What misappropriation of the reward for the first sighting of land did Columbus do?

Columbus misappropriated the reward for the first sighting of land by not acknowledging the contributions of Rodrigo de Triana, a crew member who first spotted land on October 12, 1492. Instead, Columbus claimed the reward for himself, as he had already declared that he had sighted land earlier that day. This act not only denied de Triana his due recognition but also set a precedent for Columbus's tendency to prioritize his own interests over those of his crew.
