentment from nobles, which coupled with his harsh centralized rule led to his assassination on February 21, 1437. Queen Joan had managed to escape the attack and successfully protected her son, James II who was six years old and went on to succeed James I, under a regency council established by Joan during his minority. James II was crowned at Holyrood Abbey. The assassins, led by James I's uncle Walter Stewart, Earl of Atholl, were executed after their failed attempt to seize power.
Scotland entered a period of power struggles between powerful nobles, Despite the chaos taking place during his minority, James II later continued his father’s work, strengthening royal authority and tackling powerful, rebellious families.
