the town's 15,000 or so inhabitants, only 350 were Protestants. The persecution of Galway's old Catholic merchant elite meant that trade declined substantially, and the once busy harbour fell into disrepair. Local traders compensated to some degree for this by smuggling in goods like brandy through gaps in the town walls. On 1 November 1755 the 1755 Lisbon earthquake caused a two-metre tsunami to hit the city's coast, causing some serious damage to the "Spanish Arch" section of the city wall. 19th century Galway's economy recovered somewhat from the late 18th as the Penal Laws were relaxed. However the city's rural hinterland suffered terribly in the Great Irish Famine on the 1840s. Unlike other urban centres in 19th century Ireland, which experienced an explosion in their populations, Galway's population actually declined such was the devastation wrought by the famine. The second half of the century saw some improvement in Galway's position however, as the railway lines reached the city in 1850. Another important development was the creation of a university in Galway in 1845, then named "Queens University of Ireland". 20th century Galway city played a relatively minor role in the upheaval in Ireland from 1916–1923. In 1916, during the Easter Rising, Liam Mellows mobilised the local Irish Volunteers in the area to attack the Royal Irish Constabulary barracks at Oranmore, just outside Galway, however they failed to take it and later surrendered in Athenry. During the Irish War of Independence 1919–21, Galway was the western headquarters for the British Army. Their overwhelming force in the city meant that the local Irish Republican Army could do little against them. The only initiatives were taken by the University battalion of the IRA, who were reprimanded by the local IRA commander who was afraid they would provoke reprisals. This fear was not without justification, as the nearby town of Tuam was sacked on two occasions by the Black and Tans in July and September 1920. In November 1920, a Galway city Catholic priest, Fr. Michael Griffin was abducted and shot by the British forces. His body was found in a bog in Barna. Galway businessmen launched a boycott against Northern Irish goods from December 1919 onwards in protest against the loyalist attacks on Catholic nationalists in Belfast, a protest that later spread throughout the country. Before the outbreak of the Irish Civil War (1922–23), in March 1922, Galway saw a tense stand
