The flags of the Confederate States of America have a history of three successive designs from 1861 to 1865. The flags were known as the "Stars and Bars", used from 1861 to 1863, the "Stainless Banner", used from 1863 to 1865, and the "Blood-Stained Banner", used in 1865 shortly before the Confederacy's dissolution. A rejected national flag design was also used as a battle flag by the Confederate Army and featured in the "Stainless Banner" and "Blood-Stained Banner" designs. Although this design was never a national flag, it is the most commonly recognized symbol of the Confederacy.

The Cross of Burgundy or the Cross of Saint Andrew, a saw-toothed (raguly) form of St. Andrew's cross, was first used in the 15th century as an emblem by the Valois Dukes of Burgundy, who ruled a large part of eastern France and the Low Countries as effectively an independent state. The Burgundian Low Countries were inherited by the Habsburgs, who adopted the flag at the extinction of the Valois ducal line and continued to use it as one of their many symbols up to the 18th century. With the Burgundian Habsburgs coming to power in Spain in the 16th century, the emblem served as a naval ensign of the Spanish Empire up to 1701, and up to 1843 as the land battle flag, acquiring a global impact throughout Europe and the Americas in the possessions of the Spanish crowns of Castile and Aragon. It is found nowadays in different continents and still appears on regimental colours, badges, shoulder patches and company guidons. The use of the emblem in a variety of contexts, in a number of European countries and in the Americas, reflects the historical extent of Burgundian, Habsburg, and Spanish territories.

It is one of three U.S. state flags to feature the words "In God We Trust", with the other two being those of Georgia and Mississippi.

Saint Patrick's Saltire or Saint Patrick's Cross is a red saltire on a white field. In heraldic language, it may be blazoned "argent, a saltire gules". The Saint Patrick's Flag is a flag composed of Saint Patrick's Saltire. The origin of the saltire is disputed. Its association with Saint Patrick dates from the 1780s, when the Anglo-Irish Order of Saint Patrick adopted it as an emblem. This was a British chivalric order established in 1783 by George III. It has been suggested that it derives from the arms of the powerful Geraldine or FitzGerald dynasty. Most Irish nationalists and others reject its use to represent Ireland as a "British invention" "for a people who had never used it".
