Cross of Lorraine

Similar two-barred cross symbols prominently feature in heraldry from Poland, Lithuania and Belarus.

[1] In Hungary, Béla III was the first monarch to use the two-barred cross as the symbol of royal power in the late 12th century.

During that period the Cross served as a rallying point for French ambitions to recover its lost provinces.

De Gaulle himself is memorialised by a 43-metre (141 ft) high Cross of Lorraine in his home village of Colombey-les-Deux-Églises.

The symbol was said to have helped the missionaries to convert the native peoples they encountered, because the two-armed cross resembled existing local imagery.

Also the 'dual cross' is the consonant 'gy' in ancient Hungarian runic writing which reads "egy" (one) when it stands alone mostly, if not always, with "God" meaning.

Silver double cross, on a mountain with three peaks, forms the coat of arms of the Slovak Republic.

The cross of Lorraine was previously used in the Sabre, Apollo, and Worldspan global distribution systems (GDS) as a delimiter in various input formats, however, the latest version of the graphical user interface for each system uses a different symbol: Apollo displays it as a plus sign, Worldspan as a number sign, and Sabre as a yen symbol.

The insignia was redesignated effective December 1, 2009, for the 79th US Army Reserve Sustainment Support Command in Los Alamitos, California.

The cross is used as an emblem by the American Lung Association and related organizations through the world, and as such is familiar from their Christmas seals program.
