IRELAND
The Irish tricolour, which was adopted in 1830, is based on the French flag. The disposition of the colours (green, white and orange) was altered several times and a final decision was not taken until the 1920s. The flag was formally adopted in 1937.
Green stands for the predominantly Irish nationalist movement and orange (the colour of the House of Orange) for the Protestant community. White, in the middle, symbolises peace between the two communities.
