Because there was no clear heir to the throne anymore, the Scottish people decided to ask Edward I of England to choose their king. The strongest candidate was called Robert Bruce. Robert Bruce had castles all around the country, and had a private army. But Edward wanted to invade Scotland, so he chose the weaker candidate, who was John Balliol. He had the strongest claim to the throne, and became king on 30 November 1292. Robert Bruce decided to accept this decision (his grandson and namesake later took the throne as Robert I).
