Answer:
The question asks about the war that came before the feud between the two families. To answer this, we need to identify the specific families and the context of the feud. Without that information, it is difficult to provide a precise answer. However, I can give you a general example to illustrate how to determine the war that preceded a family feud.
Let's consider an example where the Montague and Capulet families are involved in a feud. In this case, the war that preceded their feud is the "War of the Roses." This war took place in England during the 15th century between two rival branches of the royal House of Plantagenet: the House of Lancaster (represented by a red rose) and the House of York (represented by a white rose).
The War of the Roses ended in 1485 with the victory of Henry Tudor, who became King Henry VII. After the war, the Tudor dynasty ruled England, and the feud between the Montague and Capulet families began, as depicted in William Shakespeare's play "Romeo and Juliet."
It's important to note that this is just an example, and the specific war that preceded a family feud will depend on the context and setting of the situation. By understanding the historical background and the specific families involved, you can determine the war that preceded the feud.
