Gibraltar

parliamentary democracy (Parliament); self-governing overseas territory of the UK

Spain reluctantly ceded the strategically important Gibraltar to Great Britain in the 1713 Treaty of Utrecht, and the British garrison at Gibraltar was formally declared a colony in 1830. In a referendum held in 1967, Gibraltarians voted overwhelmingly to remain a British dependency. After the UK granted Gibraltar autonomy in 1969, Spain closed the border and severed all communication links.
