What was Jacques Cartier's biggest mistake?

Jacques Cartier's biggest mistake was underestimating the complexity of the indigenous relationships he encountered during his voyages to North America. He primarily sought to establish trade and claim land for France but often misinterpreted the intentions and social structures of the Native peoples, leading to conflicts and misunderstandings. His failure to foster genuine alliances limited the potential for successful colonization and trade. Ultimately, this lack of diplomatic engagement hindered his expeditions’ long-term success.
