A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colours and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events. The burning or destruction of a national flag is a greatly symbolic act.
The national flag of Sweden consists of a yellow or gold Nordic cross on a field of light blue. The Nordic cross design traditionally represents Christianity. The design and colours of the Swedish flag are believed to have been inspired by the present coat of arms of Sweden of 1442, which is blue divided quarterly by a cross pattée of gold. Blue and yellow have been used as Swedish colours at least since Magnus III's royal coat of arms of 1275.
The Flag of Finland, also called siniristilippu, dates from the beginning of the 20th century. On a white background, it features a blue Nordic cross, which represents Christianity.
The State Flag of the Union of Soviet Socialist Republics, or simply the Soviet flag, was a red banner with two communist symbols displayed in the canton: a gold hammer and sickle topped off by a red five-point star bordered in gold. The flag's design and symbolism are derived from several sources, but emerged during the Russian Revolution. It has also come to serve as the standard symbol representing communism as a whole, recognized as such in international circles, even after the dissolution of the Soviet Union in 1991.
The national flag of Poland consists of two horizontal stripes of equal width, the upper one white and the lower one red. The two colours are defined in the Polish constitution as the national colours. A variant of the flag with the national coat of arms in the middle of the white fess is legally reserved for official use abroad and at sea. A similar flag with the addition of a white eagle is used as the naval ensign of Poland.
The national flag of Switzerland displays a white cross in the centre of a square red field. The white cross is known as the Swiss cross or the federal cross. Its arms are equilateral, and their ratio of length to width is 7:6. The size of the cross in relation to the field was set in 2017 as 5:8. Alongside the flag of Vatican City, the Swiss flag is one of only two square national flags in the world.

The flag of Portugal is the national flag of the Portuguese Republic. It is a rectangular bicolour with a field divided into green on the hoist, and red on the fly. The lesser version of the national coat of arms of Portugal is centered over the colour boundary at equal distance from the upper and lower edges. Its presentation was done on 1 December 1910, after the downfall of the constitutional monarchy on 5 October 1910. However, it was only on 30 June 1911, that the official decree approving this flag as the official flag was published. This new national flag for the First Portuguese Republic, was selected by a special commission whose members included Columbano Bordalo Pinheiro, João Chagas and Abel Botelho. The conjugation of the new field color, especially the use of green, was not traditional in the Portuguese national flag's composition and represented a radical republican-inspired change that broke the bond with the former monarchical flag. Since a failed republican insurrection on 31 January 1891, red and green had been established as the colours of the Portuguese Republican Party and its associated movements, whose political prominence kept growing until it reached a culmination period following the Republican revolution of 5 October 1910. In the ensuing decades, these colours were popularly propagandised as representing the hope of the nation (green) and the blood of those who died defending it (red), to endow them with a more patriotic and dignified, therefore less political, sentiment.
The national flag of Lithuania consists of a horizontal tricolour of yellow, green, and red. It was adopted on 25 April 1918 during Lithuania's first period of independence from 1918 to 1940, which ceased with the occupation first by the Soviet Union, and then by Nazi Germany (1941–1944). During the post-World War II Soviet occupation, from 1945 until 1988, the Soviet Lithuanian flag consisted first of a generic red Soviet flag with the name of the republic, in 1953 that was changed to the red flag with white and green bands at the bottom.
The national flag of Spain, as it is defined in the Constitution of 1978, consists of three horizontal stripes: red, yellow and red, the yellow stripe being twice the height of each red stripe. Traditionally, the middle stripe was defined by the more archaic term of gualda, and hence the popular name la Rojigualda (red-weld).
The national flag of Ukraine consists of equally sized horizontal bands of blue and yellow.
In military organizations, the practice of carrying colours, standards, flags, or guidons, both to act as a rallying point for troops and to mark the location of the commander, is thought to have originated in Ancient Egypt some 5,000 years ago. The Roman Empire also made battle standards reading SPQR a part of their vast armies. It was formalized in the armies of Europe in the High Middle Ages, with standards being emblazoned with the commander's coat of arms.
The flag of Bohemia is a historic flag, which now forms part of the design in the modern flag of the Czech Republic. The flag, a horizontal bicolour, was based on the colours of the former monarchs of Bohemia.
The Coat of arms of the Republic of Latvia was officially adopted by the Constitutional Assembly of Latvia on 15 June 1921, and entered official use starting on 19 August 1921. It was created using new national symbols, as well as elements of the coats of arms of Polish and Swedish Livonia and of the Duchy of Courland and Semigallia. Thus, the coat of arms combines symbols of Latvian national statehood, as well as symbols of its historical regions. The Latvian national coat of arms was designed by Latvian artists Vilhelms Krūmiņš and Rihards Zariņš.
