At that time, Spanish kingship encouraged nobles to establish world hegemony with knight honor and pride, and knight literature advocated loyalty to the monarch and protection of education, which just met their needs. They tried to resist the development and influence of humanistic literature with the help of knight literature. Cervantes hated this kind of mediocre and inferior knight literature, so he deliberately imitated the writing style of knight legend, shaped the characters of Don Quixote, exposed the absurdity and harm of knight literature through the absurd behavior and ridiculous experience of the protagonist, and mocked the knight ideal and knight system to the fullest.
