What splits and reforms occurred in Christian Churches in the fifteenth thru nineteenth centuries?

Between the fifteenth and nineteenth centuries, significant splits and reforms occurred within Christian churches, notably the Protestant Reformation in the 16th century, initiated by figures like Martin Luther and John Calvin, which challenged the Catholic Church's practices and authority. This led to the formation of various Protestant denominations, including Lutheranism and Calvinism. In the 17th and 18th centuries, movements such as the Puritan and Methodist revivals further diversified Christianity. Additionally, the Catholic Church responded with the Counter-Reformation, culminating in the Council of Trent (1545-1563), which aimed to address corruption and reaffirm Catholic doctrine.
