John Wycliffe was a 14th-century English theologian and scholar known for his role in the early movement for church reform. He is best remembered for translating the Bible into English, making it more accessible to the common people. His work challenged the authority of the Roman Catholic Church and emphasized the importance of scripture. Wycliffe's ideas laid the groundwork for later reformers, including Martin Luther. He also advocated for the separation of church and state and criticized the wealth and corruption within the church. His followers, known as the Lollards, continued to promote his teachings after his death.
