Yorkshire (abbreviated Yorks) formally known as the County of York is a historic county of Northern England and the largest in the United Kingdom Because of its great size in comparison with other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographic territory and cultural region The name is familiar and well understood across the United Kingdom and is in common use in the media and the military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and the East Riding of Yorkshire The emblem of Yorkshire is the White Rose of the English royal House of York, and the most commonly used flag representative of Yorkshire is the white rose on a blue field which, after nearly fifty years of use, was recognised by the Flag Institute on 29 July 2008 https://en.wikipedia.org/wiki/Yorkshire
