According to the British orientalist, Lord Kinross, Bayezid was distinguished by haste, impulsivity, unpredictability and imprudence.
He cared little for state affairs, which he entrusted to his governors.
As Kinross writes, between campaigns Bayezid was often engaged in pleasures: gluttony, drunkenness and debauchery.
The courtyard of the Sultan was famous for its luxury and was comparable to the Byzantine court during its heyday.

At the same time, the Sultan was a talented commander.
In all 13 years of his reign, Bayezid suffered only one defeat, which eventually turned out to be fatal for him.
Despite his lust for earthly pleasures, Bayezid was a religious man and used to spend hours in his personal mosque in Bursa.
He also kept Islamic theologians in his circle.
