The Wars of the Roses (1455-1487 CE) was a dynastic conflict where the nobility and monarchs of England intermittently battled for supremacy over a period of four decades. Besides the obvious consequences of Lancastrian and Yorkist kings swapping thrones several times and the establishment of the House of Tudor at the end of it all, the wars killed half the lords of the 60 noble families of England, established a much more violent political environment, and saw first a boost to the power of the nobility and then a swing back in the favour of the Crown. Finally, the wars have inspired historians and writers forever after, whether it be Tudor propagandists, William Shakespeare, or the creators of such television shows as Game of Thrones.
