Presented as a gift in 1848 to Thomas Francis Meagher from a small group of French women sympathetic to Irish nationalism,[3] it was intended to symbolise the inclusion and hoped-for union between Roman Catholics (symbolised by the green colour) and Protestants (symbolised by the orange colour).



So it literally is just a cloth that was slated to become a French flag but dyed different colors and pawned off as a gift to the Irish? Neat!
aspect ratio is different , the irish 2:1 is a WIDE BOI
Ah the meaning (and motive of the French ladies who designed it) is quite distinct though no doubt heavily influenced by the flag of the French Revolution.
