events which brought the city national and international attention. One such event was the Haymarket affair. Early on the evening of the Haymarket affair in 1886, Harrison had casually observed the then still peaceful demonstration of anarchists and trade unionists and advised the police to leave the demonstrators alone; he then left the scene before the "riot" occurred. A significant reason for his ability to attend the rally unbothered was that, while Harrison came from a Protestant background, he needed the votes of and thus made appeals to the city's large ethnic White Catholic population as well as its rapidly growing numbers of trade unionists. His administration gave the impression of being more favorable to trade unions and strikes than those of previous Chicago mayors as well as other mayors of the time, although his police force routinely viciously attacked striking workers and trade union activists - as the events of later that same evening were to prove once again. Harrison was a delegate to the 1880 and 1884 Democratic National Conventions. At the 1884 convention, held in Chicago, Harrison supported the successful candidacy of Grover Cleveland, and delivered the seconding speech for Cleveland's nomination at the convention.

Oglesby. End of tenure Harrison's tenure as mayor formally ended on April 18, 1887. Initial retirement from politics Harrison retired from politics. He soon embarked on a sixteen-month world tour. In 1890, Harrison and his daughter took a vacation trip from Chicago to Yellowstone National Park and Alaska. His letters from the trip were first published in the Chicago Tribune and later compiled into an 1891 book, A Summer's Outing and The Old Man's Story.
