After the fall of the great Roman Empire, a new era was born, the era of knights in shining love and great kings in castles of stone. Yet it was also a chaotic time, war and plague were a disease for Europe. Countries fought for land, resources, and, above all, God's attention. The world was young and so was the English language. Few writers wrote in English, the language of the people, because French and Latin were the languages ​​of the powerful elite. Yet a writer dared to speak against the feudal society into which he was born. Geoffrey Chaucer spent most of his life in the service of the crown, both as a soldier and as a clerk. Yet, through all these titles, Chaucer would forever be immortalized as Geoffrey Chaucer, the writer and satirist. The true goal of all satire is to point out the flaws in some aspect of society, while inspiring reforms on that same aspect in one way or another. In Chaucer's Canterbury Tales, Chaucer satirizes the corruption of the Catholic Church and its associates. Chaucer saw that hypocrisy was polluting the purity of the Church and expressed his disillusionment through the use of satire. Fearing no discommunication, Geoffrey Chaucer, the father of satire, dared to speak openly about the absolute corruption of the medieval Church. Medieval society centered on the flawed Catholic Church, where hypocrisy and corruption poisoned the purity of religion. When an individual spoke out against the Church's way of doing things, the Church simply retaliated. One example is that of Joan of Arc, a French farmer who became a soldier. The Church was outraged by his choices, performing acts reserved for men. Joan wore men's clothing and had short hair to avoid being the man in the middle of the paper in a time of great despair. Through the greatness of his actions, satirically highlighting the corruption in the Catholic Church, Chaucer established a reputation as one of the greatest writers in the English language. Without fear of reprisal from the Church, Chaucer continued to educate his audience, the English-speaking commoners of medieval Europe, who had long been exploited by the Church, becoming one of the greatest and earliest English satirists and the father of English satire.
