This thesis examines the profound political, religious, and economic transformations in England from the 14th to the 17th centuries and their impact on the evolution of Early Modern English. The study highlights how the Hundred Years' War and subsequent Wars of the Roses fostered a search for national identity, reflected in the expanding English vocabulary. It explores the religious upheavals triggered by Henry VIII’s break from the Roman Catholic Church, Mary I’s attempt to restore Catholicism, and Elizabeth I’s reaffirmation of Protestantism, which stabilized the religious landscape. Additionally, the thesis discusses how Elizabeth I’s victory over Spain and the subsequent rise in global trade, driven by trading companies, introduced numerous foreign words into English. The Elizabethan era, marked by the English Renaissance and the contributions of William Shakespeare, is shown to have significantly enriched the English lexicon. Overall, this study underscores how England's evolving national identity, religious and political shifts, and cultural developments were deeply intertwined with the growth and transformation of Early Modern English.
