He had also withdrawn privileges from the tenants, such as collecting wood from the estate. In August 1880, his labourers went on strike in a dispute over a wage increase. Lough Mask affair Historical background In the nineteenth century, agriculture was the biggest industry in Ireland. In 1876, the government of the United Kingdom of Great Britain and Ireland commissioned a survey to find who owned the land in Ireland. The survey found that almost all land was the property of just 10,000 people, or 0.2% of the population. The majority were small landlords, but the 750 richest landlords owned half of the country between them.

Landlords generally divided their estates into smaller farms that they rented to tenant farmers. Tenant farmers were generally on one-year leases, and could be evicted even if they paid their rents.

He was arrested and given a 15-year sentence for gun-running. Charles Stewart Parnell, then Member of Parliament for Meath and member of the Home Rule League, arranged to have Davitt released on probation. When Davitt returned to County Mayo, he was impressed by the Fenians' attempts to organise farmers. He thought that the "land question" was the best way to get the support of the farmers for Irish
