Answer
The year 1031 marked a tumultuous time in Hungarian history when Vazul, the father of Béla I, faced imminent execution. This harsh fate was orchestrated by King Stephen I, Vazul's cousin, due to concerns regarding Vazul's potential claim to the throne. Despite escaping this ordeal, Vazul's sight was impaired as a result, effectively disqualifying him from future kingship according to the customs of the time.
