What contributed to Columbus mismanagement of his colonies and later sea expeditions?

Columbus's mismanagement of his colonies and later sea expeditions stemmed from several factors, including his authoritarian leadership style, which alienated both his crew and the indigenous peoples. His lack of experience in governance led to conflicts and poor relations with settlers, while his fixation on gold and riches blinded him to the need for sustainable practices. Additionally, his reliance on a small, loyal base of supporters often resulted in the neglect of broader community needs and dissent. This combination of personal ambition and poor administrative skills ultimately hindered the success of his endeavors.
