How is humanism related to the renaissance?

Renaissance humanism was a response to the utilitarian approach and what came to be depicted as the "narrow pedantry" associated with medieval scholasticism.[2] Humanists sought to create a citizenry able to speak and write with eloquence and clarity and thus capable of engaging in the civic life of their communities and persuading others to virtuous and prudent actions. This was to be accomplished through the study of the studia humanitatis, today known as the humanities: grammar, rhetoric, history, poetry, and moral philosophy.
