In Ireland, the Great Famine (Irish: an Gorta Mór) was a period of mass starvation, disease and emigration between 1845 and 1852. It is sometimes referred to, mostly outside Ireland, as the Irish Potato Famine because one-third of the population was then solely reliant on this cheap crop for a number of historical reasons. During the famine approximately 1 million people died and a million more emigrated from Ireland, causing the island's population to fall by between 20% and 25%. The proximate cause of famine was a potato disease commonly known as potato blight. Although the potato crop failed, the country was still producing and exporting more than enough grain crops to feed the population. Records show during the period Ireland was exporting approximately thirty to fifty shiploads per day of food produce. As a consequence of these exports and a number of other factors such as land acquisition, absentee landlords and the effect of the 1690 penal laws, the Great Famine today is viewed by a number of historical academics as a form of either direct or indirect genocide.[8] The famine was a watershed in the history of Ireland.[9] Its effects permanently changed the island's demographic, political and cultural landscape. For both the native Irish and those in the resulting diaspora, the famine entered folk memory[fn 1] and became a rallying point for various Home rule and United Ireland movements, as the whole island was then part of the United Kingdom of Great Britain and Ireland. The massive famine soured the already strained relations between many of the Irish people and the British Crown, heightening Irish republicanism, which eventually led to Irish independence in the next century. Modern historians regard it as a dividing line in the Irish historical narrative, referring to the preceding period of Irish history as "pre-Famine". Contemporary opinion was sharply critical of the Russell government's response to and management of the crisis. From the start, there were accusations that the government failed to grasp the magnitude of the disaster. Sir James Graham, who had served as Home Secretary in Sir Robert Peel's late government, wrote to Peel that, in his opinion, "the real extent and magnitude of the Irish difficulty are underestimated by the Government, and cannot be met by measures within the strict rule of economical science."[134] This criticism was not confined to outside critics. The Lord Lieutenant of Ireland, Lord Clarendon, wrote a letter to Russell on 26 April 1849, urging that the government propose additional relief measures: "I do not think there is another legislature in Europe that would disregard such suffering as now exists in the west of Ireland, or coldly persist in a policy of extermination."[135] Also in 1849 the Chief Poor Law Commissioner, Edward Twisleton, resigned in protest over the Rate-in-Aid Act, which provided additional funds for the Poor Law through a 6p in the pound levy on all rateable properties in Ireland.[136] Twisleton testified that "comparatively trifling sums were required for Britain to spare itself the deep disgrace of permitting its miserable fellow subjects to die of starvation." According to Peter Gray, in his book The Irish Famine, the government spent £7,000,000 for relief in Ireland between 1845 and 1850, "representing less than half of one percent of the British gross national product over five years. Contemporaries noted the sharp contrast with the 20 million pounds compensation given to West Indian slave-owners in the 1830s."[101] Other critics maintained that even after the government recognised the scope of the crisis, it failed to take sufficient steps to address it. John Mitchel, one of the leaders of the Young Ireland Movement, wrote the following in 1860: "I have called it an artificial famine: that is to say, it was a famine which desolated a rich and fertile island that produced every year abundance and superabundance to sustain all her people and many more. The English, indeed, call the famine a 'dispensation of Providence;' and ascribe it entirely to the blight on potatoes. But potatoes failed in like manner all over Europe; yet there was no famine save in Ireland. The British account of the matter, then, is first, a fraud; second, a blasphemy. The Almighty, indeed, sent the potato blight, but the English created the famine." en.wikipedia.org/wiki/Great_Famine_%28Ireland%29
