the Irish emigrated mainly because of a massive increase in population - to 8.5 million and the failure of the potato harvest
one study states
'The Irish state, through constant commemoration of Famine emigrants , has continually represented Irish emigrants as exiles escaping colonialism and its legacy. In addition to embracing this official version, the popular memory of migration often associated the emigrant experience with economic struggle. Due to the sheer volume of Irish people who have left the country over the past four centuries, emigration has become a fundamental part of Irish identity'
given that Sweden, Italy and other European countries also had considerable emigration across the Atlantic the Irish situation was not that differant (economic necessity exacerbated by the potato famine)
and this thread is not about the Irish and the perfidious English
