The Highland potato famine (Gaiseadh a’ bhuntàtastarted, in Scottish Gaelic), caused by a blight, started in 1846 and had a serious impact, because many islanders were crofters; potatoes were a staple of their diet. Violent riots became common. Charities, encouraged by George Pole and others in the Commissariat (a military agency) encouraged charities to come to the rescue. The Free Church was particularly helpful, "delivering oatmeal to famine-affected families all across the West Highlands and Islands", according to one report. Another report states that the Church "was prompt in organising an efficient system of private charity across the Hebrides and on the Western seaboard. It cooperated with the Edinburgh and Glasgow Relief Committees".
