Franco closes the Gibraltar frontier (1969)
Spanish dictator Francisco Franco sealed the border with Gibraltar to pressure Britain over sovereignty. Families were split and the crossing stayed shut for years. The gate did not fully reopen until 1985.
Gibraltar was cut off by land for 16 years, forcing it to rely on sea and air links.
Spain fully reopened the frontier in 1985 as a condition of joining the European Community.
It shows how tightly Gibraltar's open border has been tied to Spain's place in Europe. This treaty reverses that history by folding Gibraltar into Schengen.
