Henry IV

Henry IV refers to two notable kings in history: Henry IV of England (1367-1413) and Henry IV of France (1553-1610). The English Henry IV was the first king from the Lancaster line; he seized the throne from Richard II, leading to a period marked by civil strife known as the Wars of the Roses. The French Henry IV, known for his efforts to unify and stabilize France after religious wars, famously converted to Catholicism, saying "Paris is worth a mass." Both kings are significant for their lasting impacts on their respective nations' histories.
