Casablanca located in the central-western part of Morocco and bordering the Atlantic Ocean, is the largest city in Morocco. It is also the largest city in the Maghreb region, as well as one of the largest and most important cities in Africa, both economically and demographically.

Casablanca is Morocco's chief port and one of the largest financial centers on the continent. According to the 2014 population estimate, the city has a population of about 3.35 million in the urban area and over 6.8 million in the Casablanca-Settat region. Casablanca is considered the economic and business center of Morocco, although the national political capital is Rabat.

The leading Moroccan companies and international many corporations doing business in the country have their headquarters and main industrial facilities in Casablanca. Recent industrial statistics show Casablanca retains its historical position as the main industrial zone of the country. The Port of Casablanca is one of the largest artificial ports in the world, and the second largest port of North Africa, after Tanger-Med 40 km (25 mi) east of Tangier. Casablanca also hosts the primary naval base for the Royal Moroccan Navy.

Gibraltar  is a British Overseas Territory located at the southern tip of the Iberian Peninsula. It has an area of 6.7 km2 (2.6 sq mi) and is bordered to the north by Spain. The landscape is dominated by the Rock of Gibraltar at the foot of which is a densely populated town area, home to over 30,000 people, primarily Gibraltarians. It shares a maritime border with Morocco.

In 1704, Anglo-Dutch forces captured Gibraltar from Spain during the War of the Spanish Succession on behalf of the Habsburg claim to the Spanish throne. The territory was ceded to Great Britain in perpetuity under the Treaty of Utrechtin 1713. During World War II it was an important base for the Royal Navy as it controlled the entrance and exit to the Mediterranean Sea, which is only 8 miles (13 km) wide at this naval choke point. It remains strategically important, with half the world's seaborne trade passing through the strait. Today Gibraltar's economy is based largely on tourism, online gambling, financial services and cargo ship refuelling.

The sovereignty of Gibraltar is a point of contention in Anglo-Spanish relations because Spain asserts a claim to the territory. Gibraltarians rejected proposals for Spanish sovereignty in a 1967 referendum and, in a 2002 referendum, the idea of shared sovereignty was also rejected.
