Alonso Quijano is the personal name of the famous fictional hidalgo (lowest nobility caste) who is better known as Don Quijote, a name he invents after either falling into or feigning insanity.

Alonso Quijano was a humble man from La Mancha, Spain. He was so poor that he had to sell his books to buy food. One day, he read so much about chivalry that he became insane and decided to become a knight himself. He called himself Don Quixote and set out on a journey to right all the wrongs in the world. Along the way, he met his squire, Sancho Panza. Sancho was a simple man who was loyal to Don Quixote, even though he thought his master was crazy. Don Quixote and Sancho had many adventures together, including fighting windmills, battling giants, and rescuing damsels in distress. Don Quixote was a kind and brave man, but he was also very foolish. He often got himself into trouble because he was too trusting and believed everything he read in his books. However, he was also a very lovable character, and his adventures have been enjoyed by people all over the world for centuries.
