Guernsey and the other Channel Islands represent the last remnants of the medieval Dukedom of Normandy, which held sway in both France and England. The islands were the only British soil occupied by German troops in World War II. The Bailiwick of Guernsey is a British crown dependency but is not part of the UK or of the EU. However, the UK Government is constitutionally responsible for its defence and international representation. The Bailiwick of Guernsey consists of the main island of Guernsey and a number of smaller islands including Alderney, Sark, Herm, Jethou, Brecqhou, and Lihou.
The climate is temperate with mild winters and cool summers and about 50% of days are overcast. The terrain is mostly flat with low hills in the southwest.
Financial services accounted for about 21% of employment and about 32% of total income in 2016 in this tiny, prosperous Channel Island economy. Construction, manufacturing, and horticulture, mainly tomatoes and cut flowers, have been declining. Financial services, professional services, tourism, retail, and the public sector have been growing. Light tax and death duties make Guernsey a popular offshore financial centre.
