Gibraltar is a British overseas territory located on the southern end of the Iberian Peninsula at the entrance of the Mediterranean. It is a peninsula of 6.843 square kilometres (2.642 sq mi) whose isthmus connects to the north with Spain. The Rock of Gibraltar is the major landmark of the region. At its foot is the densely populated city area, home to almost 30,000 Gibraltarians and other nationalities.

An Anglo-Dutch force captured Gibraltar in 1704 during the War of the Spanish Succession. The territory was subsequently ceded to Britain by Spain under the Treaty of Utrecht in 1713. It became an important base for the British Royal Navy. Today its economy is based largely on tourism, financial services and shipping.

The sovereignty of Gibraltar is a major point of contention in Anglo-Spanish relations as Spain asserts a claim to the territory and seeks its return. Gibraltarians resoundingly rejected proposals for Spanish sovereignty in referenda held in 1967 and 2002. Under its 2006 constitution Gibraltar governs its own affairs, though some powers, such as defence and foreign relations, remain the responsibility of the UK Government.

Panama, officially the Republic of Panama (Spanish: República de Panamá), is the southernmost country of Central America. Situated on the isthmus connecting North and South America, it is bordered by Costa Rica to the northwest, Colombia to the southeast, the Caribbean Sea to the north and the Pacific Ocean to the south. The capital is Panama City. Explored and settled by the Spanish in the 16th century, Panama broke with Spain in 1821 and joined a union of Nueva Granada, Ecuador, and Venezuela - named the Republic of Gran Colombia. When the latter dissolved in 1830, Panama remained part of Colombia. With US backing, Panama seceded from Colombia in 1903. The Panama Canal was built by the US Army Corps of Engineers between 1904 and 1914. In 1977, an agreement was signed for the complete transfer of the Canal from the US to Panama by the end of the century.

The current flag of the Republic of South Africa was adopted on 27 April 1994, at the beginning of the 1994 general election, to replace the flag that had been used since 1928. The new national flag, designed by State Herald Frederick Brownell, was chosen to represent the new democracy.

The flag has horizontal bands of red (on the top) and blue (on the bottom), of equal width, separated by a central green band which splits into a horizontal "Y" shape, the arms of which end at the corners of the hoist side (and follow the flag's diagonals). The Y embraces a black isosceles triangle from which the arms are separated by narrow yellow bands; the red and blue bands are separated from the green band and its arms by narrow white stripes. The stripes at the fly end are in the 5:1:3:1:5 ratio.

In blazons (a vexillological description using flag terminology), the South African flag is described as "per pall fesswise gules, sable and azure, a fesswise pall vert fimbriated argent, Or and argent."

Brazil flag

The national flag of Brazil (Portuguese: Bandeira do Brasil) is a blue disc depicting a starry sky spanned by a curved band inscribed with the national motto, within a yellow rhombus, on a green field. Brazil officially adopted this design for its national flag on November 19, 1889, replacing the flag of the second Empire of Brazil. The concept was the work of Raimundo Teixeira Mendes, with the collaboration of Miguel Lemos, Manuel Pereira Reis and Décio Villares.

The green field and the yellow rhombus from the previous imperial flag were preserved – the green and yellow colors representing the Braganza-Habsburg dynasty. A blue circle with 27 white five-pointed stars replaced the arms of the Empire of Brazil. The stars, whose position in the flag reflect the sky over Rio de Janeiro on November 15, 1889, represent the union's federated units – each star representing a specific state. The motto "Ordem e Progresso" ("Order and Progress") is inspired by Auguste Comte's motto of positivism: "L’amour pour principe et l’ordre pour base; le progrès pour but" ("Love as a principle and order as the basis; progress as the goal").
