Yorkshire is a historic county in the northern part of England and the largest in the United Kingdom, and is the site of much of England's last unspoiled greenery. Due to its great size in comparison to other English counties, it has since been divided into different regions, but is still recognised as a geographical territory and cultural region. Yorkshire is known in popular culture for the dialect spoken there, which has a distinctive accent and many unique slang words. While speaking the same language, even people from other parts of England have difficulty understanding Yorkshire talk, and this culture shock has become a popular staple in British comedy.
In an alternate where the Great Black Deaths killed 80% of Europe's population in the 14th century, medieval culture stagnated. By the late 21st century, the English language was spoken only in England, and it was very different from the English spoken in the home timeline. Annette Klein believed that this version of English, of which she could only understand half the words, originated from the Yorkshire dialect.
Alistair Walsh encountered a number of Yorkshiremen in his service with the British Army, Jock among them. Their dialect was difficult for people from other parts of England to understand. Walsh, being Welsh, also had trouble understanding Yorkshire dialect, but could sympathise with being regarded as something of an oddity.
Though the Ice Age had abated millennia ago, it left a number of glaciers in northern Yorkshire that persisted into the 20th century.
The people of Yorkshire were shaped by cold winds and hard terrain the glaciers produced. The early humans who settled what became Yorkshire realized the value of taming the woolly mammoths that roamed the countryside, although this practice died out in the mid-20th century as the glaciers began melting.
Although Yorkshire was part of England, the influence of the Vikings was seen in the accent and vocabulary of the people.
