How did this county come to be?
History of Island County
The county's name reflects the fact that it is composed entirely of islands. It contains two large islands, Whidbey and Camano, and seven smaller islands (Baby, Ben Ure, Deception, Kalamut, Minor, Smith, and Strawberry). Island County was created out of Thurston County on December 22, 1852, by the legislature of Oregon Territory, and is the eighth-oldest county in Washington. It originally encompassed what are now Snohomish, Skagit, Whatcom, and San Juan Counties. Island County comprises the Oak Harbor, Washington Micropolitan Statistical Area, which is also included in the Seattle–Tacoma, WA Combined Statistical Area.
