Finally, delegates from typographers' unions in 14 cities met in Cincinnati in May 1852 and organized the National Typographical Union. A random drawing enabled the Indianapolis local to become Local Union #1 and the new headquarters. In 1869, a new Constitution was adopted, accepting the affiliation of Canadian printing trade unions and changing the name to the International Typographical Union. In 1873, at Montreal, Canada, the first ITU convention outside the United States was held. "The ITU Book of Laws" would be amended many times, yet it was as members called it "ITU Law." Each union shop was a "Chapel" and the shop steward was the "Chapel Chairman". All apprentices and journeymen had to have working cards showing paid union dues. ITU Law dictated that dues, which were proportionate to the amount of work done in the chapel, had to be paid by the first Tuesday after the last Saturday of the month. If the Union dues were not paid, the member was not allowed to work until their payment.
