The ShireThe Shire - The land where the hobbits settled.  It became vacant after the northern kingdom broke up.

 

"Fifty leagues it stretched from the Far Downs to the Brandywine Bridge, and fifty from the northern moors to the marshes in the south.  The Hobbits named it the Shire, as the region of the authority of their Thain, and a distinct and well-ordered business; and there in that pleasant corner little corner of the world they plied their well-ordered business of living, and they headed less and less the world outside where dark things moved, until they came to think that peace and plenty were the rule in Middle-earth and the right of all sensible folk." ~The Fellowship of the Ring (Prologue)
