Ibrahim was a relatively weak leader. He was interested in governing the empire and extending and securing its borders, but he had an unstable character and he lead a life in excesses. He was also strongly influenced by the women of his harem and his viziers.
In order to cover his luxurious life style, he imposed heavy taxes, which lead to discontent among both the average person and the elite in the society. This was the main reason why an unusual union between the Janissaries and the ulama had him removed from power, and executed.
